If you wish to add space for storing to a Nintendo Change, GoPro or Raspberry Pi, you want a microSD card. However whereas a number of playing cards can be quick sufficient for storing images, transferring information and the like, some cheap choices will carry out higher than others. We lately put greater than a dozen fashions via a spread of benchmark checks that will help you discover the very best microSD playing cards to your knowledge storage wants.
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 area you want. Fashionable playing cards are often accessible in sizes starting from 32GB to 512GB, whereas a handful supply 1TB fashions as nicely. 2TB playing cards are theoretically doable however nonetheless within the prototype stage.
For many, a 128GB or 256GB mannequin must be the candy spot between value and capability. However if you happen to want extra room — say, for stashing a bunch of video games on a Steam Deck — a 512GB card might make extra sense and sometimes offers a greater cost-per-GB ratio. Today, yow will discover an honest 128GB card for round $15 or much less, an honest 256GB card for lower than $30 and (with gross sales) an honest 512GB card could possibly be as little as $40 (although most value nearer to $50 or $60). There’s a starker enhance once you go as much as 1TB playing cards, which usually value round $100.
Be aware {that a} microSD card’s efficiency could differ relying on what capability you purchase. SanDisk says its 128GB Excessive card delivers sequential write speeds as much as 90 MB/s, for instance, whereas the higher-capacity fashions in the identical line supply as much as 130 MB/s.
After we discuss microSD playing cards immediately, we often discuss with playing cards that use the microSDXC (eXtended Capability) customary, which have a capability between 32GB and 2TB. Your machine must help this for it to work with a microSDXC card. It will nearly by no means be a difficulty nowadays, however some older units (a Nintendo 3DS as an illustration) 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). Usually talking, most microSD playing cards have quicker learn speeds than write speeds. These metrics can then be damaged down into sequential and random efficiency. Sequential learn and write speeds matter once you’re making an attempt 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 necessary.
Random efficiency, in the meantime, is about how shortly a card can learn and write small information scattered all through the machine. Since random learn/write speeds are a lot decrease than sequential ones, storage machine makers have a tendency to not promote them as loudly. However they’re necessary if you happen to use a card with a gaming machine or a single-board laptop just like the Raspberry Pi, the place it usually has to quickly save and entry small bits of information in random areas.
Pace scores
When you take a look at a microSD card, you’ll see a buffet of numbers, letters and symbols. Most of those discuss with the cardboard’s velocity class and efficiency scores, that are decided by the SD Affiliation.
A card’s Video Pace Class, or V-rating, particulars its minimal sequential write velocity, which is particularly necessary when recording video from a digital camera. It ranges from V6 to V90. A lot of the playing cards we examined had a V30 ranking, in order that they have a sequential write velocity of at the very least 30 MB/s. This must be sufficient to help as much as 4K video at decrease bitrates. Larger-rated V60 and V90 playing cards are often higher for capturing 8K, however they arrive at a a lot larger value.
The usSpeed 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 Pace Class ranking overlaps with the opposite two techniques. 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 ranking is much less related these days, however you should still see a “C10” emblem on some playing cards.
The Software Efficiency spec, marked by an An emblem, is an indicator of random learn/write speeds. That is measured in IOPS, or enter/output operations per second, slightly than MB/s. There are two classes right here: A1 playing cards supply 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 pair of,000 IOPS, respectively. Each scores additionally assure sequential write speeds of at the very least 10 MB/s.
Most individuals ought to search for a card with V30, U3 and A2 scores. It’s completely doable to get a strong card with out these: A U1 card may be value it if you happen to simply want an inexpensive possibility with a excessive capability to carry information, for instance. V60 and V90 playing cards are value a glance if you happen to’re severe about capturing high-resolution images and video as nicely. However typically talking, playing cards with the certifications above ought to present the very best mix of value and efficiency immediately.
