Since this is not a raid enclosure, does that mean all 4 drives format into one large drive? or as 4 single drives?
The TerraMaster D4-320 4-Bay USB 3.2 Gen 2 Enclosure, B&H # TED4320, would recognize the drives as 4 single drives; however, you could use tools built into your operating system to create what is referred to as a spanned drive, where it would combine all 4 into a single volume without using RAID. In macOS, it is called a Concatenated (JBOD) set, and you can use Disk Utility to create a set; on Windows, it is known as a Spanned volume, and you can use disk management to create it.
