The ThunderBay IV is a four drive RAID with a Thunderbolt connector. Other World Computing says the drive can be configured for RAID 0, 1, or 5. Personally RAID 5 would be the most attractive for this configuration since it offers large and fast storage with a redundant drive in case of failure. That means the RAID can continue functioning if a drive goes down and then can rebuild itself once replaced. If speed is your thing, a RAID 0 can provide up to 880 MB/sec or so read and write performance, according to OWC.
The system offers dual Thunderbolt ports so you can add on additional devices to your Thunderbolt chain. You can connect up to 5 devices, and if you were to buy five ThunderBay IV, you could have up to 96 TB of storage. It also offers active fan cooling, which in my experience seems to result in better drive life.
OWC is selling the ThunderBay IV in a variety of kits. A bare enclosure starts out at $495 and equipped with 16 TB of HDD storage will run you $1400. You can also do SSD for up to 4 TB for $3700.
