Certified and Tested
Each ThunderBay 4 solution undergoes OWC's multi-hour drive "burn-in" performance certification procedure prior to shipping. This ensures your ThunderBay 4 arrives operating properly, ready for demanding use.
4 drive bays plus so much more. Time-tested Cooling
Built on OWC's time-tested enclosure cooling technology, ThunderBay 4 utilizes an open "flow-thru" vented design with an oversized 92 mm, low-turbulence, noise-quieting fan to keep the drives running cool and reliably.
Multi-Drive
Daisy-chain up to six ThunderBay 4s for massive storage capabilities and increased performance, or connect multiple ThunderBay 4s to multiple Thunderbolt 3 ports to achieve exponential speed capabilities.
Vibration Dampened
ThunderBay 4's drive isolating design reduces sonic resonance, and is aided by over-sized, rugged, vibration-absorbing, non-skid feet.
DisplayPort 1.2 Support
Dual Thunderbolt 3 ports let you connect the display of your choice that your computer can support, including 4K displays.
SoftRAID XT works with macOS 10.12 or later and Windows 10. M1 Macs require macOS 11.3 or later. SoftRAID is licensed per computer.

Bought this raid device to replace my Drobo 5D3. Obviously quicker with the thunderbolt 3 ports. As quiet as the old one. Only time will tell if it’s as robust as the Drobo but I’m pleased. Setup with softraid XT is very easy as is prepping the new 6Tb hard drives
