What to know before buying

Listing details to confirm

Speed and interface details are inconsistent: the title states up to 150MB/s read and USB 3.2, the item type states up to 130MB/s and USB 3.1, manufacturer details list USB 3.0 and the A+ text specifies USB 3.2 Gen 1 with up to 130MB/s for 16GB–64GB. The manufacturer says host device and usage conditions can affect performance and a USB 3.0 port is required. The specification also lists USB Type-A and USB Type-C connectivity, but the product title identifies a Type-A drive, so confirm the connector on the selected listing. Password protection requires a software download and is listed for Windows 10+ and macOS v10.9+. RescuePRO Deluxe requires registration and download, with terms and conditions applying. Actual user storage is less than the stated capacity.

Customer feedback praises the compact size and storage for music, with some saying it can stay attached to a laptop. Reports on reliability and speed are mixed, including reports of failure after several months and low transfer rates, and some customers say the drive gets very hot.
