TeamGroup's X1 Max is the ultimate stick SSD. It looks just like a regular flash drive, but it houses an internal SSD, and you get USB-A and USB-C connectors along with 1000MB/s transfers.

The D1 SSD Plus is a striking-looking, all-aluminum enclosure featuring the 40GBps USB4 protocol, with a single M.2 NVMe slot inside with thermal compound strips included.
