The very best microSD playing cards in 2024

Most microSD playing cards are quick sufficient for reinforcing cupboard space and making easy file transfers, however some present a bit of extra worth than others. For those who’ve acquired a tool that also accepts microSD playing cards — whether or not it’s a gaming handheld, a touch cam, a drone or an Android tablet — we’ve scoured the market and put greater than a dozen high contenders via numerous benchmark checks. You could find our high suggestions beneath, alongside some basic procuring recommendation earlier than you seize one.

What to search for in a microSD card

Capability

The very first thing to determine when shopping for a microSD card is how a lot cupboard space you want. Fashionable playing cards are often accessible in sizes starting from 32GB to 512GB, whereas an growing quantity can be found in 1TB as nicely. 2TB playing cards from respected producers are getting closer however aren’t extensively accessible simply but.

For many, a 128GB or 256GB mannequin needs to be the candy spot between value and cupboard space. However if you happen to want extra room — say, for stashing a bunch of video games on a Steam Deck — a 512GB or higher card might make extra sense and infrequently offers a greater cost-per-GB ratio. As of late, yow will discover an honest 128GB card for round $15 or much less, a superb 256GB card for lower than $30 and a stable 512GB card for lower than $40 (although many value nearer to $50 or $60). There’s a starker enhance if you go as much as 1TB playing cards, which generally value nearer to $100.

Observe {that a} microSD card’s efficiency might differ relying on what capability you purchase. SanDisk says its 128GB Extreme card delivers sequential write speeds as much as 90 MB/s, for instance, whereas the higher-capacity fashions in the identical line provide as much as 130 MB/s.

Once we discuss microSD playing cards immediately, we often discuss with playing cards that use the microSDXC (eXtended Capacity) standard, which have a capability between 32GB and 2TB. Your gadget must help this for it to work with a microSDXC card. This may nearly by no means be a difficulty lately, however some older units (a Nintendo 3DS, for example) are solely appropriate with microSDHC (Excessive Capability) playing cards, which vary from 2GB to 32GB.

Learn and write speeds

MicroSD playing cards are primarily judged on their learn and write speeds, that are often measured in megabytes per second (MB/s). Typically, most microSD playing cards have sooner learn speeds than write speeds.

These metrics can then be damaged down into sequential and random efficiency. Sequential learn and write speeds matter if you’re attempting to entry or save lengthy, fixed streams of information, reminiscent of opening a big video or copying an enormous batch of information from a PC. If you wish to use a microSD card for media storage, that is significantly essential. Random efficiency, in the meantime, is about how rapidly a card can learn and write small information scattered all through the gadget.

Since random learn/write speeds are a lot decrease than sequential ones, storage gadget makers have a tendency to not promote them as loudly. However they’re essential if you happen to use a card with a gaming gadget or a single-board laptop just like the Raspberry Pi, the place it typically has to quickly save and entry small bits of information in random places.

Velocity rankings

For those who have a look at a microSD card, you’ll see a buffet of numbers, letters and symbols. Most of those discuss with the cardboard’s speed class and efficiency rankings, that are decided by the SD Association.

A card’s Video Velocity Class, or V-rating, particulars its minimal sequential write velocity, which is very essential when recording video from a digicam. It ranges from V6 to V90. A lot of the playing cards we examined had a V30 score, in order that they have a sequential write velocity of no less than 30 MB/s. This needs to be sufficient to help as much as 4K video at decrease bitrates. Greater-rated V60 and V90 playing cards are often higher for capturing 8K, however they arrive at a a lot larger value.

The UHS Velocity Class, or U-rating, additionally refers to a card’s minimal sequential write velocity. It is available in two varieties: U3, which mandates a minimal of 30 MB/s, and U1, which is rated for 10 MB/s.

The older Velocity Class score overlaps with the opposite two methods. It’s signified by a C image and goes from Class 2 to Class 10, with the quantity (once more) indicating minimal sequential write velocity. This score is much less related these days, however you should still see a “C10” brand on some playing cards.

