    Hi i just installed a Corsair Neutron GTX 240gb SSD, and I am getting normal Read speeds of 500+MB/s but my write speeds are less than 200 MB/s. Does anybody know why?
    I have disabled defrag, pagefile, and all that stuff to optimize ssd's. Can anybody help?

    I am running
    Bio A09
    RAID mode

    Try switching to AHCI mode in BIOS, and run this test again, maybe it will help.

    might also want to enable Write Back Cache in the intel RST utility. I dont know how it would effect large file transfer speeds, but it does make a major difference in small file size writes.

    glad to hear that it worked for you. i was interested in getting the Neutron GTX 480GB to replace my optical drive for mass-storage. it seems like until now 480GB ssd's had crap IOPS/Write speeds, at least corsair/sandforce ones. glad to see we finally have ssd's available that dont take a massive performance hit over 240GB. it may all amount to nothing in my case as it would be replacing the optical drive and as such would be limited to sata2, but at least I wont be paying a sick amount of money for a drive that performs @ 1/2 the IOPS of the 240GB.

    my other thought as far as thats concerned was to get a 240GB Force GS for the optical and run it in a 3 drive RAID 0 with the 240GB Force GT and 240GB Atlas mSATA. I'm not sure what kind of benefit it would have with one drive being limited to sata 2. the Force GT uses synchronous chips and the Atlas uses toggle chips so if i go this route ill probably move the Force GT to the optical and put the GS (also toggle) in the main hdd bay. with my current raid setup I break 1000 in ATTO @ 64k file size. even if it only adds 285ish (sata2's max) to my read/writes id be happy. i would imagine IOPS would go up significantly as well.

    im going to test a similar setup this weekend using 3 120GB sandforce drives to verify it can run a 3 drive RAID 0, but it looks possible as i see all 3 in the bios level raid management.
