ThunderBay 4 8TB four-drive RAID

The OWC ThunderBay 4 is a desktop external enclosure that holds four 3.5-inch drives in a single black chassis. It connects through Thunderbolt and ships with a 0.7-metre cable. The unit arrives pre-configured with 8TB of total storage running at 7200 RPM and a 512MB cache. Hardware RAID supports modes 0, 1, 4, 5, 10 and JBOD.

Suits Mac and Windows RAID workflows

Editors and studios needing hardware RAID on macOS 10.12 through 13 or Windows 10 and 11 will find the ThunderBay 4 ready to deploy. The front-panel lock and included security keys add physical protection for shared environments. Buyers who need a single-drive backup device or portable bus-powered storage should consider other form factors. The four-bay design also exceeds the needs of users with modest capacity requirements.

Hardware RAID 0 1 4 5 10 JBOD

The built-in RAID controller is the specification that determines whether this enclosure matches a workflow. It presents the four installed drives as a single logical volume or mirrored pair without host software overhead. Supported levels include striping, mirroring and parity options up to RAID 10. If a project requires software-defined RAID or a different controller feature set, this hardware implementation will not align.

商品問答

Should I pick RAID 5 or JBOD for the 8.0 TB array?

RAID 5 gives you roughly 6 TB of protected space and survives one drive failure; JBOD presents all 8.0 TB as separate volumes with no redundancy.

What sustained throughput will I see from the 7200 RPM drives over Thunderbolt?

The four 7200 RPM drives can deliver multi-drive sequential speeds that saturate a typical Thunderbolt link, so real-world reads and writes run at the link's practical ceiling.

Does the Thunderbolt interface limit the 512 MB cache or 7200 RPM spindle speed?

No — the Thunderbolt connection has more bandwidth than the mechanical drives can fill, so neither the 512 MB cache nor the 7200 RPM speed is capped by the interface.
