Western Digital My Book Thunderbolt Duo 4TB RAID External Hard Drive (Manufacturer Refurbished)
Designed for professional data or file storage, this RAID dual drive boasts 4TB of total storage space and two high-speed Thunderbolt ports so you can back-up and edit files seamlessly.
Safe, Redundant Storage
As a RAID (Redundant Array of Independent Discs) dual drive, the Thunderbolt Duo uses two separate drives to make two copies of all of your files. This way, you never need to worry about drive failure ruining your backups—you’ll always have the redundant drive to fall back on.
High-Speed File Transfers
Perfect for creative work, this drive’s 10Gb/s Thunderbolt port is so fast, you can edit photos and videos directly on the drive as though they were stored locally. Moreover, this drive is outfitted with two Thunderbolt ports, so you can daisy-chain up to seven drives (additional drives not included) together to create a massive amount of storage space.
With enough total space to store 1,000,000 MP3s or 1,000 hours of HD video, the Thunderbolt Duo has plenty of room for huge creative projects or whole-system backups.
