Marketing Information

Designed as a workhorse external storage solution, the ThunderBay 4 4-Bay Thunderbolt 3 RAID Enclosure from OWC / Other World Computing can handle multi-stream compressed 4K video and other bandwidth-intensive operations. Built with four SATA drive bays that can handle 2.5" or 3.5" hard drives and SSDs, the ThunderBay 4 delivers sustained data transfer speeds of up to 1550 MB/s and connects to your host Windows or Mac system using a Thunderbolt 3 port, while a second Thunderbolt 3 port can be used to daisy-chain up to six ThunderBay 4 enclosures. There is also a dedicated DisplayPort 1.2 port that supports a 4K display. Thanks to the SoftRAID software RAID controller, the ThunderBay 4 can be configured as RAID 0, 1, 4, 5, and 10, each of which provides data redundancy, performance, or a combination of both. For those who do not require a RAID, JBOD is available.

SoftRAID XT works with macOS 10.12 or later and Windows 10 and 11. Intel-based Macs require macOS 10.12 or later. M1 Macs require macOS 11.1 or 11.3 and later. macOS 11.3 is currently available as a public beta. SoftRAID is licensed per computer. The SoftRAID serial number will work with both Mac and Windows but can only be active on one computer at a time. Additional seats can be purchased. RAID 4/5/1+0 (10) are currently Mac only at this time.

Please note that SoftRAID XT is included as a 30 day trial. After the trial ends, you must purchase the software to continue using it.
