My new music player has a 1TB SSD. SSD makes sense for any system drive and given that it cost me just £150 extra to go from a small SSD system drive to a 1TB SSD which easily now contains the system and all my digital music - it was a no brainer. I've had enough HDDs fail on me to believe that reliability of the latest SSDs won't any worse and could be better. If I search for a track, the result is instant. My PC is fanless too so a spinning disk would be an anachronism.
However, you won't go far wrong with either option (HDD or SSD).
