Featuring four drive bays equipped with hot-swappable 4TB 7200 rpm SATA III 3.5" hard drives, the 16TB array has a maximum data throughput of 2800 MB/s. Its hardware-based controller supports RAID 0, 1, 1E, 5, 6, and 10 configurations, and the fan-cooled drives are pre-configured for RAID 5. Connectivity to your host system is established using a 40 Gb/s Thunderbolt 3 port that also provides up to 85W of charging power, while a second Thunderbolt 3 port may be used for daisy chaining and supports up to 15W of charging power. If your system doesn't support Thunderbolt 3, both ports are backward compatible with 10 Gb/s USB 3.2 Gen 2. There is also a DisplayPort 1.4 connector that supports 8K displays for large and highly detailed projects. The drives come pre-formatted for macOS 10.14 or later, but may be reformatted for Windows 10.

As per usual, Promise Technology outdid themselves yet again. For a smaller option, the Pegasus32 R4 is the best option for data storage. Would recommend to buy at this price, especially from B&H who always ship well and fast - and have great customer service.
