WD My Passport SSD 256GB Review

Rating: 8.0.

WD has a number of drive ranges sitting under the My Passport banner including the WiFi equipped My Passport Wireless Pro, all based around standard hard drives. However the latest addition to the range, the diminutive My Passport SSD offers a different level of performance altogether to the rest of the family.

At launch, the My Passport SSD range consists of three capacities, 256GB, 512GB and the flagship 1TB model. WD supplied us with the entry level 256GB drive for reviewing purposes. Going by the size of the My Passport SSD, the drive inside it is a M.2 format SSD. The drive it uses a USB 3.1 Type-C interface.

There are no details in the specification information on WD's website as to the NAND type and the make / model of the controller. Using the CrystalDiskInfo utility, the drive inside the case is recognised as a SanDisk SD8TN8U256G2000. This corresponds to SanDisk's X400 drive which means it uses 15nm TLC NAND and has a Marvell 88SS1074 4-channel controller.

WD quote transfer speeds for the drive of up to 515MB/s and back the drive with a 3-year warranty.
