Finally bit the bullet and I am building an old aluminum/magnesium case that I customized years ago, with new guts. I plan to use RAID 0 in the unit. Here's the specs: Intel E6700 2.66 Patriot 4Gig DDR2800 6400 in 2 sticks EVGA 8800GTS ABIT AB9 QuadGT Zalman 600w PSU (modular) 2 Hitachi 500GB Spinpoint 7200RPM SATAII drives (3.0 Gb/S) I've deployed multiple readymade RAID5 solutions in the past on my gigabit network and they've performed flawlessly. This is the first time I've deployed RAID0 in a non-NAS app (i.e. desktop box with the OS), and I'd like to hear tips/pointers from you guys if you've done this before. As a "for instance", I've researched that Windows doesn't like RAID0 natively, and I need to boot from floppy and install my RAID drivers before I install the OS. I'm sticking with WinXP Pro for now, no Vista for me yet. Looking specifically for tips on RAID0 optimization... Thanks for your thoughts.
