Yes, *if* you have the money to invest in SSD's (Solid State Drives) then they are the way to go. Here down under we are looking at $200 for a 30GB SSD, so two (2) for a RAID-0 config would be a nice $400, well you would not get much change.
For me, 60GB is way too small, considering this system has two (2) 250GB in RAID-0 giving me 465GB usable space, I have used near half now, so for me to swap over to SSD's I would not get much change from $1900.
