You have a misaligned partition, if you run XP align your partition with some utility (like MagicParted). If you run Win7 / Vista SP1+ then reinstall cleanly and do not use cloning programs which may give you a misaligned partition.

These are 4K sector drives; thats likely causing your issue.

It could be something else, but the most common cause for poor performance on 4K sector "advanced format" harddrives is that your partition is not 'aligned'. Installing Windows 7 fresh should give you aligned partition; do a quick format on your harddrive to be sure so do not reuse the existing partition.

AS SSD can detect whether your partition is properly aligned; says OK or BAD depending on whether its aligned or not.

Good luck. :)

ok heres the report:

-fresh install of windows7 x64 did not help.
-programs installed is the latest drivers only (sound and gpu).
-problems i had still facing me after the format.
-the buffer size did not change, still 32.

so....RMA?

AMD Phenom x4 955 BE
4 GB DDR2 @800MHZ Ramz
Gigabyte GA-MA78G-DS3H revv1.0
WDC WD10EARS 1TB
Gigabyte 720w PSU

Download CrystalDiskInfo and CrystalDiskMark, and post both the SMART information and benchmark here for analysis.

It would be really great is you could also post a screenshot of AS SSD, this checks other things as well.

Do you have anti-virus or other protection technology installed? This can also reduce your I/O performance.

I do have the same drive and I'm having no props at all, hdtune says buffer size unknown but still I'm having no problems whatsoever , the drive is running as is should.

Try to run the SMART tests....
