Windows Drive speed test HDD / SSD

Built into cmd for Windows is a neat utility for testing the raw speed of your HDD’s / SSD’s. Here we’ve tested two drives of different type namely Western Digital Green 2Tb HDD, Intel 128Gb X-25M SSD.

To run this utility on Windows, do the following:

  1. Open an elevated command prompt

    Click Start Orb then type cmd in the search box
    Right click on cmd and select Run as administrator, you may not have to do this and just run as normal, depending on your version and setup of Windows.
    Tip: Open quickly: Windows Key + R, cmd enter

  2. In the Command prompt window, type winsat disk -drive

    To test E: just type winsat disk -drive e
    To test C: just type winsat drive (you do not need to type C here)

  3. Post the results here >>

WD 2Tb Green

wd 2tb
Drive not being written to other than test

Intel 128Gb SSD

intel x25m
Worth noting the SSD was in C: drive operation so being written to whilst test was carried out. Performance probably slightly down because of it.

Even with the SSD being the drive in operation it is significantly quicker than the HDD.

I think the 3rd (last) column in the output may refer to the Windows Experience Index, seems to tally up.

OCZ 128Gb Vertex 4 SSD

Vertex 4 SSD
This is running FW1.5 and in AHCI mode but still not achieving full performance.

    Nice; will have to see what that old 2009 128Gb SSD does on 6GB/s port.

    Have a new PCIe SSD drive making into the 2012 rig… think it’s gunna need Win8 for testing :)

    @anno, grab an SSD mate, the difference is night and day.

    I would recommend a 128GB Vertex 4 SSD; keep your HDD for media.

    yes TY !
    I was building a pc and saved a bit on this drive
    59 eur
    What a Pile of Sh%t this seagate is ..sorry but it really is ..Its in effect slower then the old series of barracuda !! WTF ?
    All runs at windows benchmark 7.9 but my hdd this is rubbish
    I ll have to get a smallish ssd for OS
    maybe one of these cache ssd?
    they move stuff i use automatically /
    then i wont have to reinstall ..

    Probably about right; check out the 2TB WD Green from the article, it’s running cr@ppy random read times too.

    Having said that, they are still good for backup and media streaming at 1080p.

    My first SSD was an Intel 80GB SATA 3Gb/s, and even that crushed any HDD I’d ever used. I used it for the OS and some programs.

    Even the cheap SSD’s will outshine HDD.
    Check out this old YT video I did of the 80GB Intel SSD:
    http://www.youtube.com/watch?v=MRjlNSUyhuw

    That’s pretty much Word, Excel, Outlook, Fireworks, Firefox, IE, Photoshop opening pretty darn quickly :)
    Not particularly scientific, but shows some real world speed to these SSD’s.
    Go grab one!
