The location of the serial number will vary depending on memory card type and manufacturer. If you have a SanDisk card, take a look at this article, which details the possible location of serial numbers on its storage products. We wrote: "The Lexar Play 1TB is the latest to join the 1TB group but it does so with a whimper rather than a bang. Its rather strange behavior in our real life tests combined with average pricing mean that it misses out on the top spot." Drone operators will also appreciate the fact that it can be operated during extreme weathers and temperatures. Dashcam users may want to consider a memory card with higher endurance like the SanDisk MAX Endurance series which promises to last up to 120,000 hours of recording.

The Sandisk Extreme 1TB is an outlier, a one-of-a-kind, one that will satiate, even temporarily, the thirst for massive storage capacity that a growing audience demands. Professionals that require storage on the go will love the flexibility and the performance of this card; price is likely to be a minor factor in their decision process especially when you factor in the time saved from shuffling lower capacity cards around. Despite being rated faster than the Lexar 1000x, the Lexar Professional 1066x actually uses the slower UHS-I interface. This turns out not to be a big deal, though, as we still measured sequential read speeds of up to 157MB/sec and write speeds of 80MB/sec on our 64GB sample, with the faster 128GB to 512GB versions capable of over 120MB/sec. The Transcend did superbly in its speed tests, excelling the claimed write speed (180MB/s) with a whopping 224MB/s, but falling slightly short on the read speed with 224MB/s. Overall, that makes this card an impressive buy at a reasonable cost. This card is ideal for high resolution, rapid-fire stills photography and 8K video, with 4K and HD video being recorded comfortably, too. For 64GB-1TB: A2 performance is 4000 read IOPS, 2000 write IOPS. For 32GB: A1 performance is 1500 read IOPS, 500 write IOPS. Results may vary based on host device, app type, and other factors.One final thing we need to make clear is that speeds will depend on your microSD card reader. The reader built into your average laptop might not be capable of reading from or writing to the fastest cards at their full speed, and we’ve found huge variations in external readers, even those bundled with high-performance cards. If you’re investing in one of the faster microSD cards, grab the matching adaptor from the same manufacturer, or from a credible manufacturer like Lexar, SanDisk, Kingston or Integral. That goes double for UHS-II cards. What if I’m buying for an action camera or dashcam? In theory, the Micron C200 is the only competitor to the Sandisk Extreme 1TB; the problem is that there are none available anywhere. Clearly there is a supply issue with Micron and we’re not sure why. Two smaller players (Silicon Power and Integral) have confirmed that they will launch 1TB microSDXC cards in 2020 but unlike Sandisk or Micron, they don’t control the production of the memory chip that goes inside the card. The best microSD card that we've tested yet is the Silicon Power A1, it might not be the fastest out there but it is the cheapest 1TB microSD on the market and for most users, it is a good enough choice for general usage. A close second would be the similarly priced Teamgroup Go, which we haven't tested but comes with lifetime warranty and a better performance. How to choose the best microSD card The latest UHS-III standard is faster still, with speeds of up to 624MB/sec in both directions simultaneously, while the SD Express standard takes this up to a staggering 985MB/sec. However, neither standard seems to have taken off yet, either in terms of cards or the readers and devices to support them. Should I always buy the fastest card I can afford? If the memory card you are using is fake, it will report errors and show how much actual data was written and read from the card. In the case above, I used a genuine 16 GB SanDisk Extreme Pro memory card that I retired a while ago and as you can see, the software not only showed zero errors, but also reported an average read and write speed of 70 MB/sec. If you perform a similar test and you see errors, you are dealing with a fake or a failing memory card!

SanDisk Extreme Pro 1 TB microSDXC Memory Card + SD Adapter

On the face of it, the SanDisk Extreme Pro seems overpriced. This U3, V30, UHS-I card is significantly more expensive than the Samsung and Integral competition at most capacities, and when tested on our SanDisk ImageMate Pro card reader it wasn’t any faster, at least on sequential read and write speeds, which were 96MB/sec and 85.4MB/sec respectively. As a result, those hunting for the perfect balance of price and performance don’t need to look any further, and spending just a little more will get you your card bundled with Samsung’s excellent 160MB/sec USB card reader. What more could you want?

