Product Information

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. Get faster app performance for an outstanding smartphone experience thanks to the SanDisk Extreme® microSD card’s A2 7Specification. When I try to copy files to the microcard it will transfer a few gyges but no more. I can see the folders have copied but they are empty. I can copy a few files at a time but this is will too time consuming. These standards cover the speed of the interface between the microSD card and your device (or memory card reader), as this can also limit the maximum speed of data transfers between the two. UHS-I has a maximum speed of 104MB/sec, and you’ll usually see a Roman numeral “I” beneath the U1 logo. UHS-II takes that up to 156MB/sec (with data transferring in both directions) or 312MB/sec (with data transferring in only one direction).

The Integral Ultima Pro might be cheap, but it’s still capable of respectable speeds. We logged its sequential read speeds at 96.1MB/sec and its sequential write speeds at 87.4MB/sec, although it came in slightly slower on our random read/write tests. We test microSD cards in a high-speed USB microSD card reader, connected to a laptop via a USB 3.2 Gen 2 Type-A connection. We use a combination of the CrystalDiskMark and AS-SSD benchmarks to test both sequential read and write speeds and random read/write speeds. 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 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.Capture fast-action photos or shoot 4K UHD video 2 with write speeds of up to 130MB/s. 9The SanDisk Extreme® microSDXC™ UHS-I Card lets you shoot more and faster. 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. While the SanDisk Extreme microSDXC card is not the cheapest option on the market, it provides exceptional value for its price, considering the vast storage capacity, speed, and reliability it offers. It's an investment that ensures your data is secure and your devices perform at their best.

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? Adapter inklusive (★★★★★): Der im Lieferumfang enthaltene Adapter ermöglicht es Ihnen, die microSD-Karte in verschiedenen Geräten zu verwenden, dar 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. Zuverlässigkeit (★★★★★): SanDisk hat einen hervorragenden Ruf für Zuverlässigkeit. Diese Karte ist wasser- und stoßfest, so dass Ihre Daten gut geschützt sind. Like the Micron C200, the only other 1TB microSD card currently on the market, the Sandisk Extreme is likely to use the company’s 96-layer 3D QLC (quad-level cell) NAND technology. It does support capabilities such as command queuing and caching but remains constrained by the UHS bus, which will pave the way to microSD Express in a not too distant future.

Often, fast sequential speeds come at the expense of random read/write speeds, but the A2-class 1066x is an exception; it’s not as speedy as the Integral Ultima Pro Professional High-Speed card below, but it’s faster than the SanDisk Extreme Pro and Samsung Evo Plus on this count, making it a fine all-round performer. If you’re looking for a card that can run apps or cover video on your mid-range or high-end smartphone, you won’t get much better than this. The best microSD cards to buy in 2023 1.

Kapazität (★★★★★): Mit 256 GB bietet diese Speicherkarte jede Menge Platz für Fotos, Videos, Apps und andere Daten. Das ist ideal für Smartphones, Actionkameras und Drohnen, die große Mengen an Daten produzieren. 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.Die SanDisk Extreme microSDXC UHS-I Speicherkarte ist eine ausgezeichnete Wahl für alle, die große Datenmengen auf ihren Geräten speichern möchten. Mit einer Kapazität von 256 GB und der bewährten Qualität von SanDisk bietet diese Speicherkarte großartige Leistung und Flexibilität.

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?

With the right card reader, the Professional High-Speed version of the Ultima Pro can be a serious speed demon. With Integral’s own high-speed card reader, we were disappointed with its 99MB/sec and 88MB/sec sequential read/write speeds, but in a third-party high-speed reader, we saw read performance leap to 173MB/sec, with sequential write speeds of 139MB/sec. That write speed is the fastest we’ve seen from a UHS-I card. The SanDisk Extreme microSDXC card boasts impressive read speeds of up to 190MB/s, ensuring that your data transfers, app installations, and content loading are blazing fast. This is especially important for users who shoot 4K videos or engage in demanding tasks where speed is crucial. The same holds for laptop users (Windows, Chromebooks or MacBooks) that want an easy and cheap way to increase the internal, local storage capacity without resorting to swapping the solid state drive (and resorting to the dreaded process of disk cloning). Adding 1TB to a laptop with 128GB storage can now be done in seconds!
