My system drive just died on me after 2 years, a Seagate U320 Cheetah Scsi. I was thinking of doing a Raid setup with some WD Raptors. I was looking at raid 0 and 1 but the choice was performance or redundancy. I was thinking of going Raid 5 for my system drive with 3 drives and keeping the 4th spare, maybe using it as a video drive. Would this give me high performance? I don't want to even see the Windows startup screen.. heh. are the seek times good with Raid 5? I also do 3d modeling on the station so I have gigs of texture maps that need to be called on too.
My opinion.. AND it is my personal opinion on OS drive setup, is to never RAID it. If the RAID 0 goes down you are SOL until you fix it. I personally suggest finding the fasteset single drive. (if you want a redundant RAID, I wouldn't say no to that, but it doesn't increase that almight performance you are looking for.) If you want better performance get two+ seperate RAID setups for, 1) video, 2)scratch, & 3)audio or texture maps. (I could always mention the CPU and memory to boost your performance, but since you didn't ask I assume you already have addressed that.)
74 G Raptors in RAID 0 is an excellent choice for your Boot drive, since they are quite reliable, and ultra fast. But Lee is right that if one drive goes down, you're in trouble. RAID 1 slows them down so you may as well have a normal 7200 rpm drive. I use a 36 G Raptor for boot (the 74G version IS slightly faster though), and put Doc and Settings on a Maxtor Diamond 10 for D: Drive. I use 74G Raptors in RAID 0 for video capture and that is amazing-you will NEVER lose a frame. RAID 5 is also an option but if you search around you will find an abundance of controller card/SATA issues that must be resolved. I haven't seen the windows startup splash screen for years so if you don't need to eneter a password, search for XP tweaks and tips and you'll find out how. If you don't, ask again and I will tell you how to do this. Good luck!
