SanDisk Extreme microSDXC UHS-I 128GB 240MB/s

SanDisk Extreme microSDXC 128GB

The SanDisk Extreme 128GB microSDXC card delivers UHS-I performance with up to 240 MB/s read and 120 MB/s write speeds for action cameras, drones, smartphones, and handheld gaming devices. SanDisk positions the Extreme line above Ultra tiers for operators who move large files daily and need faster buffer clearing during 4K capture. The microSD form factor fits compact hosts while maintaining full-size compatibility through optional adapters in bundled kits.

Technical buyers evaluate this card for mobile content pipelines, edge recording nodes, and portable backup workflows. One hundred twenty-eight gigabytes supports extended 4K recording sessions on supported action cameras when bitrate settings allow. The U3 speed class confirms sustained write capability for video workloads. A1 Application Performance Class rating supports faster app launch and execution on Android devices that read the rating during adoption. Procurement should verify host maximum bus speed because UHS-I limits real-world throughput even when card ratings exceed interface ceilings.