The Software Efficiency spec, marked by an A logo, is an indicator of random learn/write speeds. That is measured in IOPS, or enter/output operations per second, somewhat than MB/s. There are two classes right here: A1 playing cards provide a minimal random learn velocity of 1,500 IOPS and a minimal random write velocity of 500 IOPS, whereas A2 playing cards bump these as much as 4,000 IOPS and a couple of,000 IOPS, respectively. Each rankings additionally assure sequential write speeds of no less than 10 MB/s.

To maintain it easy, most individuals ought to search for a card with V30, U3 and A2 rankings. It’s completely potential to get a stable card with out these: A U1 card could be value it if you happen to simply want an inexpensive, high-capacity choice, for instance. V60 and V90 playing cards are value a glance if you happen to’re severe about capturing high-resolution photographs and video as nicely. However general, playing cards with the certifications above ought to present the most effective mix of value and efficiency immediately.

It’s essential to emphasise that these rankings are baselines. Most V30 playing cards provide considerably larger write speeds than 30 MB/s, for example, and a few A1 playing cards can outperform some A2 fashions in observe. The speeds marketed by producers aren’t at all times 100% correct, both: Typically the cardboard will likely be slower in real-world use, different occasions it could truly be a bit sooner.

UHS bus speeds

The opposite spec to notice is the cardboard’s bus interface. Most microSD playing cards accessible immediately are UHS-I, which have a theoretical most velocity of 104 MB/s. There are additionally UHS-II playing cards, which have an additional row of pins on the again and might attain as much as 312 MB/s. (A UHS-III customary exists as nicely however hasn’t seen large adoption.) These are labeled on the cardboard with a Roman numeral I or II.

The quickest microSD playing cards you should buy proper now are UHS-II playing cards, they usually’re often those with V60 or V90 rankings. For those who shoot a number of 4K to 8K video or continuously use burst mode to seize extremely high-res photographs, the efficiency positive aspects of a superb UHS-II card can prevent time.

However these are rather more costly than UHS-I playing cards: This 128GB Lexar Professional Gold mannequin, for example, is a relative cut price at $40. Whereas that is lower than many UHS-II fashions we’ve seen up to now, it is nonetheless greater than double the standard value of our high decide talked about beneath. You want a tool that’s appropriate with the UHS-II interface to see any advantages, too, and inventory for UHS-II playing cards is usually spottier. For now, the upper speeds aren’t well worth the value premium for most individuals, so we caught largely to UHS-I playing cards right here.

We’ll additionally be aware Samsung’s announcement earlier this yr of a brand new 256GB microSD card primarily based on a completely completely different customary referred to as SD Categorical. That is theoretically a lot sooner than any UHS-I or UHS-II choice: Samsung claims this particular mannequin can attain sequential learn speeds as much as a whopping 800 MB/s. For context, that’d be faster than some older SSDs. SD Categorical has technically been around for a number of years however hasn’t seen large adoption, so precisely how this card performs in actuality — and the way a lot it’ll value — stays to be seen. We’ll take a look at the gadget as soon as it turns into accessible, which Samsung says will likely be someday later in 2024.

A be aware on card readers, the Nintendo Swap and Steam Deck

Whereas the UHS-I spec has a theoretical most of 104 MB/s, some UHS-I playing cards can exceed that velocity via proprietary extensions. You want a appropriate card reader and host gadget to make the most of that further efficiency, although. For those who discover a UHS-I card promoting speeds larger than 104 MB/s, that is what’s happening. You may see these limits in motion with a Nintendo Swap or Steam Deck: Both of those gaming units help the UHS-I interface and don’t transcend its official velocity, flattening any sequential positive aspects some playing cards might have elsewhere. The broader takeaway: Your microSD card will solely be as quick because the slowest hyperlink in your chain.

