SanDisk Extreme Pro 1 TB microSDXC Memory Card + SD Adapter with A2 App Performance + Rescue Pro Deluxe 170 MB/s Class 10, UHS-I, U3, V30

Product Information

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. 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 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

SanDisk Extreme® PRO microSDXC™ UHS-I CARD, Best Micro SD

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. 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. 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. Get faster app performance for an outstanding smartphone experience thanks to the SanDisk Extreme PRO microSD card’s A2 5 Specification.

Thank you!

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. 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? 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. For 256GB-1TB: Up to 200MB/s read speeds, engineered with proprietary technology to reach speeds beyond UHS-I 104MB/s, require compatible devices capable of reaching such speeds. Up to 140MB/s write speeds. For 64GB-128GB: Up to 200MB/s read speeds, engineered with proprietary technology to reach speeds beyond UHS-I 104MB/s, require compatible devices capable of reaching such speeds. Up to 90MB/s write speeds. For 32GB: Up to 100MB/s read speeds; up to 90MB/s write speeds. Based on internal testing; performance may be lower depending upon host device interface, usage conditions and other factors. 1MB=1,000,000 bytes.

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. What’s more, this card comes into its own on random read/write speed tests. Here, we saw the fastest performance we’ve seen from a microSD card, reaching speeds of over 12MB/sec. Other cards from Lexar, Kingston and Samsung are catching up, but this is still the speed king for app and game performance. Given that it’s only slightly more expensive than the basic Ultima Pro, that makes it one of the top options for smartphone or Switch use.On top of this, most cards now have a “V” (for video) rating, going from V6 all the way to V90, indicating write speeds of 6MB/sec to 90MB/sec. You need a V30 card to shoot 4K video at speeds of 60 to 120 frames per second, while V60 is the base level for shooting 8K video at 60fps. V90 is theoretically capable of handling 8K video at up to 120fps. However, given that only a handful of professional-grade cameras can offer that, and that they tend to use the larger CFexpress 2.0 cards for storage, this isn’t what you might call a must-have.
