RAID set-up - good idea?

[4BwlNvvHufcy]

I'm thinking of copying this guy's set-up:

Any reason not to have RAID-0 and RAID-5 on the same disks? Seems like a good way to have performance on one volume where the data is replaceable, and have redundancy on another where the data is... less replaceable. Though, RAID is not a backup. I know this.

Good idea/bad idea?

I'd just RAID 10 four drives, but that's just me.

What are you trying to accomplish?

Speed on the operating system/program/game volume, and some redundancy on another.

For that goal, you should use separate drives. Have swap and/or temporary files on one independent spindle and have the OS on another. If you have more drives, use more independent spindles for other stuff. Then backup your data (maybe using Amazon S3 or DropBox, etc.).
