I am struggling in vain to set up a RAID 0 array on my PC and am failing horribly. My motherboard is a standard Dell E521 and only supports RAID 1(Mirroring). So I brought a RAID adapter on Ebay (Cheap only about £5) and it will not work. The software for use within windows doesn't detect the card, and I dont get an option during bootup to set up a raid array either. It does work as appears in device manager and all drivers seem to be installed correctly. Also the disk I got with it did have the drivers for OS installation process, which I have tried and was the only time I managed to get my PC to realised the thing is actually plugged into it. But as I hadn't managed to set up the array it just showed two separate HDDs.
Is it worth getting another to save the agro? I know the decent ones are pricey and I wont be paying more than about £25 for one. Or perceiver with this one!?
I always advise to NEVER put the OS on an AID0 array. When the array gets corrupted you'll have to reload everything. I realize your trying to spend a tiny amount of money to get a big leap in performance, but its not going to happen. Even if you get those drives AIDed, your CPU and GPU are so low end these days that they will hold everything back. You got a good net machine, but it will never be a good gamer with those specs.
Edit: Forgot to mention. If you just want it feeling "sharp", then sell one of the 500GB drives and pony up some more money and buy an SSD. Put your OS on the SSD and it should feel sharper for day to day tasks.
