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

Well, even 14.4 MB/s is on the low side. Try running the optimizer from SSD Toolbox and see what happens. As a point of reference, I am including a test of mine that is also from an 80GB Intel G2 SSD. Do you also have a G2 SSD?

I ran the optimizer and results are still the same. Also it is a gen2 drive

Are you saying there was a time in the beginning when you had results similar to mine above, or were your test results always significantly worse than mine regarding 4K with AS SSD benchmark tool?

Do you have the SSD connected to first SATA port? Do you have any other hard drives that are not SSD connected?

In addition to the above, are there any issues in Device Manager? Are you using the latest firmware update? Can you post a screenshot from AS SSD showing test results?
