Memory cards have become so closely embedded in the life of a modern person that he simply cannot imagine further existence without them. Memory cards have long supplanted floppy disks, disks and are even gradually replacing flash drives. The main advantage of memory cards is their miniature size, due to which the product is sufficiently mobile and convenient to use. As for the operation, not everyone still knows how to use memory cards correctly. A memory card slot, what it is, and how to use microcards correctly, we will find out in more detail.
The slot for connecting a memory card is a hole in the form of a slot up to 2.5 cm into which the device is inserted. This click is equipped with special contacts that, when a memory card is inserted, are connected to it, after which the information is read by a PC or laptop.
Standard laptops are often equipped from the factory with only one microSD card slot. How to connect a memory card to a personal computer? If your PC does not have a slot for connecting memory cards, then this problem can always be fixed. To do this, you need to purchase a portable slot or card reader, which often has at least 3 slots for different types of devices. The advantage of portable slots is their mobility and low cost.
What is a memory card
Having found out what a memory card slot is, you should pay attention to the question of what a memory card is. Memory cards are a small and thin plate made of plastic with a memory module inside. The advantage of this module is non-volatility, whereby information on the device is stored even when the product is not connected to a laptop, PC or other types of gadgets.
The information on the memory card can be deleted, recorded, rewritten in a multiple repetition mode. A memory card has a fairly long lifespan, measured in decades, provided it is handled correctly. Additionally, some memory cards are equipped with a special tab, with which you can protect the product from accidental formatting or deletion of information.
Memory cards are divided into the following types:
- SD- one of the most popular types of memory cards used on various modern gadgets. The maximum volume of such a product is 4 GB.
- SDHC- products with memory over 4 GB and up to 32 GB. They are identical in size to the previous version, only differ in cost and volume of information capacity.
- SDXC- cards that have a very large memory capacity up to 2 TB.
- MiniSD- direct analogue of the SD card, differing in the size of the product. These devices are practically not used today.
MicroSD- a very small memory card that is used in modern phones, players and other gadgets. It has a diminutive size, but at the same time, a fairly large volume up to 64 GB. The disadvantage of this size is that the product can be easily lost.
- Memory Stick- memory cards from the popular Sony company. Their maximum volume is up to 16 GB, and they can be both small and large in size.
- CompactFlash- the format of memory cards that are already outdated. The maximum capacity is 256 GB, and the advantage is high data transfer speed.
There are other types of memory cards that are also outdated and can only be found in an electronics store.
Memory Card Adapters
Laptops are equipped with slots for memory cards, which are large. But what about microSD or miniSD cards? There are special adapters for them, which are a large ordinary memory card. At the end of the adapter is equipped with a small slot through which you can install microSD memory cards.
By inserting a microSD card into the adapter, you can use the product with a device that supports large cards (laptop, card reader, camera). Adapters are often sold with small memory cards. If the adapter is not included in the kit, then it can always be purchased separately, especially since its cost is insignificant.
Features of using memory cards
The most popular memory cards in widespread use are SDHC and microSD devices. A standard memory card is rectangular with a cut off corner. This corner is cut so that the card can only be inserted into the slot with one side.
It's important to know! If, when you try to insert a card into the slot, nothing comes of it, then you should turn the product 180 degrees and try to install it into the slot again. If the card is inserted correctly, a click will follow.
To remove the card, you need to press on it with your finger or fingernail, after which a characteristic click will follow, and the product will jump out of the slot. The principle of installing cards, both in laptops and in photo and video equipment, is identical. To insert the card into the card reader, it is enough to position it in the correct position and stick it into the slot. When the card is inserted into the card reader, it does not enter the slot completely, but only in large part, which simplifies the way to remove it.
If it becomes necessary to transfer information from the phone, which is stored on the memory card, to a laptop, then an adapter is needed for this. The microSD card can be inserted into the slot of the laptop using an adapter or adapter. To begin with, the microcard is installed in the adapter, and only then the latter is inserted into the slot.
How to read information from a memory card on a PC
If there are no slots for connecting memory cards on the PC system unit, then a card reader can be purchased for this. The product represents a small plastic box with several slots for connecting cards. On the other hand, the device has a USB connector through which the product is connected to a computer.
