Western Digital My Book Thunderbolt Duo External Dual Hard Drives (Manufacturer Refurbished)
These hard drives are ideal for Macs, because they transfer data back and forth via dual Thunderbolt ports, whether that data is full-length movies, work projects, or the thousands of memes that you will one day make viral.
Do More with High-Speed Thunderbolt
Whether you’re uploading 4K video or backing up your entire photo library, Thunderbolt connectivity helps you move files to and from your computer smoothly. When connected, the Thunderbolt ports support data transfer speeds of up to 10GB/s—double the speed of USB 3.0—in both directions.
Because there are dual drives built in, you can place all your files on one half, then back them up to the other half. You can also use each half individually or combine them into one megadrive for the fastest data retrieval.
The hard drive can help you daisy-chain up to seven devices such as monitors and media players to create a smooth-operating custom system for creating projects while using minimal cables.
