    Intel X25-M G2 160GB, slightly slow performance?

    Just installed an Intel X25-M G2 into my XPS 17 Sandy Bridge and it's not as fast as other G2's I've seen benchmarks of. Enabled write caching, AHCI in BIOS.

    I did a format before Windows 7 SP1 install, however it didn't create the 100MB partition as the drive was secondary. Will it still sector align during install without that partition?

    Any other tips to increase speed?

    Screenshots of AS SSD and CDM

    Thanks

    Temporarily disable intelppm in your registry and repeat CDM 3.0 at 3x 100MB.

    AS-SSD and CDM at 5x 1000MB create a large amount of writes which does not help longevity.

    Ok thanks for the feedback Phil, I'll try it later tonight as I'm at work.

    This is what I'm comparing it against:

    Here's my Intel X25-M 160GB in a Phenom II x4 840

    We have different 4K QD32 numbers and slightly different 512K numbers. It could be due to the overprovisioning I've done on mine (120GB vs. your 149GB). I'd say it looks pretty much in spec, though.

    Isn't the XPS 17 a laptop?

    If so you can't compare benchmarks with desktops or you will be forever disappointed.

    Too much emphasis on saving power in a laptop.

    Frankly the numbers look pretty good coming from a G2 device in a laptop.

    Are you using MSAHCI? or AMD Sata drivers?
    Because I am using AMD AHCI driver and I have slightly better numbers.
    Mine overprovisioned to 129Gb/160Gb

    That has no bearing on the performance. It's limited by the chipset and SATA speed (and CPU if it's a really slow one), neither of which should inhibit performance on a fairly new laptop.

    There are several hundred (if not several thousand) posts on this and other fora that dispute your thought.

    Apparently power management is a major impediment to SSD performance in a laptop.

    Are the people who say so basing that on synthetic performance or real world performance?

    I think they're basing it on synthetic performance.

    Using the power management feature in Windows, sure. If you choose "balanced" or "high performance" it can make a difference, but at high performance there is little to no effect compared with a desktop counterpart. That is probably what they are discussing. Not that laptops are inherently gimping SSD performance.

    I'm of this opinion. Whilst I appreciate laptops do have a lot of power saving built in, when set to max performance + running off mains electricity, I'd expect to see the same performance as a desktop if all parts are the same.

    Just curious to see how others gained more performance with older systems. My XPS 17 has 2.2ghz quad core, 555M graphics, 8gbit RAM so hardly underspecced!

    Added a word. I think that is what you mean ;)

    Touche! Did a bit of testing and got AS score of 414 using MS AHCI driver. Will probably stick with Intel drivers for power saving anyway....
