RAID 0 rate of failure increases (N-1)/N. Two drive increased the failure rate by 50%. One drive fails, cable comes loose, power sags on one drive. You lose your RAID array and data. How do you backup 2 TB?

"People who don't back up will at some point, live to regret it, I assure you. It's happened to me." Happened to me too. BUT the thing did run hard for over a year without an issue. Now I have an external drive.

I have the followings: MB: Gigabyte GA-EX58-UD5 CPU: i7 920 Mem: Corsair TR3X6G1600C8D Dominator 6 GB@1600 HDD: 1 X Seagate 1.5 TB (win7-64 boot drive) & 2 X 2TB Hitachi in RAID0 I want to optimize the raid0 array as storage for Windows Media Center HDTV recordings and for HD video processing (e.g., mpeg-2 -> mpeg-4 transcoding, etc.). What is would be best for the RAID 0 stripe size? (128K is default) What would be optimum for the...

512 KB block size normally will give you your best performance size.

One fatal error in RAID 0 means you have to format the drives and mirror over your backups, you cannot use one disk from a RAID 0 array without all the others. One error will not kill the other disk, but the date will be un-usable. You are thinking of RAID 1, if one of those die you will still be able to get the data from the other disk, or install a new disk to mirror the other disk on to.

Indeed. RAID levels are complex. To be honest it's not going to be such an impossible job to backup a 2TB RAID0 array. Why? Because nobody on earth as a mainstream user RAID 0's two drives then immediately fills them to capacity. There's also nothing stopping people from adding to their backup drives when necessary. A tip is not to buy 2TB drives, but get 2 1TB drives. In fact, for the price of a single 2TB WD Caviar Black, you...
