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

When installing Windows 7 with BIOS set to AHCI, you don't have to install any chipset drivers, at least I didn't. You should have the Standard AHCI 1.0 Serial ATA Controller when using msahci driver, not that Intel Controller--which probably is the reason for your sub-par AS SSD benchmark result.

Didn't know that, thanks. Removed them now.

but like I said in the previous post, I did run the benchmark before I installed the chipset driver and the results were identical, the 4k read always around 14 MB/s.

Did you have both the msahci driver and the Standard AHCI 1.0 Serial ATA Controller?

In addition to the above, do you have Disk Defragmenter turned off or disabled for your SSD?

Yes, disk defragmenter turned off and the standard AHCI 1.0 Serial ATA controller
