I have a Mac Pro 2 X 3 Ghz Quad-Core Intel Xeon with 10 gig of memory. I have a 1 tb main drive and 2 other 1tb drives. If i replace my main drive to an SSD drive will I see any advantages in speed? I keep my computer pretty clean and it seems like my Mac has slowed down a bit or hangs. I think it has to do with all the programs I have. I am not quite ready to drop the money on a new mac pro because I don't see a huge advantage yet since what I have is still pretty powerful. Any feedback on this? What kind of SSD drive would I need to get and what sizes are out there? Thanks all in advance!
