Product details
Same 4TB My Passport muscle as the black model, in the blue finish for setups that are tired of everything being black. Under the color it is the full package: Acronis True Image backup software with ransomware defense, password protection with 256-bit AES hardware encryption, and USB 3.2 Gen 1 transfers over a single bus-powered cable. The slim enclosure travels well, the software keeps backups automatic, and WD's 3-year limited warranty keeps it worry-free. Pick your capacity, pick your color, stop thinking about storage.
This is the 4TB My Passport in blue — same drive, same full kit as the black model, in the finish for setups that are tired of every accessory being black. Four terabytes holds a complete, versioned backup of a gaming PC, a rotating library of installs parked off the SSD, and the household photo and video archive, in a palm-sized enclosure that travels in a pocket or a laptop bag without a power adapter.
The color is not just cosmetic in a house with more than one drive: blue is the one you can call out by name — the backup drive, not the scratch drive — and spot instantly in a drawer. Under the finish it is the standard My Passport routine: Micro-B connection over USB 3.2 Gen 1 at up to 5Gb/s, bus power only, and Acronis True Image for Western Digital software scheduling backups with protection designed to help defend against ransomware.
Password protection with 256-bit AES hardware encryption guards the contents if the drive ever leaves in the wrong bag, and WD backs this 4TB blue model with a 3-year limited warranty. Pick your capacity, pick your color, and stop thinking about storage.
