SanDisk Extreme PRO 32GB UHS-II SDHC Memory Card

UHS-II Interface

300/260 MB/s — Why Two Rows of Pins Matter

Standard SD and UHS-I cards use a single row of electrical contacts on the back of the card. UHS-II adds a second row of pins, creating a faster data pathway that raises the interface ceiling from 104MB/s to 312MB/s. The SanDisk Extreme PRO uses this to deliver 300MB/s read — meaning a full 32GB card offloads to a UHS-II compatible reader in approximately 2 minutes rather than over 5. At the camera end, 260MB/s write handles the highest-bitrate recording modes that professional mirrorless cameras offer. The second row of pins is backwards compatible — this card works in UHS-I slots and cameras but operates at UHS-I speeds (up to 104MB/s) when the host does not support UHS-II.

V90 — The Professional Standard

90MB/s Minimum Write — No Stalls Under Load

Video Speed Class ratings define the minimum guaranteed sustained write speed — not average, not peak. V30 guarantees 30MB/s minimum. V60 guarantees 60MB/s. V90 guarantees 90MB/s sustained at all times, regardless of how much data is already on the card or how long the camera has been recording. 8K RAW video at 12-bit requires approximately 2,000Mbps — around 250MB/s write. 4K RAW on high-end mirrorless cameras regularly exceeds 400Mbps. V90 is the only Video Speed Class that reliably handles these workloads without dropped frames or recording interruptions. For photographers, V90 means even the most aggressive RAW burst sequences — 20fps+ on a full-frame sensor — will not exhaust the card’s buffer clearance rate.

Professional Build

Write-Protect Switch · RescuePRO · Lifetime Warranty

The mechanical write-protect switch on the side of the card locks it against accidental formatting or deletion — critical when the card holds an entire day’s RAW files during a shoot. Shock, temperature, waterproof and X-ray resistant construction provides field durability. RescuePRO Deluxe data recovery software (included as a download code) can restore accidentally deleted photos and videos — a practical safety net for a card used in professional or semi-professional contexts. The lifetime SanDisk warranty covers manufacturing defects for the life of the product. Pair with a UHS-II compatible reader such as the SanDisk Professional PRO-READER SD and microSD for maximum 300MB/s offload speeds.

Great choice if you…

✔ Own a UHS-II compatible mirrorless camera or DSLR
✔ Shoot continuous 4K RAW or high-bitrate video
✔ Need V90 minimum sustained write for demanding burst sequences
✔ Want the fastest possible card-to-computer offload speed
✔ Use Canon EOS R, Nikon Z, Sony Alpha, Fujifilm X-T or Panasonic S series

Consider something else if…

✖ Your camera only supports UHS-I — a UHS-I Extreme PRO will deliver the same in-camera speed at a lower price
✖ You need more than 32GB — UHS-II versions are available in 64GB and 128GB
✖ You need a microSD card — this is a full-size SDHC card only
