Product details

The workhorse portable: 4TB of black, slim, palm-sized storage that backs up a gaming PC and still fits in a jacket pocket. My Passport pairs its capacity with Acronis True Image backup software that includes ransomware defense, plus password protection backed by 256-bit AES hardware encryption. It connects over USB 3.2 Gen 1 through a Micro-B port with the cable in the box, runs entirely off bus power, and carries WD's 3-year limited warranty. The default recommendation when someone asks for a backup drive, full stop.

Four terabytes in black is the classic My Passport formula at the capacity most gaming households actually need. It holds a full backup of the main rig with version history to spare, a deep bench of game installs parked off the internal SSD, and the family photo and video archive — and it still slides into a jacket pocket. Keep it plugged in at the desk for scheduled backups, then toss it in a bag when the library needs to travel.

The routine is deliberately simple: one Micro-B cable carries both data and power, transfers run over USB 3.2 Gen 1 at up to 5Gb/s, and the included Acronis True Image for Western Digital software handles scheduling and helps defend your files against ransomware. There is no subscription and no cloud account standing between you and your own copy of your data.

Because a drive this useful will hold things that matter, WD builds in password protection backed by 256-bit AES hardware encryption — lose the drive and the files stay locked. Finished in black, sized at 107.2 by 75 by 19.2 millimeters and covered by a 3-year limited warranty, this 4TB My Passport is the default answer when someone asks which backup drive to buy.
