SSDs are not a magic bullet, it's unlikely they will give you a killer |
18 |
performance improvement that makes you go "WOW!!!" |

SSDs suck at random writes. |
21 |
Typical usage scenario on a workstation is lots of random writes compared to |
22 |
relatively few random reads - reads tend not to be all that random as you |
23 |
re-read the same thing often and it gets cached. |
24 |
|
25 |
Intel SSDs are far superior at random writes than any other SSD out there but |
26 |
it's still nowhere near as optimised as spinning drives, and kernels by and |
27 |
large are still optimised for spinning drives too. |

This may account for your overall feeling of under-whelmedness why still |
30 |
seeing a significant boot-time speed up. You also have enough RAM so that |
31 |
almost an entire typical workstation session could fit in RAM and seldom touch |
32 |
the disk especially with a large interval between disk syncs |
