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

Excuse me for butting-in. I noticed that the last reply was still march 2010, but can I necro this post?

I recently noticed that my pc's booting time has doubled and checked my SSD's benchmark and found this

I used to use crystal disk mark to check but when I tried this one, I found out that it has an error.

I already tried all other advices above except where I have to format the disk and reinstall the whole thing so I can change

the driver (changing "iaStor" to "mahcpi".

Can anyone help me? Thanks in advance...

Your partition is incorrectly aligned. The alignment starts at the 104422 KByte boundary, which is not properly aligned for SSDs. This is indicated by the "104422 K - BAD" message in AS SSD. You need to re-partition the drive to have proper alignment. You can do this by properly aligning it and reinstalling the OS, or, you can purchase the Paragon's Alignment Tool and have it align the partition for you (without any data loss or need to reinstall).

I have the same issue on a brand new SSD, I just did fresh install of win 7 64 and my reads are in the 130's, my guess is where i went wrong was going to the acer web page and installing their 64 bit drivers for sata. so will my speed increase with just using the default windows drivers on a fresh install..My 80gb G1 at the office is out running it based on Crstal Mark. any help would be welcome, new to SSD and i dont want to go back....MY SSD ROCKS