Guarantee

Many microSD playing cards are designed to be sturdy, with safety from water, excessive temperatures, X-rays and drops. Nonetheless, in case of disaster, a protracted guarantee is at all times good to have. Many producers provide lifetime or 10-year restricted warranties, although we’ve observed that “endurance” playing cards marketed to resist extra hours of writing are often coated for a shorter time period. For instance, Samsung’s Pro Endurance, a mannequin geared toward safety cameras and different monitoring units, comes with a five-year guarantee.

Avoiding counterfeits

The reminiscence card market has had a selected drawback with scammers promoting pretend merchandise. To protect in opposition to this, solely purchase from a identified model and a good retailer reminiscent of Greatest Purchase, B&H Photograph or Adorama. For those who store at Amazon, solely purchase if the shipper and vendor is Amazon.com. (Although a handful of customers have reported receiving counterfeits even from Amazon straight up to now.) Keep in mind: If a value appears too good to be true, it most likely is. Be cautious of any retailer providing considerably a cheaper price than others.

When you obtain a card, examine its packaging for any irregularities. You may run benchmark checks like CrystalDiskMark or BlackMagic Disk Speed Test to confirm its speeds aren’t drastically decrease than what’s marketed (or potential, given its specs). You can too use software program that’s designed to confirm the true capability and efficiency of your card, reminiscent of H2testw and FakeFlashTest.

How we examined

We put 13 microSD playing cards via a sequence of checks to confirm their sequential and random efficiency. These included benchmarks like CrystalDiskMark, BlackMagic Disk Speed Test, ATTO Disk Benchmark and AJA System Test, in addition to just a few “real-world” checks. We copied and pasted a small folder of photographs about 1.15GB in measurement to and from every card, then did the identical with a bigger 12.2GB folder containing a number of file varieties and subfolders, timing the method every time. We additionally checked how every card carried out on the Steam Deck, downloading video games of various sizes — together with Stardew Valley, Aperture Desk Job, Metal Gear Rising: Revengeance and Apex Legends — then timing how lengthy it took to launch every recreation and cargo save information.

We used a Kingston USB 3.2 UHS-II reader to check every card on each Home windows 11 and macOS Sonoma. For the previous, we used an Alienware gaming PC with an Intel Core i9-10900F, Nvidia GeForce RTX 3080 GPU, 32GB of RAM and a 1TB SSD. For the latter, we used a 2021 16-inch MacBook Professional with an Apple M1 Professional chip, 16GB of RAM and a 512GB SSD. To make use of our card reader on the MacBook, we used Apple’s USB-C Digital AV Multiport Adapter.

We examined the 128GB model of every card wherever potential, although for just a few playing cards — SanDisk’s Excessive and Samsung’s Professional Plus and Professional Final — we have been solely in a position to take a look at their 256GB fashions. We additionally reformatted every card earlier than testing with the SD Affiliation’s Memory Card Formatter tool.

Greatest microSD playing cards of 2024

Storage capability: 128GB, 256GB, 512GB, 1TB | Velocity lessons: U3, V30, A2, Class 10 | Guarantee: 10-year restricted

The Samsung Pro Plus was practically the quickest card we examined by way of sequential write efficiency (round 130 MB/s in CrystalDiskMark) and was a detailed second by way of random learn/write speeds, so it ought to work nice whether or not you’re shopping for for a digicam, Android pill or gaming handheld. Unsurprisingly, it has all of the requisite rankings: U3, V30 and A2. Its sequential learn efficiency (round 165 MB/s) isn’t fairly as fast as a number of the different playing cards beneath, so it isn’t absolutely the quickest for accessing giant information saved in your card, however the distinction is small in real-world use. 

The principle purpose the Professional Plus tops our listing is as a result of it delivers these sturdy speeds at a comparatively reasonably priced value. The cardboard initially began at $19 for 128GB, $30 for 256GB and $60 for 512GB, however previous gross sales have introduced these fashions as little as $11, $18 and $29, respectively. When it’s that low cost, the Professional Plus makes most competing microSD playing cards redundant. Samsung additionally sells the cardboard with a USB reader that’ll assist it attain its most speeds for just a few {dollars} extra. For those who want extra space, there’s also a 1TB model that needs to be simply as quick, although that one is at the moment rather more costly at $110. Both method, the cardboard comes with a 10-year restricted guarantee.

