The Mercury Pro 32TB Thunderbolt 8-Drive SSD 2-Bay Thunderbolt 3 RAID Array from OWC features two bays that each sport a 4TB SSD to deliver a total raw capacity of 32TB for your Thunderbolt 3 system. The eight NVMe M.2 SSDs in each U.2 bay are preconfigured in a hardware RAID 0 array that strips the data across all the drives to provide speeds of up to 2800 MB/s. You can reconfigure the drives into RAID 1, JBOD, RAID 4, RAID 5, and RAID 0+1 depending on your storage needs with the included SoftRAID XT software.
