Last week I successfully swapped the lower hard drive in my 2011 mini server for a MX100 SSD. A great result. I would like to refresh the several year old hard drive in the upper slot now. I use this drive for my iTunes library and some other media. Stock drive is 500 GB 7200 RPM. Is 7200 needed/helpful for this use? If so, I was considering this WD Black 7200 RPM 750 GB: http://www.amazon.com/Western-Digital-Black-Notebook-WD7500BPKX/dp/B00DSUTX3O I would like a drive that doesn't necessarily make too much noise. I don't mind some whirl, but I don't really want a tick. If that one is not appropriate, what would you recommend? Thank you.
