About this deal

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. 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. With a massive 256GB of storage space, this microSDXC card is a dream come true for users who need ample room for photos, videos, apps, and more. It's perfect for smartphones, tablets, action cameras, and even Nintendo Switch users who crave additional space for their game libraries. You won't have to constantly worry about running out of storage with this card.

Sequential speeds matter most for copying large files and sustained data transfers, as they do when streaming 4K video to a phone or tablet, or recording 4K video from an action cam. Random read/write speeds are more important if you’re running apps or games from a microSD card installed in a smartphone or handheld gaming device. 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.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. 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. 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. 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?

Geschwindigkeit (★★★★★): Diese Karte hat eine A2-Bewertung, was bedeutet, dass sie auch mit Apps und Anwendungen gut umgehen kann. Das ist besonders wichtig, wenn Sie große Apps oder Spiele auf Ihrem Smartphone verwenden möchten. 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). 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. Compatible device required. Full HD (1920x1080) and 4K UHD (3840 x 2160) support may vary based upon host device, file attributes, and other factors. See www.sandisk.com/HD When these things are on sale, they are a good bargain. My camera will do 4k type of video shooting at 30 frames per second. That will easily eat up a small sd card at 128gb or below in a short period of time.For 64GB-1TB ONLY: 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. 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? Up to 130MB/s write speeds for fast shooting (Based on internal testing; performance may be lower depending upon host device interface, usage conditions and other factors. 1MB=1,000,000 bytes.)