Determining the visibility of a memory card by the computer is quite simple, for which you should double-click on the "My Computer" icon. An icon of a memory card or an additional disk will appear in the window that opens, which is the connected product.
To open the contents of the map on a computer, just double-click on the folder. In the window that opens, you can copy the necessary files to transfer to the PC memory or vice versa. At the end, be sure to properly learn how to remove the memory card. To do this, you need to find in the lower right corner the flash drive icon with a green arrow. You need to click on this icon once, and then select the "Safely remove hardware ..." function from the pop-up window.
It's important to know! If the memory card is removed in a safe manner, the shelf life of the product will be significantly reduced. In addition, the shelf life of the card reader and the slot itself on the laptop is reduced.
In conclusion, it should be noted that although memory cards are easy to use, it is imperative to follow the rules and recommendations for their use. It is not recommended to store memory cards near electromagnetic radiation, as they affect the shelf life of the products.
For most people, microSD is just a form factor, but it really isn't. You can easily insert any microSD card into a standard slot, but not all of them will work, since cards differ in many ways.
Format
There are three different SD formats in total, available in two form factors (SD and microSD):
- SD (microSD) - drives up to 2 GB, work with any equipment;
- SDHC (microSDHC) - drives from 2 to 32 GB, work on devices with support for SDHC and SDXC;
- SDXC (microSDXC) - drives from 32 GB to 2 TB (currently 512 GB maximum), only work on devices with SDXC support.
As you can see, they are not backward compatible. New format memory cards will not work on older hardware.
Volume
The manufacturer's declared support for microSDXC does not mean support for cards of this format with any size and depends on the specific device. For example, HTC One M9 works with microSDXC, but officially only supports cards up to and including 128GB.
One more important point is connected with the volume of storage devices. All microSDXC cards use the exFAT file system by default. Windows has been supporting it for over 10 years, in OS X it has appeared since version 10.6.5 (Snow Leopard), in Linux distributions exFAT support is implemented, but it does not work out of the box everywhere.
High speed UHS interface
I or II is added to the logo of a UHS-enabled card depending on the version SDHC and SDXC cards can support Ultra High Speed, which, when supported by hardware on the device, provides higher speeds (UHS-I up to 104 MB / s and UHS-II up to 312 MB / s). UHS is backward compatible with earlier interfaces and can work with devices that do not support it, but at standard speeds (up to 25 MB / s).
2. Speed
Luca Lorenzelli / shutterstock.com Classifying the write and read speed of microSD cards is as complex as their formats and compatibility. The specs allow four ways to describe card speed, and since manufacturers use all of them, there is a lot of confusion.
Speed class
Speed class marking for ordinary cards is a number inscribed in the Latin letter C The speed class is associated with the minimum write speed to the memory card in megabytes per second. There are four of them:
- Class 2- from 2 MB / s;
- Class 4- from 4 MB / s;
- Class 6- from 6 MB / s;
- Class 10- from 10 MB / s.
By analogy with the labeling of ordinary cards, the speed class of UHS cards fits into the Latin letter U The cards operating on the high-speed UHS bus have only two speed classes so far:
- Class 1 (U1)- from 10 MB / s;
- Class 3 (U3)- from 30 MB / s.
Since the speed class designation uses the minimum record value, theoretically a second-class card may well be faster than a fourth-class card. Although, if this is the case, the manufacturer will most likely prefer to state this fact more explicitly.
Maximum speed
The speed class is quite enough for comparing cards when choosing, but some manufacturers, in addition to it, use the maximum speed in MB / s in the description, and more often not even the write speed (which is always lower), but the read speed.
These are usually synthetic test results under ideal conditions that are not achievable with normal use. In practice, the speed depends on many factors, so you should not focus on this characteristic.
Speed multiplier
Another classification option is a speed multiplier, similar to the one used to indicate the read and write speed of optical discs. There are more than ten of them, from 6x to 633x.
The 1x multiplier is 150 KB / s, that is, the speed of the simplest 6x cards is 900 KB / s. The fastest cards can have a multiplier of 633x, which is 95 MB / s.
3. Tasks
StepanPopov / shutterstock.com Choose the right card based on specific tasks. The biggest and fastest is not always the best. For certain usage scenarios, volume and speed may be overkill.
When buying a card for a smartphone, volume plays a greater role than speed. The advantages of a large storage device are obvious, but the advantages of a high transfer speed on a smartphone are almost not felt, since large files are rarely written and read there (unless you have a smartphone with 4K video support).
