The StoreJet 25M3 is a portable hard drive built to be more resistant to shock than most such products. It's aided by a tough rubberised jacket and internal damper frame. Available in three capacities – 500 GB, 1 TB and a generous 2 TB – we tested the latter largest model.
This drive has a dark-grey silicone jacket that Transcend calls Iron Gray, with a bright green end cap and green trim line.
An unusual addition to this drive is the One Touch Auto-Backup Button, a blue-ringed push button on the end cap that's designed to simplify the backing up of data to the drive.
