Besides, the company has a platform that can house four of such platters, thus enabling 4 TB 2.5”/12.5 mm HDDs. 2.5” SMR platters of such capacities are not something brand new in general because Seagate has been using them for several months but it would be noteworthy if Western Digital has started to use them for commercial products. We believe these should be based on either PMR or SMR technology. However, what the company did confirm is that the new My Passport 4 TB HDDs are based on 2.5”/12.5 mm hard drives featuring four 1 TB platters. Western Digital traditionally does not disclose a lot of technical specifications of its external HDDs, such as spindle speeds or cache sizes. While the update looks fairly regular, it is important what is inside these new 4 TB drives. As for visual aesthetics, the design of the new 4 TB My Passport drives remained the same as that of the latest generation. The drives also have hardware AES-256 encryption. 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. Western Digital last week introduced several new members to its My Passport family of external hard drives.
