Which Thunderbolt disk enclosure?

QI want to replace my external 8TB hard disk, which mostly stores my still images and videos, with an enclosure containing four SSDs. What’s the best solution using Thunderbolt 3?

AIf you can divide your files across four disks rather than using RAID to merge them into one, this can be affordable, although the choice of products is still limited. The OWC Thunderbay 4 delivers excellent Thunderbolt 3 performance with up to four 16TB SATA SSDs, but doesn’t offer hardware RAID, for which you’d need to use either SoftRAID or AppleRAID set up using Disk Utility. It’s well-engineered, has a quiet cooling fan, and has a second Thunderbolt port you can daisychain to another peripheral.

For hardware RAID support, you’d need a much more expensive system like a Promise Pegasus32 R4, and would need to populate it with all four SSDs to take advantage of its RAID features, whereas you can gradually fill a Thunderbay enclosure as you need. Going to faster NVMe SSDs would be seriously costly.

An external disk enclosure connected via Thunderbolt 3 can be filled gradually with SSDs if you don’t use it as a RAID array.
