The RAID 5 Advantage
RAID 5 merges the four drives inside ThunderBay together for exponential performance gains over a single drive, the combined capacity of three of the drives, and data redundancy that allows the array to still work even if one drive were to fail!
Certified and Tested
Each ThunderBay 4 solution undergoes OWC's multi-hour drive "burn-in" performance certification procedure prior to shipping. This ensures your ThunderBay 4 arrives operating properly, ready for demanding use.
4 drive bays plus so much more. Time-tested Cooling
Built on OWC's time-tested enclosure cooling technology, ThunderBay 4 utilizes an open "flow-thru" vented design with an oversized 92 mm, low-turbulence, noise-quieting fan to keep the drives running cool and reliably.
Multi-Drive
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 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 2 ports let you connect the display of your choice that your computer can support, including 4K displays.
Backed by OWC
Should you ever have a question or troubleshooting need, you can rely on OWC's award-winning support.

Reviewer: Anonymous Age: 35-44 Experience Level: Power User Owned Product: less than a month
Rating: 5/5 Solid build, easy setup August 8, 2014 We purchased the 16 TB ThunderBay 4 to replace a several-years-old Qx2 model whose power supply started to go bad after a power surge hit our house. The ThunderBay unit itself is very solid and it was a snap to get the drives in and everything set up. The noise level from the fans is minimal and we definitely appreciate the data redundancy that the RAID 5 array gives us; the SoftRaid software was useful and easy to install as well. In terms of speed we are seeing anywhere from 150MB/s to about 190MB/s in everyday use - but as we currently only have Thunderbolt "1" machines we're not realizing the full potential of the array. The fact that the ThunderBay should perform even better as we upgrade computers in the future was a selling point for us as we expect to use the unit for many years.

I'd definitely recommend the Thunderbay 4 to others (and already have!)

I would recommend this item to a friend! This review is from 16TB OWC ThunderBay 4, four-drive HDD with dual Thunderbolt 2 ports, RAID 5 Solution.
