slow ssd performance in 2710p

[Pablo Vidal]

I've just installed a Sandisk SSD UATA 5000 64gb in my hp 2710p.

I'm getting good values at reading multiple small files: about 11/3.5mbps (read/write) and writing large files (50mbps)...

but I'm getting (nonsense) only 20mbps at reading large files.

I'm tried with clean installations of Windows 7 64 bits, and Windows XP, and I get same results in both cases.

Does anyone have idea why read speed seems to be limited to 20mpps?
