Thunderbolt 3

Doubling the speed of its predecessor, Thunderbolt 3 features a maximum throughput of 40 Gb/s when used with compatible devices. The connector also transmits data via USB 3.1 at up to 10 Gb/s, and dual-bandwidth DisplayPort 1.2 allows you to connect up to two 4K displays simultaneously. Additionally, you can daisy chain up to six devices from a single Thunderbolt 3 port.
RAID & JBOD Support

Time-Tested Cooling
Built on OWC's time-tested enclosure cooling technology, the Thunderbay 4 utilizes an open "flow-thru" vented design with an over-sized 92mm, low turbulence, noise-quieting fan to keep the drives running cool and reliably.
Multi-Drive

Can I have 4x 20tb hard drives as Raid 5 and have a Mac and PC (Windows 11) connected and using the drive at the same time?
Asked by: Travis
The OWC ThunderBay 4 4-Bay Thunderbolt 3 RAID 5 Enclosure should be able to support 4x20TB drives in RAID 5, however, it can only be connected to one computer at a time. In order to have the ability to connect to both the Mac and PC simultaneously, you will need a NAS.

You can have two different RAID families in this box, however moving drives from another box with a RAID family already configured may not be compatible.