For those who decide to purchase the Professional Plus, ensure you get the latest-generation mannequin. Samsung continues to be promoting the prior iteration of the Professional Plus, which seems to be an identical however isn’t as fast. As an alternative, go for the one with sequential learn speeds rated at 180 MB/s and sequential write speeds rated at 130 MB/s. We examined the 256GB model of the newer Professional Plus attributable to inventory points with the 128GB mannequin on the time of testing, however this shouldn’t have a serious impression on real-world efficiency, as Samsung charges each playing cards identically. 

Execs

• Constantly fast sequential and random learn/write efficiency
• Nice worth
• Available at trusted retailers
• Has a 1TB choice

Cons

• Some friends have barely sooner sequential learn speeds

The Samsung Pro Ultimate is a step-up mannequin in Samsung’s microSD lineup and, as anticipated, it’s a bit of bit sooner than the Professional Plus throughout the board. Its greatest positive aspects are in sequential learn speeds, which have been the quickest we examined and averaged near Samsung’s marketed charge charge of 200 MB/s throughout our varied benchmarks. You’ll want to purchase the cardboard with Samsung’s USB reader to attain that efficiency, however that could possibly be value it if you happen to usually transfer information out of your microSD card to a PC. The Professional Final technically led the pack when it got here to sequential write and random learn/write speeds as nicely, although the margins there are a lot much less important in comparison with the Professional Plus and the opposite high UHS-I playing cards we examined.

The principle query is value. For those who see the Professional Final accessible for a similar value because the Professional Plus, you would possibly as nicely seize it as a substitute. It comes with the identical 10-year guarantee and needs to be equally sturdy. Previous reductions have introduced the 128GB, 256GB and 512GB fashions as little as $15, $25 and $45, respectively; that is nonetheless reasonably priced, however the Professional Plus will nearly at all times be a bit of bit cheaper — and thus a greater worth for many wants, particularly at larger capacities. There is no 1TB choice right here, both. 

Execs

• Quickest microSD card we examined (with applicable USB reader)
• Simply accessible at trusted retailers

Cons

• Professional Plus is best worth for many
• No 1TB mannequin

If the Samsung Professional Plus ever jumps too excessive in value or turns into unavailable, the Kingston Canvas Go Plus is one other sturdy various. This can be a U3-, V30- and A2-rated card backed by a lifetime restricted guarantee. Its sequential learn speeds trailed solely the Samsung Professional Final throughout CrystalDiskMark, ATTO and the BlackMagic Disk Velocity Take a look at. It successfully tied with SanDisk’s Excessive and Nintendo Swap-branded playing cards in our giant file switch speeds take a look at. Sequential write speeds (simply over 100 MB/s on CrystalDiskMark) are the place it lags behind the Professional Plus, however they need to nonetheless be fast sufficient for a lot of makes use of. Its random learn/write speeds have been solely bested by Samsung’s Professional playing cards in benchmarks, so it’s nonetheless a superb choice for apps and video games. The 1TB model can also be $20 cheaper than the equal Professional Plus, so it needs to be an honest worth if you happen to want a number of area and wish to save money. However the different fashions are laborious to justify if you happen to see them hovering in the identical value vary as our picks above.

Execs

• Quicker sequential write speeds than Professional Plus for a (usually) cheaper price than Professional Final
• Lifetime restricted guarantee
• Has a 1TB choice

Cons

• Professional Plus is often a greater worth for many
• Slower sequential write speeds than picks above

The Samsung Evo Select is a transparent step behind our high picks, significantly on the subject of sequential write speeds (just below 70 MB/s on CrystalDiskMark), so it’s not best for cameras. Nonetheless, it’s completely usable for a lot of use circumstances — a Nintendo Swap, for example — and we have beforehand seen its 128GB, 256GB and 512GB fashions fall as little as $10, $14 and $25, respectively. All of these are about on par with the SanDisk Ultra, an oft-recommended cheapo card, regardless of the Evo Choose having larger V30, U3 and A2 rankings. Whereas the Professional Plus has come near these costs, the Evo Choose nearly at all times retails for much less.

