Overview
Crucial built the X8 as a pocket external SSD that plugs into a laptop, console, phone or tablet over USB-C, with an adapter for older USB-A ports. Flash storage means no spinning parts inside, so it copes well with being carried between machines.
Large capacity in a palm sized shell lets a whole photo archive or game library travel in a bag. Top speed needs the USB-C cable on a matching port, and the included adapter drops the link speed on older computers.
Who it's for
Photographers, video editors and gamers who shuttle big folders between a PC, a Mac and a console get space and speed in one small box. Field workers who need stated ruggedness ratings should look at a drive that lists them.
Pros and cons
- Large capacity in a small shell
- USB-C cable and USB-A adapter included
- Works with PC and Mac
- Listed for Xbox One and PS4
- Write speed not listed
- Adapter halves the link speed
- Plastic enclosure per the listing
Performance notes
Transfer speed is set by the slowest link in the chain: the port, the cable and the host computer's own storage. The USB-C to USB-C cable reaches the drive's full interface speed, while the USB-A adapter caps it lower. Long sustained writes depend on the internal flash and cache behavior, which the listing does not detail.
