海外TECH	Engadget	The best microSD cards in 2024	https://www.engadget.com/computing/accessories/best-microsd-card-130038282.html?src=rss	Most microSD cards are fast enough for boosting storage space and making simple file transfers but some provide a little more value than others If you ve got a device that still accepts microSD cards ーwhether it s a gaming handheld a dash cam a drone or an Android tablet ーwe ve scoured the market and put more than a dozen top contenders through a number of benchmark tests You can find our top recommendations below alongside some general shopping advice before you grab one What to look for in a microSD card Capacity The first thing to figure out when buying a microSD card is how much storage space you need Modern cards are usually available in sizes ranging from GB to GB while an increasing number are available in TB as well TB cards from reputable manufacturers are getting closer but aren t widely available just yet For most a GB or GB model should be the sweet spot between price and storage space But if you need more room ーsay for stashing a bunch of games on a Steam Deck ーa GB or greater card could make more sense and often provides a better cost per GB ratio These days you can find a decent GB card for around or less a good GB card for less than and a solid GB card for less than though many cost closer to or There s a starker increase when you go up to TB cards which typically cost closer to Note that a microSD card s performance may differ depending on what capacity you buy SanDisk says its GB Extreme card delivers sequential write speeds up to MB s for example while the higher capacity models in the same line offer up to MB s When we talk about microSD cards today we usually refer to cards that use the microSDXC eXtended Capacity standard which have a capacity between GB and TB Your device needs to support this for it to work with a microSDXC card This will almost never be an issue these days but some older devices a Nintendo DS for instance are only compatible with microSDHC High Capacity cards which range from GB to GB Read and write speeds MicroSD cards are primarily judged on their read and write speeds which are usually measured in megabytes per second MB s Generally most microSD cards have faster read speeds than write speeds These metrics can then be broken down into sequential and random performance Sequential read and write speeds matter when you re trying to access or save long constant streams of data such as opening a large video or copying a big batch of files from a PC If you want to use a microSD card for media storage this is particularly important Random performance meanwhile is about how quickly a card can read and write small files scattered throughout the device Since random read write speeds are much lower than sequential ones storage device makers tend not to advertise them as loudly But they re important if you use a card with a gaming device or a single board computer like the Raspberry Pi where it often has to rapidly save and access small bits of data in random locations SD Association Speed ratings If you look at a microSD card you ll see a buffet of numbers letters and symbols Most of these refer to the card s speed class and performance ratings which are determined by the SD Association A card s Video Speed Class or V rating details its minimum sequential write speed which is especially important when recording video from a camera It ranges from V to V Most of the cards we tested had a V rating so they have a sequential write speed of at least MB s This should be enough to support up to K video at lower bitrates Higher rated V and V cards are usually better for capturing K but they come at a much higher cost The UHS Speed Class or U rating also refers to a card s minimum sequential write speed It comes in two varieties U which mandates a minimum of MB s and U which is rated for MB s The older Speed Class rating overlaps with the other two systems It s signified by a C symbol and goes from Class to Class with the number again indicating minimum sequential write speed This rating is less relevant nowadays but you may still see a C logo on some cards The Application Performance spec marked by an A symbol is an indicator of random read write speeds This is measured in IOPS or input output operations per second rather than MB s There are two categories here A cards offer a minimum random read speed of IOPS and a minimum random write speed of IOPS while A cards bump those up to IOPS and IOPS respectively Both ratings also guarantee sequential write speeds of at least MB s To keep it simple most people should look for a card with V U and A ratings It s totally possible to get a solid card without those A U card might be worth it if you just need a cheap high capacity option for example V and V cards are worth a look if you re serious about shooting high resolution photos and video as well But overall cards with the certifications above should provide the best blend of price and performance today It s important to emphasize that these ratings are baselines Most V cards offer significantly higher write speeds than MB s for instance and some A cards can outperform some A models in practice The speeds advertised by manufacturers aren t always percent accurate either Sometimes the card will be slower in real world use other times it may actually be a bit faster UHS bus speeds The other spec to note is the card s bus interface Most microSD cards available today are UHS I which have a theoretical maximum speed of MB s There are also UHS II cards which have an extra row of pins on the back and can reach up to MB s A UHS III standard exists as well but hasn t seen wide adoption These are labeled on the card with a Roman numeral I or II The fastest microSD cards you can buy right now are UHS II cards and they re usually the ones with V or V ratings If you shoot lots of K to K video or frequently use burst mode to capture ultra high res photos the performance gains of a good UHS II card can save you time But these are much more expensive than UHS I cards This GB Lexar Professional Gold model for instance is a relative bargain at While that s less than many UHS II models we ve seen in the past it s still more than double the typical price of our top pick mentioned below You need a device that s compatible with the UHS II interface to see any benefits too and stock for UHS II cards is generally spottier For now the higher speeds aren t worth the price premium for most people so we stuck mostly to UHS I cards here We ll also note Samsung s announcement earlier this year of a new GB microSD card based on an entirely different standard called SD Express This is theoretically much faster than any UHS I or UHS II option Samsung claims this specific model can reach sequential read speeds up to a whopping MB s For context that d be quicker than some older SSDs SD Express has technically been around for several years but hasn t seen wide adoption so exactly how this card performs