Extreme PRO Dual 256GB USB 3.2 Gen 2

The SanDisk Extreme PRO Dual is a 256GB USB flash drive with both USB Type-A and USB Type-C connectors. It is built for professionals who need fast, portable storage across laptops, tablets and Android phones without carrying separate adapters.

Up to 1000MB/s read and 900MB/s write

Sequential reads reach 1000MB/s and writes reach 900MB/s over USB 3.2 Gen 2, so large creative projects and critical documents transfer quickly. The 256GB capacity handles current workloads, while the series scales to 2TB for users who need more headroom.

Questions about this item

Will the 256GB Extreme PRO Dual drive run at full speed on my older USB 3.0 Type-A port?

It connects to USB 3.0 Type-A ports and operates at the host port's maximum speed, which is lower than the drive's 1,000MB/s read and 900MB/s write capability.

How can I verify the drive delivers its rated 1,000MB/s read and 900MB/s write speeds after setup?

Run a benchmark tool such as CrystalDiskMark on a USB 3.2 Gen 2 port; sequential results should approach 1,000MB/s read and 900MB/s write.

What is included in the box and do I need any extra cables or adapters?

The drive itself is the only item supplied; its integrated USB Type-A and USB Type-C connectors plug directly into both port types without extra cables.
