all the ssd devices that are in mac's and pc's are of the cheap kind. sure they are faster than mechanical disks, but again, they are very cheap. for a mac mini, i would use a hdd which i do. i am involved in this technology for a living and the normal price for a enterprise class ssd can be around $12,000 depending on configuration. these ssd devices vary quite a bit compared to the cheap ssd devices found in macs and pc's: they provide more fault tolerance by over-provisioning so they have a larger mttf compared to a hard drive.
also, music won't sound better by using an ssd vs. a cheap hdd. for playing music off a mac or pc, you don't need the speed that ssd provides. way over-kill. the benefit you will get is a more quiet pc and a more cooler running pc.
