    My raptors are slowing down... *56K

    well, after reinstaling windows, I decided to do a few benchmarks, what I found out was shocking! I still remember when my raptors were capable of sustaning a read of 102Mb/s... But now its some where around 50Mb/s!

    PLEASE HELP! Well, I guess what I'm asking is what afects the read and write speds? Drivers, block size... ect. And what is causing my nightmare?

    First off wow keep the pictures smaller please - I am running 1280 and had to do some serious scrolling across to see what was going on. Resize and repost the first and second pic (640-480 is more approriate)

    Secondly what difference did you do when you reinstalled? New drivers? Different block size?

    well, my LCD has a native of 1600, by 1200... When I went to resize that giant image to a decent size the text became too small to read! Sorry...

    But heres the 640 by 480 you asked for...




    Its a hardware raid on a sil chip, I never had this problem before, So I might do another reinstal!

    If it's a fresh install you should be getting more than you have. You'll need to check that you've them set to Ultra DMA mode 5 and that you've got the latest chipset drivers and also the latest Intel Raid accelerators drivers. I seriously doubt the drivers have physically slowed down. Out of interest how full are the drivers?

    my raptor raid is alitle over 65% full... Heres the funny part, thery not slow! They just bench like crap! Also there is the sound of constant hard drive activity coming from them! However the light on my case is not blinking... This sound of seaking never stops! Is there a program I can use to determin what is constintly useing my drives> like what app is acsessing what and when? I have indexing service off, also system restore... So I know its not them... Oh, and yes there at udma 5.... I have tried evrything I can think of!

    I doubt you're getting any real world performance increase from having them striped anyway (whereas IMO you'd proabably see some improvement if you just strategically arranged the files on them - e.g. drive 1 as boot drive, drive 2 for apps / page file). Having said that if you've re-installed windows are you using the same drivers as before? If one (or both) of the drives is constantly working - maybe it's trying to sort itself out - so if you can why not test both drives separately before you've installed so much that it makes it a PITA to do this. Also - 5 year warranty - so no point in selling them on. If you do RMA one or more be aware that you get refurbed drives back - TEST THEM THOROUGHLY - I had a couple that I RMA'd and got duff drives back again (which were subsequently replace with NEW drives IIRC).

    All ATA drives (even SATA) start to slow significantly when they start getting 50%+ full. You should use your Raptors for OS and a small number of commonly used programs only and keep the rest of your programs and data on the other drives.

    I was just reading an article on the MSI forums about Raid 0 performance with Raptors on the K8N Neo Platinum.

    Its been proven that a 16K block size is best when setting up the Raid array. The graphs go from jagged to nice and smooth.

    I'm going to reformat when I get chance as my rig (see below) gets similar graphs in those benchies.

    The 16k stripe is only good for benches. 128K is recommended for best desktop overall performance.
