In this video, I unbox and install a Sabrent 2.5” to 3.5” SATA Bay Converter Mounting Kit. This allows you to install a 2.5″ SATA drive in place of a 3.5″ drive on computers that use a hard drive bay. The mounting kit was sturdily constructed. I did have a little trouble getting the screw lined up in the hard drive bay but I was able to get it to work.

This Corsair adapter didn’t line up with SATA port on the 3.5″ drive but it does hold two SSDs. This might work for some people: https://amzn.to/2gp2p86 (affiliate link)
