Four-bay Thunderbolt 2 RAID array

The OWC ThunderBay 4 RAID 5 Edition is an external desktop enclosure that ships with four 3.5-inch hard drives installed for a total of 8.0 TB of usable capacity. Dual Thunderbolt 2 ports provide the host connection and allow daisy-chaining of additional Thunderbolt devices. The unit supports hardware RAID 5 and JBOD modes, and a built-in cooling fan helps maintain drive temperatures during sustained workloads.

Mac users needing redundant external storage

This system suits creative professionals and small studios who want a single-volume, fault-tolerant archive that connects directly to a Mac via Thunderbolt 2. It is not suited for users who require more than four drive bays, internal installation, or a host interface other than Thunderbolt 2.

Dual Thunderbolt 2 host interface

The enclosure connects to the host exclusively through two Thunderbolt 2 ports, which also serve as the daisy-chain pathway for other Thunderbolt peripherals. If your computer lacks Thunderbolt 2, this product cannot be used without an appropriate adapter or dock.

Questions about this item

What bandwidth does the Thunderbolt 2 host interface provide for the RAID 5 volume?

The Thunderbolt 2 host interface connects the four installed drives to the computer and serves as the throughput ceiling for the RAID 5 volume.

What drive size and bay count must a rack or shelf accommodate for this 8.0 TB unit?

The enclosure holds four 3.5 inch drives in four bays and measures 7 inches high, 5.3 inches wide and 9.7 inches deep.

How is the RAID 5 array initialised on this OWC ThunderBay 4, and which step is commonly missed?

Connect the dual Thunderbolt 2 ports, power on the unit, then use the supplied software to create the RAID 5 set; the step often missed is completing the software initialisation before writing data.
