How To Tell If You Are Buying the Right SD Card

Secure digital (SD) cards are used in all sorts of devices, from computers to camcorders to prison cell phones, which means y'all'll probably discover yourself needing to buy some. But how do you know if you're buying the right 1? There are tons of options out there, and they're hard to tell apart, just the notable difference in price indicates thatsomething makes them distinct. How can you tell if you're getting the right 1 for your device? Here are four things that you need to bank check before you brand a purchase.

Size

There are three different sizes of SD cards: standard, micro, and mini. The standard SD card is one you're probably familiar with. Its 32 ten 24mm size is small-scale, only it'due south actually the largest SD carte du jour size available. Near computers, cameras, and camcorders utilize this size. Many microcontrollers and single-board computers (like the Raspberry Pi, and the Arduino with an adapter) use this size, likewise.

The mid-size option, at 21.v x 20mm, is the miniSD. This size is much less mutual, though it is used in some cellphones. Many miniSD cards include an adapter that allows them to exist used in standard-sized SD card slots, like this one from SANOXY:

Much more common than miniSD, however, is microSD. These cards are tiny, at 11 x 15mm, which makes them great for cellphones and tablets. As with the miniSD cards, it'southward like shooting fish in a barrel to find adapters that volition permit you use microSD cards in standard-sized slots, similar the adapter that comes with this Transcend 64GB microSD card:

The size of carte du jour that y'all use depends entirely on your device. If it has a standard SD card slot, y'all'll need to use a standard SD card or a smaller i with an adapter. If it has a miniSD slot, you lot'll need a mini or micro with adapter. And if it has a microSD slot, you'll only exist able to utilise microSD cards with it.

Menu Type

At that place are 3 different SD menu formats: SD, SDHC, and SDXC. For the most office, their labels are correlated with capacity. SD cards tin can store up to 2GB, SDHC up to 32GB, and SDXC cards tin can shop more than than 32GB. Most every device and bill of fare reader can read SD and SDHC cards, but if you want to use a carte that can store more than than 32GB of data, you'll demand to consult the owner's transmission of your device to make sure that it's compatible with SDXC-format cards (this is condign increasingly common).

Each card's label indicates the format of the card with one of the following logos:

Chapters

If you've looked at the legions of SD cards available, yous'll probably have noticed that in that location'due south a huge range of capacities bachelor. Early SD cards were available with capacities of 32 and 64MB, merely the smallest SD bill of fare that most people will consider today holds 2GB. And while at that place might be larger ones out at that place, very few people will be interested in an SD menu with a capacity of more than 512GB (these monsters are bachelor from PNY).

Of course, you lot almost certainly don't need to spend $350 to get 512GB worth of storage. Instead, you'll demand to think almost what you're going to be using your SD card for. For example, if you lot want to use a microSD carte du jour to concur more music on your phone, 16GB volition exist enough. Depending on the quality of the music, you'll probable be able to add somewhere between ii,000 and 3,000 songs to that menu.

Even an 8GB card will concord over 2,000 compressed photos, making it a safe choice for phones, tablets, and cameras that you plan on taking pictures with. If yous're using a DSLR, the file size will be larger, and so y'all'll have room for fewer pictures. This is especially true if you relieve your images in RAW format, which can be upwardly to 25MB per or more than per image. If you lot take a lot of RAW photos, y'all may need an even larger card, like a xvi or 32GB.

Storing video on an SD carte du jour requires even more infinite. According to SanDisk, most iv hours of standard HD video can be stored on a 16GB bill of fare. Less than 3 hours of high-quality Hd video would fit on the same card.

These estimates come from making some assumptions, but they can be used as a guide to aid you figure out if you're ownership the right capacity SD card. Fortunately, nearly SD carte manufacturers will give yous an idea of how much data you lot tin can fit on a bill of fare, whether on the SD menu packaging or on the manufacturer's website.

Speed Class

I of the to the lowest degree-well-understood parts of SD card nomenclature is speed class, which states how fast data tin can be written to the bill of fare. Fortunately, this table from the SD Association makes it very clear:

If you're non using your SD bill of fare to tape video, yous don't need to worry about the speed grade; writing data from a computer or a camera doesn't demand to exist at super high speeds (though it certainly doesn't hurt to have a faster card). If you're using your card to record video, though, y'all should check this tabular array to make sure that the carte you're using is fast enough for the blazon of recording you want to do.

For case, if you're going to be filming in HD, you should have a Class 6 or faster card, and Class 10 would exist better, especially if you're going to be taking HD stills besides during the video. If you're going to exist recording in 4K, a UHS 3 carte du jour will be required. The speed class of every menu is displayed direct on the card. Simply reference the graphic on the card and look at the table above.

Wifi

One of the most useful features you might be surprised to find out that SD cards can include is wifi connectivity. While this idea was popularized by the Eye-Fi SD card, but a number of other brands, including Toshiba and Transcend, now offer continued options as well. When using a wifi-connected SD card in your camera, yous can wirelessly transfer your photos to either your computer or a smartphone.

While this isn't an essential characteristic, it can be very nice, especially if you have a tendency to accidentally forget your SD menu in your calculator or card reader. Plain, you lot'll pay more than you would for a non-wifi-enabled card. A 32GB card from Center-Fi costs $76, or $100 for one that comes with some professional person-level features, like automatic photo nomenclature.

Choosing the Right Card for You

If you empathise these iv qualities of SD cards, you should have no trouble finding the right card for your needs, whether information technology's for storing extra documents from your computer or recording 4K video. Past looking at the size required by your device, determining how much chapters you demand, understanding the difference between speed classes, and thinking about wifi connectivity, y'all'll limit your seemingly endless choices for an SD card downward to a much more reasonable option.
