Add RAID 5 storage to your Mac or Windows computer with the ThunderBay 4 4TB 4-Bay Thunderbolt 3 RAID 5 Array from OWC / Other World Computing. As you can guess from its name, the ThunderBay 4 features dual Thunderbolt 3 ports, which utilize the USB Type-C connector. There is also a DisplayPort 1.2 port for connecting up to a 4K display.
The ThunderBay 4 has four drive bays, which supports both 2.5" and 3.5" hard drives (2.5" HDDs do not need adapters). This particular ThunderBay 4 model comes with four 1TB 3.5" 7200 rpm drives for a total of 4TB storage capacity. The included drives are configured in RAID 5. With RAID 5, you get protection against a single drive failure. Three of the hard drives are used for storage while one hard drive is used for parity. If you want to reformat to RAID 0 or 1, 4, or 1+0, you can use the included SoftRAID software or the Windows Disk Management utility. This RAID array is compatible with macOS 10.12 or later and Windows 10 and later.
Please note that the included SoftRAID license provides 3 years of coverage.
