Questions about this product?
  • 4 x 4TB 3.5" 7200 rpm Enterprise HDD
  • 4 x 3.5" SATA III 6 Gb/s Drive Bays
  • 2 x Thunderbolt 2 Interfaces
  • Supports RAID 0, 1, 4, 5, 1+0, & JBOD

The OWC ThunderBay 4 16TB 4-Bay Thunderbolt 2 RAID Array (4 x 4TB, RAID 5 Enterprise Edition) is pre-configured with four 4TB Toshiba MG03ACA Enterprise-grade drives set up in RAID 5 via SoftRAID XT software. This array features two Thunderbolt 2 ports with transfer speeds of up to 20 Gb/s, making it suitable for a wide variety of workflows such as video and photo editing, audio production, and much more.

Actual read and write performance in RAID 5 are around 544 MB/s and 551 MB/s respectively. If needed, Thunderbolt 2 connectivity also supports daisy-chaining with up to six devices as well as DisplayPort-equipped displays. Using the SoftRAID XT software, you can reconfigure these drives from RAID 5 to alternate configurations including RAID 0, 1, 4, 1+0, and JBOD.


ThunderBay utilizes an open "flow-thru" vented design with a 92mm, low-turbulence, noise-quieting fan to keep the drives running cool and reliably.


Daisy-chain up to six ThunderBays for massive storage capabilities and increased performance, or connect multiple ThunderBays to multiple Thunderbolt 2 ports to achieve exponential speed capabilities.

Vibration Dampened

ThunderBay's drive isolating design reduces sonic resonance and is aided by over-sized, rugged, vibration-absorbing, non-skid feet.

DisplayPort 1.2 Support

The Thunderbolt 2 ports also support DisplayPort 1.2 that allows daisy-chaining displays through the drive.
