Questions about this item

Will the USB 3.2 Gen 2 cable or Type-A adapter need replacing after heavy daily use?

The drive ships with a USB Type-C to Type-C cable and a Type-C to Type-A adapter; both are passive connectors with no moving parts and typically last the life of the drive.

What thermal limit throttles the NVMe controller during long 1050 MB/s reads?

Sustained maximum sequential read speeds of 1050 MB/s are limited by the drive’s internal thermal management, which reduces performance once the controller reaches its operating temperature ceiling.

How much power does the 52 g blue SSD draw when it runs all day over USB-C?

The portable SSD is bus-powered through the USB 3.2 Gen 2 interface, drawing all required power from the host port without an external adapter.
