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.
