The very best microSD playing cards in 2024

Most microSD playing cards are quick sufficient for storing and transferring information, however some will present slightly extra bang for the buck than others. When you’ve obtained a tool that helps the format — be it a Nintendo Switch or different gaming handheld, a GoPro, a Raspberry Pi or a touch cam — we’ve researched the market and put greater than a dozen prime microSD playing cards by means of a bunch of benchmark assessments. You will discover the playing cards that stood out probably the most under, alongside some common issues to know before you purchase.

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 space for storing you want. Trendy playing cards are normally accessible in sizes starting from 32GB to 512GB, whereas an rising 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 must be the candy spot between worth and space for storing. However for those who want extra room — say, for stashing a bunch of video games on a Steam Deck — a 512GB or larger card might make extra sense and sometimes offers a greater cost-per-GB ratio. As of late, you will discover a good 128GB card for round $15 or much less, a very good 256GB card for lower than $30 and a strong 512GB card for lower than $40 (although many price nearer to $50 or $60). There’s a starker improve whenever you go as much as 1TB playing cards, which generally price nearer to $100.

Be aware {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 speak about microSD playing cards right this moment, we normally consult with playing cards that use the microSDXC (eXtended Capacity) standard, which have a capability between 32GB and 2TB. Your machine must assist this for it to work with a microSDXC card. This may virtually by no means be a difficulty nowadays, however some older units (a Nintendo 3DS, as an example) are solely suitable 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 normally measured in megabytes per second (MB/s). Usually, 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 whenever you’re attempting to entry or save lengthy, fixed streams of knowledge, resembling opening a big video or copying a giant 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 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 essential for those who use a card with a gaming machine or a single-board pc just like the Raspberry Pi, the place it usually has to quickly save and entry small bits of knowledge in random areas.

Velocity scores

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

A card’s Video Velocity Class, or V-rating, particulars its minimal sequential write pace, which is particularly essential when recording video from a digital camera. 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 pace of no less than 30 MB/s. This must be sufficient to assist as much as 4K video at decrease bitrates. Greater-rated V60 and V90 playing cards are normally higher for capturing 8K, however they arrive at a a lot greater price.

The UHS Velocity Class, or U-rating, additionally refers to a card’s minimal sequential write pace. 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 programs. It’s signified by a C image and goes from Class 2 to Class 10, with the quantity (once more) indicating minimal sequential write pace. This score is much less related these days, however you should still see a “C10” emblem on some playing cards.

The Utility 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 provide a minimal random learn pace of 1,500 IOPS and a minimal random write pace of 500 IOPS, whereas A2 playing cards bump these as much as 4,000 IOPS and a couple of,000 IOPS, respectively. Each scores 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 scores. It’s completely doable to get a strong card with out these: A U1 card may be price it for those who simply want an affordable, high-capacity choice, for instance. V60 and V90 playing cards are price a glance for those who’re severe about taking pictures high-resolution images and video as nicely. However total, playing cards with the certifications above ought to present the most effective mix of worth and efficiency right this moment.

It’s essential to emphasise that these scores are baselines. Most V30 playing cards provide considerably greater write speeds than 30 MB/s, as an example, and a few A1 playing cards can outperform some A2 fashions in observe. The speeds marketed by producers aren’t all the time one hundred pc correct, both: Typically the cardboard will probably be slower in real-world use, different instances 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 right this moment are UHS-I, which have a theoretical most pace 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 commonplace exists as nicely however hasn’t seen extensive adoption.) These are labeled on the cardboard with a Roman numeral I or II.

The quickest microSD playing cards you should purchase proper now are UHS-II playing cards, they usually’re normally those with V60 or V90 scores. When you shoot plenty of 4K to 8K video or incessantly use burst mode to seize extremely high-res images, the efficiency positive aspects of a very good UHS-II card can prevent time.

However these are rather more costly than UHS-I playing cards: This 128GB Lexar Professional Gold mannequin, as an 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 everyday worth of our prime choose talked about under. You want a tool that’s suitable 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 definitely worth the worth premium for most individuals, so we caught largely to UHS-I playing cards right here.

We’ll additionally notice Samsung’s announcement earlier this 12 months of a brand new 256GB microSD card based mostly on a wholly completely different commonplace referred to as SD Specific. 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 Specific has technically been around for a number of years however hasn’t seen extensive adoption, so precisely how this card performs in actuality — and the way a lot it’ll price — stays to be seen. We’ll check the machine as soon as it turns into accessible, which Samsung says will probably be someday later in 2024.

A notice on card readers, the Nintendo Change and Steam Deck

Whereas the UHS-I spec has a theoretical most of 104 MB/s, some UHS-I playing cards can exceed that pace by means of proprietary extensions. You want a suitable card reader and host machine to benefit from that additional efficiency, although. When you discover a UHS-I card promoting speeds greater 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: Both of those gaming units assist the UHS-I interface and don’t transcend its official pace, 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 all the time good to have. Many producers provide lifetime or 10-year restricted warranties, although we’ve seen that “endurance” playing cards marketed to face up to extra hours of writing are normally lined for a shorter time period. For instance, Samsung’s Pro Endurance, a mannequin aimed toward safety cameras and different monitoring units, comes with a five-year guarantee.

Avoiding counterfeits

The reminiscence card market has had a selected downside with scammers promoting faux merchandise. To protect in opposition to this, solely purchase from a identified model and a good retailer resembling Greatest Purchase, B&H Picture 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 instantly up to now.) Bear in mind: If a worth appears too good to be true, it in all probability is. Be cautious of any retailer providing considerably a lower cost than others.

