The SanDisk Extreme PRO 128GB microSDXC sits above the Extreme GO in SanDisk’s microSD hierarchy, delivering 250MB/s sequential read — 10MB/s faster than the Extreme GO 128GB — while matching the Extreme GO 128GB’s 120MB/s write speed at this capacity. The PRO designation brings three meaningful differences over the Extreme GO beyond the read speed increment: the Extreme PRO is backed by a lifetime warranty rather than the 2-year warranty on the Extreme GO, it carries the RescuePRO Deluxe data recovery software subscription (for recovering accidentally deleted files), and it is built to a higher endurance specification for sustained continuous-write workloads. For users who write to the card repeatedly over long periods — action camera users who record daily, content creators doing high-volume timelapse or drone footage — the Extreme PRO’s higher endurance rating provides longer reliable service life under sustained write stress than the Extreme GO at the same capacity.

The 250MB/s read speed is the practical ceiling of UHS-I bus technology (the UHS-I interface’s theoretical maximum is 104MB/s in SDR104 mode, but SanDisk’s rated speed reflects performance in the SanDisk-proprietary reader environment; real-world speeds on standard UHS-I readers will be lower but still exceed the Extreme GO). V30 video speed class (minimum 30MB/s sustained write) and U3 UHS class confirm 4K video readiness across action cameras, drones and high-end smartphones. A2 Application Performance Class (minimum 4,000/2,000 IOPS read/write) ensures app-on-card performance for Android devices without lag at random I/O operations. Temperature-proof, waterproof, shockproof and X-ray proof. SD adapter included for full-size SD slot compatibility. Lifetime warranty.
