The SanDisk Extreme PRO SDXC 128GB is the card working photographers default to: UHS-I pushed to its practical ceiling with up to 170MB/s reads, 90MB/s writes that keep deep RAW bursts flowing, and the U3/V30 rating that makes 4K capture routine. The most-recommended SD line of its generation, in the capacity that fits your shooting.
Burst-proof
90MB/s sustained-class writes
Shutter bursts live or die on write speed: 90MB/s clears the buffer fast enough that the camera, not the card, sets your pace through a wedding procession or a goal celebration.
Fast offload
Up to 170MB/s read
SanDisk’s proprietary UHS-I boost (with their SD readers) runs past the standard’s nominal cap — a full card offloads while the coffee is still warm.
Dependable
V30 — 4K without drama
The 30MB/s sustained write floor records 4K at consumer and prosumer bitrates cleanly — plus the shock, temperature and X-ray proofing SanDisk builds into the line.
Right choice if you…
✔ Shoot RAW bursts — sport, events, wildlife
✔ Record 4K on a DSLR or mirrorless body
✔ Want the industry-default pro UHS-I card
✔ Offload big shoots on deadline
Consider something else if…
✖ Your camera has UHS-II slots and you shoot pro video — the Extreme PRO UHS-II V90
✖ Casual photos — the Extreme (non-PRO) saves money
✖ You need microSD — different slot, see the microSD range

Frequently Asked Questions
Do I need a special reader for 170MB/s?
Full read speed needs SanDisk’s own UHS-I-boosting readers; in standard readers it tops around 95-104MB/s — still quick, and in-camera write speed is unaffected.
Is V30 enough for my 4K camera?
For the bitrates consumer and prosumer bodies use, yes. Only high-bitrate cinema formats demand V60/V90 — that’s UHS-II territory.
How many RAW photos per burst before slowdown?
Depends on the body’s buffer, but 90MB/s writes clear it among the fastest any UHS-I card can — this is the card bodies were benchmarked with.
Extreme PRO or plain Extreme?
PRO adds faster writes (90 vs ~70MB/s) and the boosted reads — worth it for burst shooters; the Extreme covers travel and family photography for less.
