Extreme PRO USB-C 256GB

The SanDisk Extreme PRO USB-C flash drive delivers up to 1000MB/s read and 900MB/s write speeds over a USB 3.2 Gen 2 Type-C connector. It provides 256GB of portable storage for creatives and professionals who move large project files between laptops, tablets and desktop workstations. The lightweight black casing makes it easy to carry in a pocket or bag.

Universal Type-C integration

A single USB Type-C plug connects directly to modern hosts without adapters, freeing up legacy USB-A ports for other peripherals. The drive draws power from the host port so no external supply is needed, keeping cable count low in mobile setups. Compatibility spans Windows, macOS and Android devices that support the USB 3.2 Gen 2 interface.

256GB capacity headroom

The 256GB volume comfortably holds hours of 4K footage, raw photo libraries or virtual-machine images while leaving room for incremental backups via the SanDisk Memory Zone app. RescuePRO Deluxe software adds a recovery safety net for accidental deletions. Users needing multi-terabyte archives or sustained write workloads beyond 900MB/s will require higher-capacity or desktop-class storage.

Questions about this item

Does the USB 3.2 Gen 2 interface maintain 1000MB/s reads during long transfers?

The drive is rated for up to 1000MB/s read and 900MB/s write over USB 3.2 Gen 2; sustained rates depend on host controller and file mix.

How warm does the SDCZ890-256G-G46 get and is there a fan?

The metal casing acts as a passive heatsink; it warms under continuous load but has no fan and no published thermal-throttle threshold.

What host port is required to use the USB-C connector on this 256GB model?

A USB-C port supporting USB 3.2 Gen 2 (10Gbps) is needed to reach the advertised 1000MB/s read and 900MB/s write speeds.
