Solid, Reliable, and Cool

The ThunderBay IV has a durable aluminum enclosure that protects the four internal drives while keeping them cool thanks to its superior heat dissipation. A locking faceplate keeps the drives secure. Power and drive status light show system status at a glance.

Real-Time Editing

You can now work at the full speed of the drive. Create, backup your data, or edit multiple uncompressed video streams faster and more efficiently than ever. See some impressive benchmarks »

The Perfect Mac Pro Migration Drive

You don't have to give up your drive bays when migrating from a Mac Pro tower to the new Mac Pro. Simply plug in the ThunderBay IV to your new Mac Pro and you'll have four drives with a Thunderbolt interface capable of running all the drives at full speed – just as if they were installed internally.

Thunderbolt Daisy-chain Capable

Add high–performance features by daisy chaining up to six devices plus one high-resolution display. Of course, the biggest benefit is even when you use a ThunderBay IV, you will still have an available Thunderbolt port.