in reality ーand how much it ll cost ーremains to be seen We ll test the device once it becomes available which Samsung says will be sometime later in Kris Naudus Engadget A note on card readers the Nintendo Switch and Steam Deck While the UHS I spec has a theoretical maximum of MB s some UHS I cards can exceed that speed through proprietary extensions You need a compatible card reader and host device to take advantage of that extra performance though If you find a UHS I card advertising speeds higher than MB s this is what s going on You can see these limits in action with a Nintendo Switch or Steam Deck Both of those gaming devices support the UHS I interface and don t go beyond its official speed flattening any sequential gains some cards may have elsewhere The broader takeaway Your microSD card will only be as fast as the slowest link in your chain Warranty Many microSD cards are designed to be durable with protection from water extreme temperatures X rays and drops Still in case of catastrophe a long warranty is always good to have Many manufacturers offer lifetime or year limited warranties though we ve noticed that endurance cards marketed to withstand more hours of writing are usually covered for a shorter period of time For example Samsung s Pro Endurance a model aimed at security cameras and other monitoring devices comes with a five year warranty Avoiding counterfeits The memory card market has had a particular problem with scammers selling fake products To guard against this only buy from a known brand and a reputable retailer such as Best Buy B amp H Photo or Adorama If you shop at Amazon only buy if the shipper and seller is Amazon com Though a handful of users have reported receiving counterfeits even from Amazon directly in the past Remember If a price seems too good to be true it probably is Be wary of any retailer offering significantly a lower price than others Once you receive a card check its packaging for any irregularities You can run benchmark tests like CrystalDiskMark or BlackMagic Disk Speed Test to verify its speeds aren t drastically lower than what s advertised or possible given its specs You can also use software that s designed to verify the true capacity and performance of your card such as Htestw and FakeFlashTest How we tested We put microSD cards through a series of tests to verify their sequential and random performance These included benchmarks like CrystalDiskMark BlackMagic Disk Speed Test ATTO Disk Benchmark and AJA System Test as well as a few real world tests We copied and pasted a small folder of photos about GB in size to and from each card then did the same with a larger GB folder containing multiple file types and subfolders timing the process each time We also checked how each card performed on the Steam Deck downloading games of varying sizes ーincluding Stardew Valley Aperture Desk Job Metal Gear Rising Revengeance and Apex Legends nbsp ーthen timing how long it took to launch each game and load save files We used a Kingston USB UHS II reader to test each card on both Windows and macOS Sonoma For the former we used an Alienware gaming PC with an Intel Core i F Nvidia GeForce RTX GPU GB of RAM and a TB SSD For the latter we used a inch MacBook Pro with an Apple M Pro chip GB of RAM and a GB SSD To use our card reader on the MacBook we used Apple s USB C Digital AV Multiport Adapter We tested the GB version of each card wherever possible though for a few cards ーSanDisk s Extreme and Samsung s Pro Plus and Pro Ultimate ーwe were only able to test their GB models We also reformatted each card before testing with the SD Association s Memory Card Formatter tool Best microSD cards of Other notable microSD cards The SanDisk Extreme and PNY Elite X Photo by Jeff Dunn Engadget Delkin Devices Power We didn t use it ourselves but if you re willing to pay for a more powerful UHS II card built for heavy duty video recording the Delkin Devices Power has tested well elsewhere and should deliver significantly faster sequential write speeds than our picks above It s one of the few UHS II cards we could actually find in stock but it costs a ton with a GB model normally priced around SanDisk Extreme The SanDisk Extreme effectively matched the Pro Plus in a few of our sequential write tests and delivered sequential reads about on par with the Canvas Go Plus but that was partly due to us only being able to secure the card s GB model which is higher rated than the GB version It s a fine choice if you see it on sale at a reputable seller but its random performance lagged behind the Samsung Pro and Kingston cards and it often costs more SanDisk s Nintendo Switch branded microSDXC card Photo by Jeff Dunn Engadget SanDisk microSDXC Card for Nintendo Switch The SanDisk microSDXC Card for Nintendo Switch is another decent option if you ever see it available for less than the Pro Plus and Canvas Go Plus Its sequential read speeds were about the same as the latter in our benchmarks but its sequential writes were slightly slower and farther behind the Pro Plus Its random read writes were a bit behind according to CrystalDiskMark as well and it s often priced higher than our top pick SanDisk backs the card with a lifetime warranty however plus it s available in a TB capacity Note that we tested the Apex Legends version of the GB card SanDisk also sells a Super Mario model but we can t say if that one performs any differently Lexar Professional x Similarly the Lexar Professional x is a decent alternative to the Pro Plus if our main picks are unavailable It s another V U and A model and like Samsung s card its sequential write speeds were a bit faster than the Canvas Go Plus and SanDisk Switch card in our benchmarks Those write speeds weren t as quick as the Pro Plus and its sequential reads trailed all three cards Random read writes also lagged behind the Pro Plus and Canvas Go Plus and we noticed its speeds peak and dip more noticeably in our file transfer test Still it s not slow so depending on its price it might be a good bargain if you need fast write speeds for video recording and the like It s also available in TB plus it comes with a lifetime limited warranty SanDisk Extreme Pro The SanDisk Extreme Pro is a rival to the Samsung Pro Ultimate but as of this writing is either unavailable at most trusted retailers or priced too high by comparison PNY Elite X The PNY Elite X often goes for cheap and wasn t too far off the random read write performance of Samsung s Pro cards in CrystalDiskMark but it was well behind in our sequential tests Recent updates November We ve checked back with this guide to ensure our recommendations are still accurate and made light edits for clarity nbsp August We ve updated this guide to note the recently released TB models for three of our top picks the Samsung Pro Plus the Kingston Canvas Go Plus and the Samsung Evo Select We ve also made sure all pricing details are as up to date as they can be nbsp This article originally appeared on Engadget at	2024-11-07 10:01:28