When you obtain a card, test its packaging for any irregularities. You’ll be able to run benchmark assessments like CrystalDiskMark or BlackMagic Disk Speed Test to confirm its speeds aren’t drastically decrease than what’s marketed (or doable, given its specs). You may also use software program that’s designed to confirm the true capability and efficiency of your card, resembling H2testw and FakeFlashTest.

How we examined

We put 13 microSD playing cards by means of a sequence of assessments 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 a couple of “real-world” assessments. We copied and pasted a small folder of images about 1.15GB in dimension to and from every card, then did the identical with a bigger 12.2GB folder containing a number of file sorts 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 doable, although for a couple of playing cards — SanDisk’s Excessive and Samsung’s Professional Plus and Professional Final — we had been solely capable of check their 256GB fashions. We additionally reformatted every card earlier than testing with the SD Affiliation’s Memory Card Formatter tool.

The Samsung Pro Plus was almost the quickest card we examined when it comes to sequential write efficiency (round 130 MB/s in CrystalDiskMark) and was an in depth second when it comes to random learn/write speeds, so it ought to work nice whether or not you’re shopping for for a digital camera, Android 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 number of the different playing cards under, so it isn’t absolutely the quickest for accessing massive information saved in your card, however the distinction is small in real-world use. 

The principle cause the Professional Plus tops our listing is as a result of it delivers these robust speeds at a comparatively reasonably priced worth. 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 a couple of {dollars} extra. When you want more room, the corporate recently released a brand new 1TB model that must be simply as quick, although that one is presently rather more costly at $120. Both approach, the cardboard comes with a 10-year restricted guarantee.

When you decide to purchase the Professional Plus, ensure you get the latest-generation mannequin. Samsung remains to be promoting the prior iteration of the Professional Plus, which seems to be similar 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 significant affect 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 slightly bit sooner than the Professional Plus throughout the board. Its greatest positive aspects are in sequential learn speeds, which had 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 realize that efficiency, however that might be price it for those who frequently 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 prime UHS-I playing cards we examined.

The principle query is price. When you see the Professional Final accessible for a similar worth because the Professional Plus, you may as nicely seize it as an alternative. 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 virtually all the time be slightly bit cheaper — and thus a greater worth for many wants, particularly at greater capacities. There is not any 1TB choice right here, both. 

Execs

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

Cons

If the Samsung Professional Plus ever jumps too excessive in worth or turns into unavailable, the Kingston Canvas Go Plus is one other robust 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 Change-branded playing cards in our massive file switch speeds check. 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 had been solely bested by Samsung’s Professional playing cards in benchmarks, so it’s nonetheless a very good choice for apps and video games. The 1TB model can also be $20 cheaper than the equal Professional Plus, so it must be a good worth for those who want plenty of area and need to save money. However the different fashions are arduous to justify for those who see them hovering in the identical worth vary as our picks above.

Execs

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

Cons

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

The Samsung Evo Select is a transparent step behind our prime picks, significantly with regards to sequential write speeds (just below 70 MB/s on CrystalDiskMark), so it’s not supreme for cameras. Nonetheless, it’s completely usable for a lot of use circumstances — a Nintendo Change, as an 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 greater V30, U3 and A2 scores. Whereas the Professional Plus has come near these costs, the Evo Choose virtually all the time retails for much less.

Just like the Professional Plus, now you can discover two variations of the Evo Choose: a “commonplace” 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. Because the level of this suggestion is to provide you a card that performs nicely sufficient for as little as doable, 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, however it 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 massive distinction is that the up to date mannequin is the one one accessible in a 1TB capacity; we’ve not examined that particular mannequin, however at $80 it must be price a glance if pricing is your solely concern. 

Execs

• Usually accessible for lower cost than Professional Plus
• Stable efficiency for those who simply need a suitable card for affordable
• 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 for those who’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, however it prices a ton, with a 128GB mannequin usually priced round $90.

SanDisk Excessive

The SanDisk Extreme successfully matched the Professional Plus in a couple of of our sequential write assessments 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 for those who see it on sale at a good vendor, however its random efficiency lagged behind the Samsung Professional and Kingston playing cards, and it usually prices extra.

SanDisk microSDXC Card for Nintendo Change

The SanDisk microSDXC Card for Nintendo Switch is one other respectable choice for those who ever see it accessible for lower than the Professional Plus and Canvas Go Plus. Its sequential learn speeds had been about the identical because the latter in our benchmarks, however its sequential writes had been barely slower (and farther behind the Professional Plus). Its random learn/writes had been a bit behind in keeping with CrystalDiskMark as nicely, and it is usually priced greater than our prime choose. SanDisk backs the cardboard with a lifetime guarantee, nonetheless, plus it’s accessible in a 1TB capacity. Be aware that we examined the Apex Legends model of the 128GB card; SanDisk additionally sells a Super Mario model, however we won’t say if that one performs any otherwise.

Lexar Skilled 1066x

Equally, the Lexar Professional 1066x is a good various to the Professional Plus if our principal picks are unavailable. It’s one other V30, U3 and A2 mannequin, and like Samsung’s card, its sequential write speeds had been a bit sooner than the Canvas Go Plus and SanDisk Change 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 seen its speeds peak and dip extra noticeably in our file switch check. Nonetheless, it’s not sluggish, so relying on its worth, it may be a very good cut price for those who want quick write speeds for video recording and the like.
