Like the other Western Digital’s My Passport HDDs, the new models feature a USB 3.0 interface and come with automatic WD Backup software. The new drives are based on the WD’s new 2.5”/12.5 mm HDD platform which uses high-capacity platters. The new portable external HDDs can store up to 4 TB of data, an improvement over previous-gen portable storage solutions from the company.