It’s necessary to emphasise that these scores are baselines. Many V30 playing cards supply considerably larger write speeds than 30 MB/s, as an illustration, and a few A1 playing cards can outperform some A2 fashions in apply. The speeds marketed by producers aren’t all the time 100 % correct, both: Typically the cardboard can be slower in real-world use, different instances it might truly be a bit quicker.
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 more recent UHS-III customary exists as nicely however hasn’t seen large adoption simply but.) These are labeled on the cardboard with a Roman numeral I or II.
Absolutely the quickest microSD playing cards proper now are UHS-II playing cards, they usually’re often those with V60 or V90 scores. When you shoot plenty of 4K to 8K video or continuously use burst mode to seize extremely high-res images, the efficiency features of UHS-II card can prevent time.
However these are rather more costly than UHS-I playing cards: This 128GB mannequin from ProGrade Digital, for instance, is a relative cut price at $55. You want a tool that’s appropriate with the united statesII interface to see any advantages, too, and as we have been placing this information collectively, inventory for UHS-II playing cards was spotty. For now, the upper speeds aren’t definitely worth the value premium for the overwhelming majority of individuals, so we principally caught to UHS-I choices.
A be aware on card readers, the Nintendo Change and Steam Deck
Whereas the united statesI 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 machine to benefit from that additional efficiency, although. When you discover a UHS-I card promoting speeds larger than 104 MB/s, that is what’s happening. You’ll be able to see these limits in motion with a Nintendo Change or Steam Deck: Each of these gaming units help the united statesI interface and don’t transcend its official velocity, flattening any sequential features some playing cards could 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 all the time good to have. Many producers supply lifetime restricted warranties, although we’ve observed that “endurance” playing cards marketed to resist extra hours of writing are often coated for a a lot shorter time frame.
Avoiding counterfeits
The reminiscence card market has had a selected downside 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. When you 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 prior to now.) Keep in mind: If a value appears too good to be true, it in all probability 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’ll be able to run benchmark checks like CrystalDiskMark or BlackMagic Disk Pace Take a look at to confirm its speeds aren’t drastically decrease than what’s marketed (or doable, given its specs). You can even 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 12 microSD playing cards via a collection of checks to confirm their sequential and random efficiency. These included benchmarks like CrystalDiskMark, BlackMagic Disk Pace Take a look at, ATTO Disk Benchmark and AJA System Take a look at, in addition to a couple of “real-world” checks. We copied and pasted a small folder of images 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, Steel Gear Rising: Revengeance and Apex Legends — then timing how lengthy it took to launch every sport 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 doable, although for a couple of playing cards — SanDisk’s Excessive and Samsung’s Professional Plus and Professional Final — we have been solely capable of check their 256GB fashions. We additionally reformatted every card earlier than testing with the SD Affiliation’s Reminiscence Card Formatter software.
Greatest for many: Samsung Professional Plus
The Samsung Professional Plus was almost 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 digital camera, pill or gaming handheld. Unsurprisingly, it has all of the requisite scores: U3, V30 and A2. Its sequential learn efficiency (round 165 MB/s) isn’t fairly as fast as a few of our alternate picks under, however it’s not far behind.
The principle motive the Professional Plus tops our checklist 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 latest gross sales have introduced these fashions as little as $12, $20 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 a couple of {dollars} extra. Both method, the cardboard comes with a 10-year restricted guarantee.
When you decide to purchase the Professional Plus, ensure you get the latest-generation mannequin, which Samsung launched in April 2023. For the time being, the corporate continues to be promoting the prior iteration of the Professional Plus, which seems to be an identical however isn’t as fast, particularly in relation to random learn/write speeds. (Search for the mannequin 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 Professional Plus as a consequence of inventory points with the 128GB mannequin on the time of testing, however this shouldn’t have a serious affect on real-world efficiency, as Samsung charges each playing cards identically.
