4-bay Professional-Grade Enclosure

Dual Thunderbolt 2 | RAID 5 | 4 Drive Bays | Mac

Add the capabilities of Thunderbolt 2 speed and storage to your Mac with the ThunderBay 4 Hard Drive Enclosure (RAID 5 Edition)from OWC / Other World Computing. This is a four bay, SATA III (6 Gb/s) enclosure and each bay will support a 3.5" hard drive or a 2.5" hard drive or SSD. Each 2.5" drive requires an optional NewerTech AdaptaDrive adapter. Once drives are installed, you can RAID them via the included SoftRAID 5 software. While this array will provide you with plenty of space to store files such as music, photos, movies, and documents, it also allows you to operate a production workflow with 2K video, 4K video, and audio.

The drives can be software configured with different RAID options that offer multi-drive performance or data redundancy. When configured as a RAID 5, the enclosure features read and write speeds up to 675 MB/s and when configured as a RAID 0, read and write speeds reach up to 1342 MB/s.

The ThunderBay 4 comes with two Thunderbolt 2 ports that provide data transfer rates of 20 Gb/s. Dual Thunderbolt 2 ports allow you to daisy-chain up to six devices such as additional ThunderBays, 4K displays, and more. To help ensure a smooth operating environment, the array uses a 92mm nosie-quieting fan.

Included with this ThunderBay 4 array is SoftRAID 5, a 1 meter Thunderbolt cable, an 3-prong power cable, 2 keys for the front panel lock, and a Mac compatible software bundle.

Please bear in mind that while users are free to select drives of their choice for this RAID, variable spin drives, such as WD Red and WD Green, are not recommended. The issue with variable spin drives is that because the drives could potentially be spinning at different speeds, this could lead to constant rebuilds within the RAID, as it could think that one or more drives are not in operation. While WD Red and WD Green drives are specifically being mentioned, please bear in mind that variable speed drives also manufactured by other companies, such as Seagate, are also not recommended.

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 ports also support DisplayPort 1.2 that allows daisy-chaining displays through the drive



SoftRAID 5
SoftRAID combines advanced RAID modes, fast performance, monitoring, e-mail notification, and fast rebuild capabilities that only software RAID can deliver. ThunderBay 4 models with drives come pre-configured in RAID 5, and are plug and play ready with OS X 10.9 or later. Advanced features such as drive notification and monitoring require SoftRAID installation
