What is limiting my SSD speed?

Hi,
Op's system isn't that old to think it was IDE mode

Please check mentioned setting in bios or at least run AS SSD benchmark (it displays used driver, and it's enough to tell IDE/AHCI modes apart) and show results.
Don't just leave us with unsolved mystery

Sorry, I completely missed your comment. I checked the BIOS setting and it was indeed in IDE mode. I changed it to AHCI and now numbers are where I think they should be (except for 840's seq write speed which is supposed to be around 410 but is 494 for some reason).
Thank you very much!
