Building a video editing system for a mate and am thinking of clocking the CPU to 3GHz to give him better times on rendering/encoding video.

DS3P and a E4300, going to run the OS in raid0 so he can get good access times from his online files.

Will also include a 500GB drive for offline files not running on the array.

I've heard that you can get data coruption on drives when oc'ing and running in raid. Any truth in this?
 
Two ways you can get data corruption (and not neccessarily just to RAIDs).

1. Unstable overclock

2. The bus the controller is on isn't locked so it's overclocked as well - most MBs these days will lock the PCI-E bus or whatever bus the controller is sitting on/

Yes - NVidia RAID arrays are especially prone to this and it's more of an issue with SATA than PATA drives, but really, you're better off with a proper buffered card for RAID, and ideally a SCSI card as this is immune from the problem.

It's utterly amazing how cheap you can buy 4 9Gb SCSI HDD and a SCSI RAID card at auction. And they'll eat a 4-way Raptor array for breakfast inm terms of performance. As it's just a boot//cache/OS drive 18Gb or even 36Gb would be plenty.
 
will be using the gigabite DS3P and a E4300 I've heard good things about the clock speeds with this combo, the on board raid controller will be used, has anyone ran into corruption with this setup?
 
Well, it's ICH8R, so it should be OK, but a single Raptor will almost certainly be as fast as 2 drives in RAID0.
 
indeed a single raptor would however 150GB raptor is a bit pricy compared to two 320GB drives.
 
as mentioned the system will be used for video editing so the original footage will be stored on DV Tape, the RAID0 array will be used for online files, I'll have a seperate 500GB drive for offline files and the project files, if a drive crashes I'll just use a ghost image to restore the system. All critical data will be on the tapes/archive drive.

150GB raptor ~ £155.29
2x 320GB segate's ~ £101

computesss to me. :p
