If you save your files to the relatively slow HD, a faster SSD will change nothing except a slightly quicker start of your apps. 2 TB of SSD will currently cost you round 1000 $ I think, so if you want to change the drives it will empty your pocket. Apple introduced some hybrid drives which are big HD and little fast SSD in one housing. The SSD buffers the files quickly and sends them to the HD which feels fast, I guess.


I'm sure drives like that are also available for PC, they just have the risk, if one part fails, you might loose some buffered files. And one cannot make partitions on them.
