OWC THUNDERBAY 4 32TB, FOUR-DRIVE HDD WITH DUAL THUNDERBOLT 2 20GB:
Add 32TB of Thunderbolt 2 storage to your Mac with the ThunderBay 4 32TB 4-Bay Thunderbolt 2 RAID Array (4 x 8TB, RAID 5 Edition) from OWC / Other World Computing. These drives are pre-configured for RAID 5 via software. 32TB provides you with plenty of space to store files such as music, photos, movies, and documents, but this array also allows you to operate a production workflow with 2K video, 4K video, and audio.
Within the array are four bays that each house a single 8TB hard drive. Each included 3.5" drive connects to the array via the SATA III 6 Gb/s interface and has a rotational speed of 7200 rpm. Since the array ships with four drives, they can be software configured as RAID 0, 1, 4, 5, and 1+0, each of which offers performance, data redundancy, or a combination of both. This array comes pre-formatted and is software configured as a RAID 5 volume.
This volume will be recognized on systems running with OS X 10.9.3 and later, and requires the included SoftRAID 5 via download for Mac OS X 10.8.5 or earlier. RAID 5 allows read speeds of up to 512 MB/s and write speeds of up to 446 MB/s.
The ThunderBay 4 comes with two Thunderbolt 2 ports which allow you to daisy-chain up to six devices such as additional ThunderBays, 4K displays, and more. Thunderbolt 2 offers a single 20 Gb/s bi-directional channel that allows you to stream and write 4K video at the same time. To help ensure a smooth operating environment, the array uses a 92mm noise-quieting fan.
Included with this ThunderBay 4 array is SoftRAID XT, a 3.3' Thunderbolt cable, a 3-prong power cable, and two keys for the front panel lock.
