I just bought an M1 Mac Mini and wanted to expand the storage space available so I bought this enclosure for an old 480GB SATA SSD I had laying around . Installation took less than 2 minutes, and macOS Big Sur recognized the drive immediately when I plugged it into my Mac Mini's USB-C port. Since then absolutely no problems. I feel a little warmth when I put my hand on the case, but I think it has more to do with the drive inside.
