SSDs are not a magic bullet, it's unlikely they will give you a killer performance improvement that makes you go "WOW!!!" SSDs suck at random writes. Typical usage scenario on a workstation is lots of random writes compared to relatively few random reads - reads tend not to be all that random as you re-read the same thing often and it gets cached. Intel SSDs are far superior at random writes than any other SSD out there but it's still nowhere near as optimised as spinning drives, and kernels by and large are still optimised for spinning drives too. This may account for your overall feeling of under-whelmedness why still seeing a significant boot-time speed up. You also have enough RAM so that almost an entire typical workstation session could fit in RAM and seldom touch the disk especially with a large interval between disk syncs -- alan dot mckinnon at gmail dot com
