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. 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.

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.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). SanDisk’s Extreme Pro microSD cards are ideal for high-speed data transfer. SanDisk claims world-first sequential read speeds of 200MB/s and write speeds up to 140MB/s, with a Video Speed Class 30 rating. Read on for our real-world testing results of their latest microSD card. 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. L'app SanDisk Memory Zone è un'aggiunta utile per la gestione dei file, rendendo facile organizzare e trasferire dati direttamente dal dispositivo mobile. Ho apprezzato la sua interfaccia intuitiva e le opzioni di gestione file che offre. The SanDisk Extreme Pro microSD cards are intended for 4K video and other high-speed data scenarios, such as Android phones, action cameras, and drones. The smallest capacity card in the lineup is the microSDHC 32GB card rated for sequential performance of 100MB/s read and 90MB/s write. The 64GB-128GB microSDXC cards up the read to 200MB/s, and for maximum performance, the 256GB/400GB/512GB/1TB cards are 200MB/s read and 140MB/s write.

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 best microSD cards to buy in 2023 1. Integral Ultima Pro Premium High Speed: Best-value microSD card at higher capacities 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?

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. La robustezza di questa scheda è un altro punto a suo favore. Testata per funzionare in condizioni estreme, è impermeabile, resistente alle temperature, agli urti e ai raggi X. Questa caratteristica la rende adatta a situazioni di utilizzo varie, dalle avventure all'aperto alle condizioni più impegnative. 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. 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.
