Add RAID 0 storage to your Mac or Windows computer with the ThunderBay 4 Four-Bay Thunderbolt 3 RAID 0 Enclosure from OWC / Other World Computing. As you can guess from its name, the ThunderBay 4 features dual Thunderbolt 3 ports, which utilize the USB Type-C connector. There is also a DisplayPort 1.2 port for connecting up to a 4K display. The ThunderBay 4 has four drive bays, which supports both 2.5" and 3.5" hard drives (2.5" HDDs do not need adapters). With the included SoftRAID Lite software you can format the ThunderBay 4 to RAID 1. RAID 4, 5, and 1+0 are also supported with a RAID software of your choice.

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 and JBOD Support
The ThunderBay 4 comes pre-configured in RAID 0, but also supports RAID 1, 4, 5, and 1+0.
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.
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 adn 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 6.6' (2 m) certified OWC Thunderbolt 3 cable.

Most unopened items sold by Melrose Inc. in new condition and returned within 30 days will receive a refund or exchange. The return window for items sold online begins once the order has been invoiced. Invoicing happens when any part of the order is shipped, delivered by a courier service or made ready for pick up.

Software is not returnable and not refundable. All sales are final. This is generally part of all webcarts selling software. It is buyer beware. The reason for this is once an end-user customer sees a License Code then that code is 'spoiled' because they can use it to gain access to the software.  Once a License Code is registered by a customer that product is available to that customer and therefore the code cannot be returned.
