I have 2x3TB Seagates which have a pretty good read/write throughput, I was wondering if I would get a performance increase if I partitioned say 250gbs from each drive and made a RAID-0 array, I havnt really done RAID so im unsure how it works and if this will work. If this does work I plan to mirror this on 2 of my 1.5TB's so I don't have to worry about failure.
Any thoughts ?

If you plan on striping and mirroring, why not just go with RAID 10? Also, when using RAID, it helps if all drives are the same size and preferably all the same make/model.

For best performance, get a SSD. Also note that RAID is not a backup, it's for redundancy. You will still need to maintain good backups.

Yes basically a RAID-10. since I had 2x3TB drives that are identical, and 3x1.5TB drives that are identical. But I don't need all 3 TB's to be striped, only aobut 250gb of each making 500gb total, which is pretty much my OS+Apps+Games .... and then 2 of the 1.5TB's for redundancy and 1 of the 1.5TB's for backup. Would this be a good idea, or wont I get much performance from taking 250gb section from the bigger drives if they are still using the remaining 2.75TB's for mass storage ?

This is pretty much what I was trying to find out ... Damn :(. I guess ill be trying it with the 1.5TB's then, since I cant wanna risk 6TB system failure haha. I don't really like SSD's for the price at the moment where im from its hard to justify it to myself.
