Overview
A spinning disk inside a desktop enclosure stores the data and connects by USB, with a separate power adapter. Drag and drop copies files, the drive is detected on Windows and Mac without software, and Time Machine use needs a reformat.
The reason to buy is a large backup volume with almost no setup and a cable and adapter in the box. The limit is mechanical speed and a desk-bound design that needs its own power. The listing gives the warranty as one year plus a recovery year in the title and two years in the specs.
Who it's for
Desk backups for a family, a photographer or a small office are the setting. Travelers, and anyone who wants quick random access for editing, should use a smaller portable drive or an SSD.
Pros and cons
- Very large capacity
- Drag and drop setup
- Cable and power adapter included
- Data recovery service listed
- Needs wall power
- Mechanical speed only
- Warranty terms conflict in the listing
Performance notes
Read speed follows the platter spinning inside, so large sequential files move well but many small files are slower than on an SSD. The USB link rate is a ceiling the disk does not reach. Mac Time Machine use requires reformatting the drive first.
