At A Glance

Despite having two drive pressed together, Seagate's Backup Plus Fast drive gets all the power it needs from the host's USB port. And since the two drives are running in RAID 0, it delivers speeds faster than other portables with a single mechanical drive.

A plain and simple drive, with ample room for storage. The DashDrive HV620 from ADATA isn't flashy or faster than average, but it's got a lot of space and average speeds, with a great price-per-gigabyte.
