Overview
Photographers and video editors with huge archives get two WD Red drives in one desktop enclosure, striped together for speed out of the box. It connects by USB-C with cables for both port types and adds two USB hub ports.
Striping the two disks raises speed and pools capacity, and a disk replacement tool is included. The default setup has no redundancy, so critical data needs a mirrored setup or another backup.
Who it's for
Content creators and families backing up several computers to one box. Laptop users on the move should choose a portable SSD.
Pros and cons
- Very large capacity
- Faster than single disk drives
- Two hub ports
- Both cable types included
- RAID-0 default has no redundancy
- Formatted NTFS, Mac needs reformat
- Heavy desktop unit
Performance notes
Speed comes from striping across two drives, which nearly doubles sequential reads compared to one disk. The same striping means a single drive failure takes the whole volume, so backups matter. USB-C provides the bandwidth to carry the combined speed.
