I'm building a new computer over the summer. I'm fairly competent in computer hardware, and am thus building the computer from scratch. I have everything planned out, but I was wondering if I should consider RAID, and if so, which RAID to use. I plan to purchase 2x1TB drives. Currently I'm leaning toward RAID 1 for the redundancy -- I've heard newer super-capacity drives fail more often than one would think, and I don't want to have a problem and lose all my data. What do you think? My mobo supports RAID 0/1/5/10. Is it worth it to use RAID at all, or should I just use a backup service like Mozy? Should I consider RAID 0 instead, for the performance? I'm kind-of going back and forth on this one. Thanks a lot for your help.
EDIT: I'd like to avoid the OS drive different from Data drive situation, because that can get frustrating when programs like to store a lot of data in their program files folder. I've lived with that situation before and it gets annoying after a while.
6Newer large drives do not fail more often than others, you just lose more data when they do die with no backup. – Troggy – 2009-07-23T17:27:29.117
From your question, it already appears that you have a good understanding of basic raid, so i've got nothing to add there.
That said, i do have some anecdotal information. I wanted performance and reliability. So i chose a pair of enterprise grade drives (Western Digital Raptors) that were fast (10k RPM) and ran them in raid 0. I ALWAYS made sure i had copious amounts of cooling on these drives and have NEVER had a problem with them. This was almost 5 years ago and i'm still using them today. – NoCarrier – 2009-07-23T17:28:31.703
1Sorry to bust your bubble, but the WD Raptors are not enterprise grade hardware. They're damn fast drives though. – Paul McMillan – 2009-07-23T21:16:02.673
Can you describe the problems you've had with programs installing data into the "Program Files" folder? Is it to do with games? – sblair – 2009-07-26T01:50:39.557
Mostly games, yes. But I think ~300GB should be enough. I'm thinking about going with a 300GB 10K rpm drive for program files and one 1TB drive for data. – NickAldwin – 2009-07-26T03:26:25.207
