Because it's SSD the speed of backing up a lot of files is not a problem. A great solution for backing up files in a small physical space.
I would recommend this product to a friend!

Works like a charm with an old iMac. Using it as a boot disk.

I was having problems with my iMac(Late 2012) and when help community recommended that I use an External SSD as my Startup Disk to replace the older, slower Fusion Drive running macOs Catalina. After searching, and checking reviews of suggested drives i bought the OWC Envoy PRO USB 3.0 960GB SSD External. The drive arrived in less than two weeks. It was a couple of weeks before i was able to feel secure enough when my computer started up and seem safe enough to proceed. After connecting, then following the formatting instructions and then moving all of my system to and setting the SSD as the StartUp Drive, everything has been faster in starting up and running and has been so the past few weeks. Highly recommend this drive to update an older computer and very easy to set up.
