X25-M 80GB low 4k read

[idata]

Hi all,

I've been testing my new system that has an Intel X25-M 80 gb and I seem to be getting a lower 4k read value than most benchmarks I see, usally around 19/20 MB/s while mine is 14MB/s.

This is on a fresh windows 7 x64 instalation, asus p7p55d motherboard and a I5-750 cpu. Sata option in BIOS with AHCI when installing windows.

- system restore off

- index off

- hibernation off

I've read all the related threads here and more and still no solution.. any ideas?

thanks in advance

I have the exact same drive and my results are very similar to yours. My 4K read is 15.17

This is on a Windows 7 Pro 64 bit clean install. System restore, hibernation all off. Although I still have the previous firmware 02HA.

Don't know if this is relevant but I seem to have duplicate entries in my device manager.. Didn't noticed this before this last windows instalation but speeds were the same as they are now.

I get the same scores as you. Have you tried using the default msahci driver instead of the intel? The msahci driver supports automatic trim in win 7.

I am using the default windows msahci driver as you can see in the benchmark screenshot.

I think the additional controller appeared when I installed the chipset driver of my motherboard. I did run the benchmark tool before the instalation of the chipset and the results are almost identical.
