    Just installed my kingston ssd and love it so far. Booting into w7 used to be 1 minute and 35 seconds. Now I boot into w7 around 38 seconds. My question is WEI is giving me a rating of 5.9 for "Disk data transfrer rate," does that sound right or is something wrong? I know my SSD isn't that fast but its giving me the same rating when I had my 5400rpm HDD installed.

    If you click "View and print detailed performance and system information", do you get a remark like the following?

    No in the note field mine said this "Caution: Based on the results of the WinSAT Disk assessment, your system drive may have slower response times under some workloads. Performance results will depend on the specific applications used and the amount of memory available. If your experience is satisfactory, no action is needed."

    Which drivers? Have you made sure that your SSD is aligned?

    Please install Intel RST latest version from Intel.com.

    If that didn't improve WEI then post a screen shot of AS-SSD without running the benchmark.

    For my own interest: will you post a CrystalDiskMark 3x100MB screenshot please?

    Hi Phil I installed the Intel RST latest version. But still get a 5.9 am I suppose to config anything in the RST program? Also what is AS-SSD, also I never used CrystalDiskMark, but I'll try.

    p.s I did go under the manage option in RST and it showing this information. So I know its on sata III.

    System disk: Yes
    Password protect: No
    Disk data cache: Enabled
    Native command queuing: Yes
    SATA transfer rate: 6 Gb/s
    Physical sector size: 512 Bytes
    Logical sector size: 512 Bytes

    OK. By the way, is this a clean install or a cloned one?

    The AS-SSD you said to not run, but post a screenshot is that what you needed? This was a clean install and I'm a ssd newb but the cdm screen those readings look really low.

    Well the AS-SSD shot tells Intel RST (iastor) is running correctly and alignment is ok.

    CDM tells performance looks bad.

    Here's a V100 that should be slower:

    Have you applied any tweaks or guides?

    I used this guide, but did not perform a couple of them is there anyones that I really should do?

    The SSD Optimization Guide - The SSD Review

    Also, how can I verify for sure I'm on ahci in the bios? Do you think my SSD is defective? The screenshot you posted is set at 5x100mb does it matter?

    OMG. These guides are completely unnecessary and it may be the reason performance is bad.

    Try restoring everything you changed on write caching.

    Okay. But is there a certain step on that guide that you see involving cach that I should have not done. Then I probably see if I change it or not. I do appreciate the help.

    These are the steps I used, the rest I left alone

    3 4 5 6 7 9 10 15 16 17 18

    I did not do step 8 "TURN OFF WINDOWS WRITE-CACHE BUFFER FLUSHING…OR NOT"

    Try toggling the write caching settings (8) to see if your 4K write performance improves.

    Check with CDM.

    Do a clean install, turn off Pagefile, do not apply those nasty tweaks and do the same test agian.

    After chipset driver, install the lastest version of RST.

    I usually go:

    Chipset - RST - grapich driver - sound driver - then ACER multimedia stuff.

    I agree with tuηays advice (except pagefile) but I suggest to not do a clean install yet.

    I think the low write performance is caused by write caching settings and it may be possible to resolve it w/o a clean install.