Cameras that shoot HD and 4K video are a whole different matter: speed and volume are equally important here. For 4K video, camera manufacturers recommend using UHS U3 cards, for HD - regular Class 10 or at least Class 6.
For photography, many professionals prefer to use several smaller cards in order to minimize the risk of losing all images in case of force majeure. As for the speed, it all depends on the photo format. If you shoot in RAW, it makes sense to invest in a microSDHC or microSDXC class UHS U1 and U3 - in this case, they will fully reveal themselves.
4. Counterfeits
jcjgphotography / shutterstock.com No matter how trite it may sound, buying a fake under the guise of original cards is now easier than ever. Several years ago, SanDisk claimed that a third of SanDisk memory cards on the market were counterfeit. It is unlikely that the situation has changed much since that time.
Common sense is enough to avoid disappointment when buying. Refrain from buying from untrustworthy sellers, and beware of offers of "original" cards that are significantly below the official price.
Attackers have learned to counterfeit packaging so well that sometimes it can be very difficult to distinguish it from the original. It is possible to judge with complete confidence about the authenticity of a particular card only after verification using special utilities:
- H2testw- for Windows;
If you have already faced the loss of important data due to a broken memory card for one reason or another, then when it comes to choosing, you will most likely prefer a more expensive card of a well-known brand than an affordable "no-name".
In addition to the greater reliability and safety of your data, with a branded card you will receive a high speed of work and a guarantee (in some cases even a lifetime).
Now you know everything you need to know about SD cards. As you can see, there are many questions that you will have to answer before purchasing the card. Perhaps the best idea is to have different cards for different needs. This way you can take full advantage of the equipment and not expose your budget to unnecessary expenses.
Of course, many people know about memory cards. Someone may even be surprised - why do we need an article about them at all. However, not all so simple. Among my acquaintances there are many people who do not really know anything about memory cards. Nor do they live in a hut in the forest, feeding on spruce cones. They quite actively use the Internet, mobile phones, sometimes even communicators and tablets. Therefore, I consider it necessary to first tell you about what memory cards are. And then I will move on to considering their varieties, classes, brands.
What is it - a memory card?
A memory card is such a small and rather plump plate with a built-in flash memory module. This module is non-volatile, that is, information on the memory card is saved even while it is removed from any device. Information on the memory card can be deleted, overwritten, and so on. The service life of the memory card is very long - tens of years. Information on some cards can be protected in certain ways.
Types of memory cards
There are a whole bunch of different types of memory cards. I will only talk about the most common ones.
SD (Secure Digital). Perhaps the most popular type. It is used in many cameras, camcorders, tablets, old players, communicators and pocket computers. Differs in a low price. It is sold in almost all communication stores, computer stores, in many markets, in kiosks ... The maximum volume is 4GB.
SDHC. All SD memory cards larger than 4GB (and many 4GB) are called SDHC (maximum 32GB). This format has a higher speed of operation (data exchange, data recording) than SD. It is preferable, of course, to purchase SDHC cards, but keep in mind that some older devices may not work with them.
SDXC... A new standard not yet widely adopted. SDXC cards are very large in capacity - up to 2 terabytes (which is 2048GB!) And very high data writing speed. They are still expensive and are not very common on sale. Moreover, very few devices still support this format.
MiniSD. Similar to SD, but noticeably smaller. Nowadays, it is practically not used anymore, the microSD format has replaced miniSD. It is problematic to buy miniSDs now, but they are expensive due to their rarity.
MicroSD (TransFlash). It is probably currently the second most popular format after SD / SDHC, but in the near future it has every chance of becoming the most popular memory card format. Differs from SD in very small size; microSD cards are even smaller than miniSD cards. This is both a plus and a minus: on the one hand, with the advent of microSD, it became possible to reduce the size of devices; on the other hand, such a miniature card is easy to lose. Prices for microSD cards are almost identical to those for SD cards.
MicroSDHC... MicroSD cards larger than 4GB (and many 4GB) are called microSDHC (max 32GB). This format has a higher speed of operation (data exchange) than microSD. It is preferable, of course, to purchase microSDHC cards, but keep in mind that some older devices may not work with them.
