Overview
A compact drive in an aluminum and glass enclosure connects to a computer with the included cable and is recognized automatically. Files move by dragging them across, and no software is required to get started.
The reason to buy is easy portable backup with plug-and-play setup and recovery services listed in the title. The limit is the unclear sizing fields and a mixed warranty message between rescue services and limited warranty.
Who it's for
Windows and Mac users who want extra storage for documents, photos and backups will like the no-software start. Buyers needing very fast transfers or a rugged shock-resistant case should look at other models.
Pros and cons
- Plug and play, no software
- Works with PC and Mac
- Rescue Services in the title
- Compact portable body
- Dimension units disagree
- Mechanical drive speeds
- Warranty fields differ
- Platform field says PC only
Performance notes
Throughput is set by the USB link and the mechanical drive, so large copies run slower than on flash storage. The listing gives a read speed in the same range as the interface limit for such drives. Automatic recognition means no driver install.
