# What is an NVMe enclosure, and is it a good fast drive?

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.
