  • Please help with RAID 0

    I have installed Windows 7 x64 on Raid 0 (128KB Stripe Size) (two Phoenix Pro FM-25S2S-80GBP2). My motherboard is Asus P5Q-E with a Q6600 and 4GB DDR2 800.
    I'm new to raid and SSD. Coming from HDs I thought SSD would be as fast as lightning but it just feels slow. So I have done some benchmarks with the following results:







    Is there a problem with the speed? How do I know if I have to update firmware for SSD?
    What is that Intel Storage Technology buzz about?

    I've done some video converting and the speed seems to be the same as a single HD!!!?!
    Also when I click Computer, System Properties and then Device manager it sometimes takes a second or two to open.
    Opening Crysis 2 takes the same amount of time as a single HD.

    Please tell me if this is normal or I am doing something wrong. Thank you.

    Video rendering is CPU bound majority of the time. Unless you're encoding to a RAW format (which then becomes HDD bound because the CPU does no work compressing it, but the files are huge so the HDD's need to keep up).

    Device manager is also not related to the HDD's... and loading programs isn't always HDD bound, but usually is... either way. The difference between a fast mechanical HDD and a SSD is going to be a few seconds at most.

    ATTO benchmark is showing 500MB/s reads and writes which is pretty fast, considering most mechanical harddrives top out at 100-120MB/s and slow down when you get to the outer edge of the platters.

    One thing you can try is if you are using the onboard Intel RAID controller, you can download the Intel Rapid Storage Technology application and enable write-back cache. There is a risk if you lose power to the drives that you will corrupt/lose some data but it's a lot faster. My systems are backed up every night and hooked up to a UPS so I don't really have any worries. At least for me every time I enabled write-back cache on a set of RAID drives my performance went up a lot.

      thanks jbuschdev,

      hi Ronald,

      you can use HDtune to see the version of firmware, and you can updgrade to 2030 if it's not.

        Thank you Jbuschdev, I installed the Intel Rapid Storage Technology application and enabled write-back cache and it shows faster in the benchmark.

        Gskill Administrator, I have the disks in RAID 0 and I cannot see the firmware version. I also tried CrystalDiskInfo but it's the same problem. How can I check firmware of SSDs in RAID 0? And what will updating firmware improve? Thank you.

          Hi ronald,

          sorry, i was typing wrong name of your phoenix pro firmware, it should be 4.0, not 2030.
          as the image you showing, the speed looks fine, you don't need to do anything about it.
          again, sorry for the mistake.
          you can use HDtune to see the version of your firmware.
