robo989 Posted August 10, 2005 Posted August 10, 2005 Hi, although my mobo went knees up today, its gonna get replaced pretty quickly and when it does I'd like to find out whats causing this strange behaviour on me raid0 array.. Righty, I got 4 of those new hitachi sata 2 drives 250GB versions in raid0 on the nvraid controller. They have all been unlocked for sata 2, sata spread spectrum, power managment has been disabled, acoustic management has been disabled, and so has smart. So basically they should be as fast as they possibly can be. They act the same with ncq onoff... Here's how I can describe it... Imagine you have only 1 hard drive but it is partitioned into 2 seperate partitions and then you copy a large file say 1GB+ from one partition to the other, you'll noticed windows is really sluggish, even right clicking the desktop and clicking properties, you'll be waiting a good 5 seconds+ for the properties page to appear? Ya with me, and similarly just double clicking my computer and there's loads of disk activity... The stange thing is that their actualy ability to shift data at high speeds doesn't seem to be affected that much and the behaviour only happens after loading a lot of info from the drives... Its as if virtual memory is being used? I just don't get it, I'm using decent sata cables, have tried both the original cables and some supposedly good "Akasa" ones, well they were expensive anyway. its a real downer this, it feels like I only got 256mb ram in the computer, 1GB should be more than enough, its not even using it. Is there a way to force windows to stop trying to cache everything in virtual memory. It also seems that the nvraid controller is using alot of cpu cycles... 1 thing tho, I am using the original .475 raid drivers for windows x64 do they have any issues. The thing is you need to reformat to upgrade the drives so I haven't tried others but I doubt its that, anyone elese getting this or can help me? thank you, any suggestions and advice is greatfully accepted Rob (I mentioned this before but I didn't explain it well so sorry for repeating it) Quote Share this post Link to post Share on other sites More sharing options...
