Intel X25-M 80gb low 4k read/write speeds

[idata]

I use to get 39mb/s write and 14.4 mb/s read using as ssd benchmark on the 4k test. Recently I am scoring 27.50mb/s write and 14mb/s read. What could cause this drop in performance. I am using ahci mode and msahci driver. Thanks

I am not familiar with Vista and SSD, so just taking shots in the dark here, First, do you have Disk Defragmenter disabled or turned off for the SSD? Are you doing RAID or have drive encryption? Have you looked at the Read Me for SSD Toolbox to see if there is some conflicting issue? http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18455 http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18455

thanks for the help, i did a raw install of windows 7 with AHCI and NATIVE turned on in the bios and ran it right away... all better:

I am glad to be of help. Congratulations!

Check the test results in about 10 days and see how it goes. If there is any issue with your results, post back here.

Can I jump in here? I have an Intel 80GB X-25M G2 in an old Dell XPS Gen2 with 3GHz P4 and 3GB RAM. The SATA is on a RAID controller that I have turned off in BIOS. There are no options in BIOS for AHCP. My transfer rates are really low. I did a clean install of Win7 on it, but defrag, indexing, fetching were not optimized for SSD, although "fsutil behavior query disabledeletenotify" says TRIM is enabled. I haven't been able to tell if alignment is set for SSD. Is my problem here that I am stuck behind an old SATA RAID controller? Can I do something to fix this? Thanks for any advice.

I just figured out how to add a picture to this message.
