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. 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.

Dispositivo compatível requerido. A compatibilidade com vídeo em Full HD (1920 x 1080) e 4K UHD (3840 x 2160) pode variar dependendo do dispositivo utilizado, das características do arquivo e de outros fatores. Consulte: www.sandisk.com/HD 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). Next and last is the synthetic IOMeter benchmark where I also included numbers for the Samsung PRO Plus. IOMeter 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. 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.

Running out of space for your apps, games, videos or photos? Find the speed and capacity you need with our pick of the best microSD cards

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 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. Se requiere un dispositivo compatible. La compatibilidad con Full HD (1920x1080) o 4K UHD (3840x2160) puede variar según el dispositivo host, los atributos del archivo y otros factores. Consulta www.sandisk.com/HDCapture fast-action photos or shoot 4K UHD video 2 with write speeds of up to 140MB/s. 8 The SanDisk Extreme PRO microSDXC UHS-I Card lets you shoot more and faster. 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. 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.
