Western Digital My Passport WDBRMD0040BGY-WESN 4TB portable hard drive

Portable 4 TB USB 3.2 Gen 1 storage

The Western Digital My Passport WDBRMD0040BGY-WESN is a 4 TB portable hard drive in Silicon Grey that connects over USB 3.2 Gen 1 using a USB-C cable. It is formatted for immediate use with Windows PCs, Macs, Chromebooks, gaming consoles, phones and tablets. Hardware-based 256-bit AES encryption and password protection are built in, and device management software is included for automated backups.

Suits users who want simple high-capacity portable

This drive suits anyone needing up to 4 TB of space for photos, videos, games or documents across multiple devices without reformatting. Buyers who require solid-state transfer speeds, ruggedised drop protection or a hardware RAID configuration will not find those features here. The mechanical design also makes it less suited to environments with constant vibration or extreme temperature swings.

USB 3.2 Gen 1 interface determines transfer ceiling

The single specification that decides fit is the USB 3.2 Gen 1 interface, which sets the maximum data-rate ceiling for every host device. If your workflow depends on sustained throughput above that interface limit, a different interface technology is required. For workloads that stay within the USB 3.2 Gen 1 envelope, the 4 TB capacity and cross-platform readiness make this a practical choice.
