SanDisk 128GB Extreme PRO microSDXC card + SD adapter + RescuePro Deluxe, up to 200 MB/s, with A2 App Performance, for smartphones, action cameras or drones UHS-I Class 10 U3 V30

Product Information

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

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. 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). 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. 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.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 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.

Next and last is the synthetic IOMeter benchmark where I also included numbers for the Samsung PRO Plus. IOMeter Esto corresponde solo a la tarjeta. Consulta www.sandisk.com/proof para conocer las limitaciones y obtener información adicional.

SOLO para 64 GB a 1 TB: El rendimiento A2 es de 4000 IOPS de lectura y 2000 IOPS de escritura. Para 32 GB: El rendimiento A1 es de 1500 IOPS de lectura y 500 IOPS de escritura. Los resultados pueden variar según el dispositivo host, el tipo de aplicación y otros factores. 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.

The best microSD cards to buy in 2023 1. Integral Ultima Pro Premium High Speed: Best-value microSD card at higher capacities 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? La velocidad UHS de clase 3 (U3) designa una opción de rendimiento diseñada para admitir la grabación de videos en tiempo real con dispositivos host habilitados para UHS. La clase de velocidad de video 30 (V30), la tasa de captura de video sostenida de 30 MB/s, designa una opción del rendimiento diseñada para admitir la grabación de video en tiempo real con dispositivos host habilitados para UHS. Consulta www.sdcard.org/consumers/speed.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.