A quicker possibility: Samsung Professional Final
The Samsung Professional Final is a brand new step-up mannequin in Samsung’s microSD lineup and, as anticipated, it’s slightly bit quicker than the Professional Plus throughout the board. Its largest features are in sequential reads, which have been the quickest we examined and averaged near Samsung’s marketed velocity of 200 MB/s throughout our varied benchmarks. You’ll want to purchase the cardboard with Samsung’s USB reader to realize that efficiency, however that could possibly be value it if you happen to often 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 vital in comparison with the Professional Plus and the opposite prime UHS-I playing cards we examined.
The principle query is value. When you 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 must 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 all the time be slightly bit cheaper — and thus a greater worth for many wants, particularly at larger capacities.
One other good possibility: Kingston Canvas Go Plus
If the Samsung Professional Plus ever turns into unavailable, the Kingston Canvas Go Plus is one other sturdy various. It is 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 Pace Take a look at. It successfully tied with SanDisk’s Excessive and Nintendo Change-branded playing cards in our massive file switch check. Its 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 too, so it’s nonetheless possibility for apps and video games. However it’s arduous to justify if you happen to see it priced larger than the Professional Plus or Final.
Greatest worth: Samsung Evo Choose
The Samsung Evo Choose is a transparent step behind our prime picks, significantly in relation to sequential write speeds (slightly below 70 MB/s on CrystalDiskMark), so it’s not ultimate for cameras. Nonetheless, it’s completely usable for a lot of use instances — a Nintendo Change, as an illustration — and we have seen its 128GB, 256GB and 512GB fashions fall as little as $11, $17 and $29, respectively, prior to now. All of these are about on par with the SanDisk Extremely, a continuously advisable cheapo card, regardless of the Evo Choose having larger V30, U3 and A2 scores. The 512GB variant is a very nice cut price if you happen to simply want a piece of area on a budget. (The Extremely is on the market with a large 1.5TB capability, although.) Whereas the Professional Plus has beforehand hit these costs, the Evo Choose tends to sit down there extra often.
Different microSD card choices
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 Units Energy has examined nicely elsewhere and may ship considerably quicker sequential write speeds than our picks above. It’s one of many few UHS-II playing cards we might truly discover in inventory, however it prices a ton, with a 64GB mannequin usually priced at $90.
The SanDisk microSDXC Card for Nintendo Change is one other worthwhile possibility 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 response to CrystalDiskMark as nicely. The 128GB model of this card is often priced slightly below $20, however the 512GB model usually goes for about $10 lower than the Canvas Go Plus. SanDisk backs the cardboard with a lifetime guarantee too, plus it’s accessible in a 1TB capability. Be aware that we examined the Apex Legends model of the 128GB card; SanDisk additionally sells a Tremendous Mario mannequin, however we are able to’t communicate as to whether that one performs any otherwise.
Equally, the Lexar Skilled 1066x is an honest various to the Professional Plus if our 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 quicker than the Canvas Go Plus and SanDisk Change card in our benchmarks. These write speeds weren’t as fast as 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 check. Nonetheless, it’s not gradual, so relying on its value, it may be cut price if you happen to want higher write speeds than the Kingston card provides (for video recording, and many others.). It additionally comes with a lifetime restricted guarantee.
The SanDisk Excessive successfully matched the Professional Plus in a couple of of our sequential write checks and delivered sequential reads about on par with the Canvas Go Plus, however that was partly as a consequence of us solely having the ability to safe the cardboard’s 256GB mannequin, which is higher-rated than the 128GB model. Its random efficiency lagged behind the Samsung Professional and Kingston playing cards as nicely, and it usually prices extra. When you see it on sale from a good vendor, although, it’s one other high quality card. It’s additionally accessible with 1TB of area. The SanDisk Excessive Professional, in the meantime, is a rival to the Samsung Professional Final however is both unavailable at most trusted retailers or priced too excessive by comparability.
The PNY Elite-X wasn’t too far off the random learn/write efficiency of the Professional Plus and Professional Final in CrystalDiskMark, and it usually goes for reasonable, however it was nicely behind in our sequential checks.
