OK, so I understand that you get faster read and write times with an SSD and faster start up times too but I'm confused as to what "should" go on there and as a result the size of the drive that I'd need. OS is a given, along with programmes and applications but is there any advantage to having music or photos on there? If not then a 60g or 128g would be more than enough as music and photos seem to take up most of my space. I guess video should be stored on the SSD, which are large files, but only for editing I'm guessing? Currently running a 2011 2.5 Mac Mini with 8 gig Crucial RAM and just using it for the normal surfing, photo and video editing and the like. Don't turn it off so fast reboot is not the draw for me that it is for others. Your thoughts would be appreciated.
