Another great product by OWC!
I had a spare SSD I wanted to incorporate into my Mac Pro 2,1. Local suppliers had "mounting brackets" to install a 3.5" drive into a 5-1/4" full height drive bay, however, these were clearly designed for generic PC case installations, not the drive trays used in the Mac Pro models. I tried one anyway, but as expected, it didn't work. In order to do so, I would not only have to use the bracket, I would also have to obtain SATA data and power cables to connect the drive - something that is not easily accessible in the Mac Pro drive bays.
So online I went to OWC and ordered the Adaptadrive Drive Converter Bracket....
No, it was not $4.00 like the cheaply made drive mounting bracket I had attempted to use - but when I got it and opened the package I knew why - and why I buy from OWC.
Inside was a highly engineered, powder coated aluminum bracket that was designed to allow a 3.5" drive to fit into the drive sleds of my Mac Pro perfectly, while also allowing the installed drive to match up to the connectors in the Mac Pro drive bays. All hardware was included along with detailed instructions, not that I needed them.
In a matter of a few minutes I had my spare SSD mounted in an unused drive sled and installed in my Mac Pro. The fit and finish was perfect, as expected.
OWC really excels at designing and manufacturing items like this. I don't know why I even bothered trying to find a generic off the shelf solution when I should have just ordered a Adaptadrive up front and saved myself the hassle....