Memory Stick. Memory card format developed by Sony; is closed. The speed of work (writing / reading data) is high; the maximum volume is 16GB. There are both large Memory Sticks and small Memory Stick micro (M1, M2). The Memory Stick is distinguished by its high price (in my opinion, clearly overpriced). Used in Sony, Sony Ericsson devices. It is often found on sale, almost everywhere.
CompactFlash. An obsolete format previously widely used in the PDA. CompactFlash cards are very large compared to SD cards. Currently used by only a few users. The main advantages are very high data writing speed. The maximum volume is 256GB.
SmartMedia... This is an obsolete format. It is almost impossible to buy SmartMedia cards, and their maximum capacity is only 128 MB.
MMC... Also an outdated format, formerly a competitor to SD. It differs from SD in slightly smaller thickness and greater efficiency. MMC cards can be inserted into the SD slots of the devices (but the SD card cannot be inserted into the MMC slot!). Nowadays, MMC cards are rarely found on sale.
xD... Format developed by Olympus and Fujifilm; is now slowly falling out of use. XD cards are very expensive; only Olympus and Fujifilm devices work with them. In comparison with SD cards xD, perhaps only worse - for example, the maximum capacity of xD is only 2GB.
Memory card slots
If a device allows the use of memory cards, it is said to have a memory card slot. A slot is a hole (slot) where a memory card is inserted. (Of course, this is not a simple click, but a special click: special contacts are connected to it, with the help of which information is read from the cards). One device may have slots for different types of memory cards, but usually there is only one slot. And in most modern devices - for microSD.
Memory Card Adapters
As you learned from the above material, memory cards can be divided into two types (according to size): large and small. Most popular large cards: SD and Memory Stick. The most popular small ones are microSD and Memory Stick Micro. It can be replaced that the technology of SD and microSD, in general, is the same, the difference is only in size and some details. That is why it is possible to use so-called adapters (some call them "shirts").
An adapter is a device, like two drops of water, similar to a large memory card, but in reality it is a kind of miniature box. You can insert a small memory card (for example, microSD) into it, and after that the adapter itself will turn into a full-size memory card (for example, SD). The small card in the adapter can be used with a device that only supports large cards. A classic example is to put a microSD card from your phone into a camera that supports SD cards.
All this provides versatility, the ability to quickly and conveniently transfer data from one device to another without using a computer. That is why it is better to buy a microSD card - you can always use it with a device that supports SD cards. But the opposite is impossible: the size of an SD card cannot be reduced in any way!
It's worth noting that adapters are usually sold with small cards. But even if there is no adapter in the kit, you can buy it additionally - the price of the issue is usually no more than 100 rubles. It is not necessary to buy an adapter from the same company that produced the small memory card: there is no difference between adapters of the same format from different manufacturers.
SDHC / microSDHC memory card classes
On packages (and often on the cards themselves) with SDHC / microSDHC cards, you can read information about the so-called class of the card. It is designated by a digit (number). The higher the number, the faster the card (read and write speed). Usually, the higher is the power consumption of the card and, of course, its price. Here is a list of these classes:
- class 2 - data writing speed not less than 2Mb / s
- class 4 - data writing speed not less than 4Mb / s
- class 6 - data writing speed not less than 6Mb / s
- class 10 - data writing speed not less than 10Mb / s
- class 16 - data writing speed not less than 16Mb / s
There are also "no class" SDHC cards on sale - the data writing speed on them usually does not exceed 1Mb / s. Also, cards with an even higher write speed (of a higher class) appeared on the market, but I see no reason to buy them - the price is high, and the benefits are doubtful.
For cameras and camcorders, it is advisable to buy memory cards of a class not lower than class 4 (although, in principle, class 2 and even "classless" cards are sufficient for amateur photography). For high-definition video recording, a class 6-10 card or higher is desirable. For readers and phones, the most ordinary cards "without a class" will be enough.
