Frequently asked questions
- Will an external SSD work with both a PC and a games console?
- Most do, but consoles often require a specific format and may only run games from internal storage. Check the console's storage requirements before buying.
- Do I need Thunderbolt or is USB enough?
- USB 3.2 suits everyday backups and photos. Thunderbolt or USB4 only benefits you for large video files or 4K editing, and your computer must support that port.
- How long does an external SSD last?
- For typical home use they comfortably last many years. Endurance is rated in terabytes written, which most users never approach, though backups are still wise.
