X25-M 120 : 18.1s => 15.5s (-2.6s)
Vertex 3 240 : 17.1s => 14.4s (-2.7s)

In heavy multitasking perhaps we can have some (small) difference but it's hard to find a realistic case that i can use to benchmark.

For example during the bench i've tried to combine the launch of 3ds/photoshop/word/excel (wich in fact is already heavy) with a file copy (read+write) limited at 5 MB/s, i don't get any difference at all.

At the end, more than CPU limited, i think modern SSD are now "user" limited
Hi Marc, welcome to XS.

That does not surprise me. It's beyond my understanding to know how I/O processing works with either hardware of software; but both seem to like to wait for an I/O to finish before the next I/O is requested from the storage device. How quick that I/O is processed by the CPU/ RAM would therefore seem to have an impact.

Right now I'd say if you are using HDD an SSD would be the best upgrade, but if you already have an SSD a faster CPU would be the better upgrade choice. (Assuming you would have to choose one or the other )

Reliability is also a big issue for me and would be my number one choice, even over price.