Memory card capacity
Many people have a question - what capacity memory card should you buy? The answer, in general, is simple - you have to proceed from your own needs. Hopefully the following list will help you identify them, which shows how much memory is used by different types of files:
- DOC, XLS documents - usually within 1Mb
- Electronic book (FB2, EPUB, TXT, MOBI) - usually within 1MB
- 8-10Mpix photo of excellent quality - usually within 3Mb
- Photo 5MPix of good quality - within 1MB
- Song 3 minutes in average quality - about 3Mb
- Song 3 minutes in good quality - about 6Mb
- Movie in more or less decent quality - about 500MB or more
- Movie in good quality - usually 1GB or more
I also give one more list, which indicates what volume of cards it makes sense to buy based on what device you buy them for:
- For a reader (reader) - 4GB is enough
- For a phone - 4GB is enough
- For a communicator (smartphone) - better than 8GB, or even 16GB
- For a tablet - 16GB is better, if you like to watch movies - 32GB
- For a camera - 4GB (if you shoot only photos and not very much), 8-16GB (if you shoot a lot of photos and occasionally - video)
- For a camcorder or a camera that shoots video in good quality - 16GB, or better 32GB
Card Readers
Memory cards are mainly intended for use in portable devices - digital cameras, players, phones, tablets. But if desired, they can be connected to both laptops and desktop computers. This requires a small device called a cardreader. Some (usually quite expensive) laptops and desktops have a built-in card reader; for others, you need to buy a separate device, its cost ranges from 150 to 700 rubles (in very rare cases, higher).
The card readers are connected to the USB port of the computer / laptop. First you need to insert the card into the card reader, then connect it to the computer. A removable disk will appear in Explorer - this is the memory card; you can work with this removable disk as with a regular flash drive. At the end of the work, the card reader must be removed from the USB port (after “safely disconnecting” the device), and then the memory card must be removed from the card reader. Such a simple mechanic.
Perhaps the more popular are card readers designed to work with only one type of memory card - for example, SD. They are distinguished by their low price and compact size. Card readers for microSD cards, by the way, are very small, and they can be used like ordinary flash drives - just insert a microSD card into the card reader. Of course, you can use SD, xD and so on card readers as a flash drive, but their size is noticeably larger.
So-called universal card readers are now widespread. With them, you can use memory cards of almost all formats: SD, microSD, Memory Stick, Memory Stick micro, and so on. They are, of course, larger than the usual "mono" card readers, and are somewhat more expensive. But personally, I recommend purchasing just a universal card reader - after all, you can use any cards with it.
Some features of memory cards
Perhaps, memory cards have only one drawback: they are rather gluttonous. This means that a device without a memory card inserted will work longer without recharging than its counterpart with a memory card in use. However, the difference in operating time is usually small, and I would not call this disadvantage significant.
Another feature of memory cards is open (in the overwhelming majority of cases) contacts. Accordingly, you need to be quite careful, try not to damage these contacts (do not scratch, for example), do not allow dust and dirt to accumulate on them.
Another feature of memory cards is that some models of the same type may not be compatible with specific electronic devices. In practice, this means that the SD card may simply refuse to work with your reader, phone or tablet: the case here, as a rule, lies in some minor flaws in the device software. This feature must be borne in mind, and when buying a memory card for a device, you must check its compatibility with this device. Failure to do so may lead to disappointment.
Memory card manufacturers and brands
Many electronics manufacturers produce memory cards. Perhaps the most famous are SanDisk and Transcend. They issue cards in various formats and classes; the prices for SanDisk and Transcend products are quite high. At the same time, SanDisk cards (and Transcend), for example, do not work with some devices - it is not known who should be blamed here, but the fact remains, and you should not think that the high price automatically guarantees absolute compatibility. But in general, the cards from SanDisk and Transcend are very high quality.
Kingston and Apacer memory cards have a lower price. Their compatibility is also not absolute, but I can say that Kingston cards (according to my subjective feelings) are compatible with a larger number of devices than SanDisk. In general, Kingston is a kind of golden mean, excellent value for money. Apacer cards are usually slightly worse in quality, and their compatibility level is lower, but their price is even more modest.
Of course, memory cards are also produced by other manufacturers: Toshiba, Samsung, Silicon Power, A-Data, and so on. The list is very long, I see no reason to cite it in its entirety. In any case, all of the above manufacturers produce sufficiently high-quality products that you can buy without fear (but - preferably - with testing on a specific device).
