SSD crippled performance please help

I'm running a dell studioxps with a Samsung PM800 256GB SSD and it seems to be not running optimally. For one the new 7 performance rating gives it a 5.9 the same score as my friends 7200 rpm HDD. I've benchmarked it at 125 - 150 mb/s read and 25 mb/s write. This seems terribly slow and I am wondering if anyone can help me figure out why.

Thanks

    When you formatted the drive to install Windows 7, did you perform a full or quick format? How full is the drive? What is the partition structure on that disk?

    Did you read what I posted in the other thread? http://icrontic.com/forum/showpost.php?p=720201&postcount=33

    You are running a laptop, which means they most likely have crippled the southbridge to run at SATA1 not SATA2 speeds.

    As I posted.. 125 - 150 in ATTO on that drive = SATA1 on the controller. See my benchmark on my Dell (from early 2008) below.

    Post a screenshot of the CPU-z mainboard tab like in the upper left of this photo.

    Looks like you have several things going on in the background that were slowing the speeds.

    agg now I feel dumb. I was running on battery power before which is why the low numbers once I connected everything shot up

    haha ya still I'd like an explanation of 7's performance index cuz I think those speeds deserver higher than a 5.9 :/

    Do you still get 5.9 with it plugged in?

    Reality check

    5.9/7.0 from a laptop really isn't anything to ashamed of!
