OWC ThunderBay 4 4-Bay Thunderbolt 3 RAID 5 Enclosure

Thunderbolt 3
Thunderbolt 3 is a hardware interface that utilizes the reversible USB Type-C connector. 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
The ThunderBay 4 comes pre-configured in RAID 5, but also supports RAID 0, 1, 4, 10, and JBOD. Included SoftRAID license provides 3 years of coverage.
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
Daisy-chain up to six ThunderBay 4s for more storage capabilities and increased performance, or connect multiple ThunderBay 4s to multiple Thunderbolt 3 ports to achieve higher speed capabilities.
Vibration Dampened
The 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 ports let you connect the display of your choice that your computer can support, including 4K displays.
OWC Thunderbolt Cable
The ThunderBay 4 comes with a certified OWC Thunderbolt 3 cable.
