So I'm looking for a storage solution which will allow me to maintain high performance whilst gaming and recording to a harddrive/hard drives using the program fraps. Currently my frame rates drop significantly whilst recording, and although I've improved these somewhat with playing around with the affinity of my processes, moving fraps to run on both cores worked best, I still get low perfomance while recording and I've been advised that this will be because of recording to the same hard drive as everything else runs from.

My question is, what would be better to use for this perfomance, a single 10k sata drive or a raid setup of some kind. If raid would be better, which hard drives are best for this purpose at the moment, I don't need a load of hard drive space 150gb would be ample space, and I'm not overly bothered about security of the drive setup. I just want the quickest write performance I can get which doesn't lag out the rest of my system, fraps fills up about 1.2gb per minute of footage

Thanks for any help offered

ps my system is a core2duo 6600, 2gb ram, 8800gt gfx, asus p5b deluxe motherboard. Currently using a random assortment of sata II, sata I and pata drives. have space for 3 more hard drives in my chassis and plently of sataII ports remain