UHS Speed Class 3 (U3) designates a performance option designed to support real-time video recording with UHS-enabled host devices. Video Speed Class 30 (V30), sustained video capture rate of 30MB/s, designates a performance option designed to support real-time video recording with UHS-enabled host devices. See www.sdcard.org/consumers/speed. For those looking for an even faster microSDXC card, there’s the Sandisk 1TB Extreme Pro microSDXC card; it is far more expensive but almost doubles the read speeds to 170MBps and is fast enough to record in 8K or for your action camera. You will need a compatible reader to make the most out of it though. Final verdict Reduced Capacity: Another very common issue, where the card will report large capacity to your computer, camera or storage device, when in reality it contains only a very small part of the overall capacity. For example, a 512 GB SD card might show up as 512 GB on your computer, but in reality contain only 16 GB of storage cells. This happens because the microchip (a tiny part of the memory card that is responsible for reporting the total amount of storage available) within the memory card has been reprogrammed to report a different size to the host. Such memory cards are extremely dangerous, because you might never be able to tell that they are fakes until you start filling them up. In this particular case, the first 16 GB of storage might work just fine, but anything past that is going to produce data errors. Counterfeit memory cards with reduced capacities should be avoided the most, because they will most certainly result in data loss. Use case: Like SSD, there are broadly three types of microSD cards. One geared towards value-for-money, one geared towards performance (i.e. how fast) and one geared towards endurance (e.g. drone, dashcam, bodycam etc.). Choosing the right one for your needs will determine your overall experience. Other than the benchmarks, we considered four factors that could help you select the perfect microSD card for your usage.

To give you an example, a digital copy of The Legend of Zelda: Tears of the Kingdom comes in at 16.7GB – that means you'd be able to fit 89 games of that size on a 1.5TB SD card. Most Switch games are much smaller than that too, so if you own lots of smaller eShop titles, you're easily looking at being able to store hundreds of titles on a single card. We tested the Sandisk Extreme 1TB with a microSD card reader, on our Dell Latitude 7490 laptop. However, performance, as always, will depend on what card reader you use. In other words, it’s a steal for smartphone and tablet users or anyone wanting more storage for their Switch, and still a good option for your average DSLR or compact camera. Unless you find the Ultima Pro Premium High Speed even cheaper, buy away.

SD cards are flash memory, which means they have no moving parts and instead rely on electronic chips to store data. While they don’t require power to store data, they can be damaged via water, fire and physical pressure. Some companies offer bespoke 'tough' versions that can withstand these elements, even remaining safe in extreme temperatures, so it's worth looking for those if you're going on an adventure. When it comes to counterfeit memory cards, you will find a number of different types of them out there:

SanDisk Extreme PRO 1TB SDXC Memory Card up to 170MB/s, UHS-1

Our SanDisk Extreme SD UHS-I V3 tests saw write speeds live up to its claims, matching them almost exactly at 71.6MB/s. But as with most other cards on this list, the read speeds leave a bit to be desired, coming in at almost half the claimed speed, 71.6MB/s. All can be forgiven, though, bearing in mind the extremely low cost of these cards, especially while still offering such high capacity to users at up to 256GB sizes. Like the Samsung Pro Endurance card above, it is geared towards continuous read/write use cases; the ability of the card to withstand continuous rewriting, often in harsh conditions, like in an externally-located CCTV camera, or in a dashcam glued to a windscreen, baked by a scorching sun. Get faster app performance for an outstanding smartphone experience thanks to the SanDisk Extreme® microSD card’s A2 Specification. Micron says that it will suit 5G, AI and internet of things as well as data storage at the edge. You will be able to record up to five years worth of video recording and Micron says, it should be able to capture "concurrent 4K video recording and up to eight AI events every second." Comparison based on internal testing of SanDisk Extreme® microSDXC™ UHS-l card, versus current UHS-l cards with 100MB/s stated performance. Results may vary based on host device, file attributions, and other factors.

Just make sure to give it sufficient time to test sequential write speeds, since memory cards don’t do well with random write operations. If you are using a PC, CrystalDiskMark is a wonderful piece of software to test read / write speeds on any storage media. There are three main types of SD card: SD, SDHC (high capacity) or SDXC (extended capacity). SD cards typically offer 128MB to 2GB in storage capacity, too small for today’s modern cameras with higher resolutions. SDHC bumps this up from 4GB to 32GB, useful for most photographers and videographers. SDXC cards, meanwhile, range from 64GB to 2TB and are aimed at professional-level users who require more memory. Despite being one of the cheaper microSD cards in this guide, the Lexar Play surprised us during testing, popping out a healthy 75MB/s write speed and 83.1MB/s read speed. The latter didn't match up to its advertised 150MB/s read speeds, but it did excel at the stated 30MB/s write speeds, which means this card trumped some of the more expensive cards in our round-up. A Class 4 card is guaranteed to deliver at least 4MBps, while a Class 10 should surpass 10MBps. Similarly, many vendors report their speeds in terms of "x" rating, which is a multiple of 150KBps (the read speed of a standard CDROM drive). A 100x card can be expected to deliver more than 14MBps.
