Backup critical data with the 2TB ThunderBay 4 mini 4-Drive SSD Thunderbolt 3 RAID 5 Array from OWC / Other World Computing. Featuring four 2.5" drive bays, this RAID array offers a total of 2TB of storage divided between four SSDs. Equipped with two Thunderbolt 3 ports, the ThunderBay 4 mini supports transfer speeds up to 1556 MB/s when using RAID 0, allowing for quicker backups or daisy-chaining multiple arrays for extended storage.

This array comes pre-formatted in RAID 5, but supports RAID 0, 1, 10, and 4 modes. The included software controller, SoftRAID XT, offers driver certification checks, email notifications, volume validation, and drive failure prediction. The software controller also allows for easy volume management, so you can choose what to use RAID volumes for and how much space is allocated for backup. The ThunderBay 4 mini is compatible with Windows 10 and later, as well as MAC OS X 10.13 and later. Furthermore, independent volumes can be booted with macOS. An ASMedia ASM-1062 chipset functions as the SATA Controller while an Intel JHL6540 controls Thunderbolt 3 operating modes.

Housed in black aluminum, the array features a locking front panel offering access to the individual bays. The back panel includes a Kensington Security Slot. The ThunderBay 4 mini comes with a 100-240V power supply, and outputs 12V and 6A, or 72W.

Air cooled, this array uses a single 60mm fan and is designed to operate in temperatures between 41 and 95 degrees F. Measuring 7.5 x 4.6 x 3.8", the small form factor of the ThunderBay 4 mini is designed to fit desktops, racks, and DIT carts, with a total weight of 2.51 lb.