To be honest, most of all I do not like testing, the result of which is completely obvious to me. But sometimes, as practice shows, you have to do it. In any case, the question of how various adapters affect the speed of SD cards is raised over and over again in our Conference, although it would seem that the answer is elementary. And after the release of the last part of testing memory cards on a mobile platform, a lot of letters came to me. Let me remind you that in this article I had to use an adapter from microSD to miniSD for testing, and the device for which I had to do this showed the lowest results. So readers later asked - could this be due to the use of an adapter? To answer every time, frankly, too lazy. And words - they are words. Therefore, I decided to spend a certain amount of time writing this article, in order to refer to it if necessary :)
Let's start with a small digression into history - so that it is clear what the actual problem is. The first and for a long time the only format for SD-cards was the "full-size" models themselves. We have already spoken about the features of the format more than once, but now it is important that they were produced (and are still being produced) in a case with dimensions of 32 × 24 × 2.1 mm, and for communication with the outside world they use a contact group of 9 contacts. For a long time, these cards were one of the most compact on the market, but the process of miniaturization of devices required the development of more compact media. These are miniSD cards with dimensions of 21.5 × 20 × 1.4 mm and 11 contacts. Coupled with the different card widths, this makes it impossible to easily install miniSD into an SD slot. In order to do this, there are passive adapters, when used, the card becomes outwardly indistinguishable from SD. The compatibility at the logical level is complete - the two new contacts have never been used in any way, the synchronization frequency and other operating logic are the same. However, progress in terms of miniaturization of mobile devices did not want to stop, so after a while microSD cards appeared on the market, measuring 15 × 11 × 1 mm with an 8-pin connector. Again, being physically incompatible with their ancestors, they nevertheless retained full logical compatibility. Well, since at the time of the release of these cards the market for accessories suitable for them was still undeveloped, it became a good practice to equip the card with an adapter similar in function to that supplied with miniSD.
For a long time the situation was the same as described above - SD as a common denominator, lack of compatibility between the two miniature formats and one adapter complete with their representatives. Later, the situation became more interesting. For example, manufacturers today sometimes sell microSD cards without adapters in the kit: there are card readers focused on them, and the user may already have an adapter obtained with a previously purchased card. Roughly the same explains the existence on the market of sets of two cards with one adapter - a pair is sometimes more convenient, but why two adapters? Well, some microSD cards today are equipped with two adapters at once - for the "full-size" and for the mini-version. Like all universal options, this one often looks very attractive. Moreover, the offer for miniSDHC cards leaves much to be desired - this format (along with its non-NS-modification) is leaving the market.
It would seem that everything is simple. However, significantly different cases and, in particular, the different number of contacts in the connector constantly lead to vague suspicions that not everything is so simple there. What if the adapter is not a simple passive, but contains some kind of logic of work? In this case, it will obviously have an effect on the speed of the cards. Well, let's check whether it works or not, more precisely, we will demonstrate that it does not.
So, the recently tested Kingston FCR-HS219 / 1 card reader provides direct support for both "full-size" Secure Digital cards, as well as miniSD, and microSD, which we will use now: if the same card using different adapters will work in all variants the same, therefore, the influence of the adapter is absent.
Its kit contains an adapter for the "full-size" version, but for the purity of the experiment, I used an adapter from a GOODRAM microSD 1 GB memory card. Note - not even microSDHC, but microSD, that is, if the influence of the adapter existed, our card with this adapter would hardly work at all;)
 |  |
And to ensure the compatibility of the card with the miniSD slot, I (like when testing communicators, by the way) used an adapter from the Patriot microSD card kit.
Otherwise, everything is as usual. Testing was carried out on a computer with the following configuration:
- EpoX 8NPA SLI
- AMD Athlon 64 3200+ (512K L2)
- 1 GB PC3200 DDR SDRAM
- system hard drive Western Digital WD1600JS
- Windows XP Pro + SP3
To measure the parameters of the subjects, the program Lavalys Everest Ultimate Edition 2006 2.80 was used, or rather, the disk drive test included in it.
I will give all the diagrams in bulk, since they do not need comments.
As I warned at the very beginning, I did not try to find anything new with the help of this testing. And he could not :) In fact, the article can be considered part of the FAQ on SD-memory cards - the answer to the question whether adapters affect the high-speed or any other characteristics of cards. Moreover, a detailed answer - with practical evidence.
Some phones have slots for memory cards (usually microSD format).
If your phone supports SD cards, you can:
- increase storage capacity by inserting such a card;
- use the map for some functions and applications.
Note. Some of these steps can only be performed on devices running Android 6.0 and later.