Just like the Professional Plus, now you can discover two variations of the Evo Choose: a “customary” mannequin with sequential learn speeds rated at 130 MB/s, and a “new generation” model that bumps that spec as much as 160 MB/s. For the reason that level of this suggestion is to provide you a card that performs nicely sufficient for as little as potential, it is best to get whichever one is cheaper within the capability you need. The brand new mannequin did certainly ship these improved reads in our benchmarks, but it surely performs nearly identically in any other case, so you will not lose a lot by saving a couple of bucks with the older technology. 

The one huge distinction is that the up to date mannequin is the one one accessible in a 1TB capacity; we have not examined that particular mannequin, however at $80-ish it needs to be value a glance if pricing is your solely concern. 

Execs

• Typically accessible for cheaper price than Professional Plus
• Strong efficiency if you happen to simply need a suitable card for reasonable
• Has a 1TB choice

Cons

• Slower than picks above, significantly in sequential write and random efficiency benchmarks

Different notable microSD playing cards

Delkin Gadgets Energy

We didn’t use it ourselves, however if you happen to’re prepared to pay for a extra highly effective UHS-II card constructed for heavy-duty video recording, the Delkin Devices Power has tested well elsewhere and will ship considerably sooner sequential write speeds than our picks above. It’s one of many few UHS-II playing cards we might truly discover in inventory, but it surely prices a ton, with a 128GB mannequin usually priced round $90.

SanDisk Excessive

The SanDisk Extreme successfully matched the Professional Plus in just a few of our sequential write checks and delivered sequential reads about on par with the Canvas Go Plus, however that was partly attributable to us solely with the ability to safe the cardboard’s 256GB mannequin, which is higher-rated than the 128GB model. It’s a high-quality selection if you happen to see it on sale at a good vendor, however its random efficiency lagged behind the Samsung Professional and Kingston playing cards, and it typically prices extra.

SanDisk microSDXC Card for Nintendo Swap

The SanDisk microSDXC Card for Nintendo Switch is one other first rate choice if you happen to ever see it accessible for lower than the Professional Plus and Canvas Go Plus. Its sequential learn speeds have been about the identical because the latter in our benchmarks, however its sequential writes have been barely slower (and farther behind the Professional Plus). Its random learn/writes have been a bit behind in accordance with CrystalDiskMark as nicely, and it is typically priced larger than our high decide. SanDisk backs the cardboard with a lifetime guarantee, nevertheless, plus it’s accessible in a 1TB capacity. Observe that we examined the Apex Legends model of the 128GB card; SanDisk additionally sells a Super Mario model, however we will not say if that one performs any in another way.

Lexar Skilled 1066x

Equally, the Lexar Professional 1066x is an honest various to the Professional Plus if our most important picks are unavailable. It’s one other V30, U3 and A2 mannequin, and like Samsung’s card, its sequential write speeds have been a bit sooner than the Canvas Go Plus and SanDisk Swap card in our benchmarks. These write speeds weren’t as fast because the Professional Plus, and its sequential reads trailed all three playing cards. Random learn/writes additionally lagged behind the Professional Plus and Canvas Go Plus, and we observed its speeds peak and dip extra noticeably in our file switch take a look at. Nonetheless, it’s not sluggish, so relying on its value, it could be a superb cut price if you happen to want quick write speeds for video recording and the like. It’s additionally available in 1TB, plus it comes with a lifetime restricted guarantee.

SanDisk Excessive Professional

The SanDisk Extreme Pro is a rival to the Samsung Professional Final however, as of this writing, is both unavailable at most trusted retailers or priced too excessive by comparability.

PNY Elite-X

The PNY Elite-X typically goes for reasonable and wasn’t too far off the random learn/write efficiency of Samsung’s Professional playing cards in CrystalDiskMark, but it surely was nicely behind in our sequential checks.
