Overview
Backing up a whole library of photos, video and documents is the job of this large portable drive, which connects over a USB-A cable. Hardware encryption protects the data, and the included software handles backup and passwords.
A large library fits on one drive and can be locked with a password, which suits laptop owners with growing collections. The limitation is that it is a spinning disk, so speed trails flash and rough handling is a risk.
Who it's for
A desk or bag where a large backup lives between uses is the right place. Those who work from the drive all day with large files might prefer a flash drive.
Pros and cons
- Xbox One compatibility listed
- Backup software included
- Spinning disk, slower than flash
- Software needs a download
- Body is fairly thick
- Rough handling risk
Performance notes
Data passes through a moving head, so large sequential copies run well while many small files are slower. Hardware encryption scrambles data on the drive itself. The USB link and the drive's media speed set the top transfer rate.
