Overview
A 4TB portable hard drive sized for carrying a full backup or media library. Bundled backup software adds ransomware defense, and the drive can be locked with a password plus hardware encryption, backed by a 3-year warranty.
This is a spinning-platter drive, not an SSD, so it trades top-end speed for a much lower cost per terabyte, which is the usual reason to pick it over a flash drive at this capacity. The same My Passport line runs up to 6TB, so 4TB sits in the middle of the range rather than at the top.
- 4TB portable capacity
- USB 3.1/USB 3.0 compatible
- Backup software with ransomware defense
- Password protection plus hardware encryption
Who it's for
Fits anyone who needs cheap bulk backup capacity for photos, video or documents and can live with mechanical-drive speeds. Less suited to people who want SSD-level transfer speed or plan to carry the drive daily in a bag.
Strengths and trade-offs
Drawn from this product's published specifications.
- Slim body despite the mechanical drive inside
- Large capacity at a low cost per terabyte
- Password lock backed by hardware encryption
- 3-year limited warranty included
- Mechanical drive, so slower and more shock sensitive than SSD
- Password protection requires installing the bundled software first
Performance notes
Being a mechanical drive, throughput is capped well below what an SSD delivers, though USB 3.1/3.0 keeps the interface from being the bottleneck. The included management software runs scheduled backups and watches for ransomware-style behavior, and the password lock pairs with hardware-level encryption rather than a software-only lock.
