About: OWC ThunderBay 4 4-Drive HDD External Storage TB3 - 8TB

ThunderBay 4, OWC's flagship 4-bay RAID ready powerhouse is bigger and faster than ever before. Now with the unbelievable performance of Thunderbolt 3 – up to 1550MB/s sustained performance1– it’s the ultimate workhorse external storage solution. Not only faster, the new ThunderBay 4 Thunderbolt 3 is now natively compatible with both 2.5” and 3.5” drives, and with a redesigned chassis, it’s even cooler and quieter too. Add vast amounts of high-performance storage with ThunderBay 4. Utilize each of the four internal drives independently, or use the software RAID of your choice to set up a multi-drive array for high performance or data redundancy.

Edit, Experiment, Create, Design
Designed with performance in mind and engineered to harness the power of Thunderbolt 3, ThunderBay 4 is an incredibly flexible external storage solution with the throughput to support multi-stream compressed 4K video and other bandwidth-intensive operations. Highly configurable to perfectly match your performance needs. Use each drive independently, or in the RAID configuration of your choice for the optimal balance of performance and data-redundancy. Get the most out of your storage, take the brakes off your workflow, and do more with a ThunderBay 4.
