What is an NVMe enclosure, and is it a good fast drive?
Short answer: It's a case that turns an M.2 NVMe SSD into a USB-C, USB4 or Thunderbolt external drive — a fast, roomy option that suits Storage Studio well. Format it as APFS and check it with Run benchmark.
An NVMe enclosure is a small case that turns an internal-style M.2 NVMe SSD into an external drive over USB-C, USB4 or Thunderbolt. It's a popular way to get a fast, roomy external drive, and it's exactly the kind of drive Storage Studio is designed around — apps and folders you move run straight from it.
The enclosure's connection decides the top speed, so match it to what your Mac supports. Once assembled, erase it as APFS in Disk Utility and check it with Run benchmark in Choose Drive. Some enclosures get warm under long copies; that's normal, but give it some airflow.
