The 4TB and 5TB models measure in at 4.22 x 2.95 x 0.75 inches and 210g/7.4 ounces.Īlong with a redesign to slim down a bit, the My Passport is also available in three colors: black, red, and blue. Rather than your standard 7mm SSD or 9.5mm HDD, the HDD in this models measures 15mm thick, which also adds to the weight. Due to the increased number of platters that WD’s My Passport needs to reach 4TB and 5TB, the larger capacities are bit bulkier. The 1TB and 2TB models measure 4.22 x 2.95 x 0.44 inches and weigh 120 grams (4.2 ounces). WD’s My Passport comes in two sizes depending on the capacity you get. Of course, it is a SED or self-encrypting drive, as it comes with AES 256-bit hardware encryption. It comes with a 128MB DRAM cache and has the USB bridge and connector built-in rather than using a standard SATA connection. Encased within its plastic enclosure, WD opted to utilize a Shingled Magnetic Recording (SMR, a technology that overlaps data tracks to increase density)-based 2.5” HDD, model: WD50NDZW-11MR8S1 on our 5TB sample.
