Was thinking of using raid 5 setup with 3 harddrives does this have the pros but non of the cons from a raid 0 setup
thanks for the help

If you use 3x 1tb drives, you'll get 2tb in raid 5

You can survive one drive death

The write speeds for RAID5 will be significantly less than those for RAID0 unless you spend a daft amount of money on a high end controller card due to the parity calculations required for redundancy.

I'd assume that'd affect read speed too, since you've got to calcuate the answer for checking.
With a fast CPU and software RAID 5, I'd think it was negligible.

made a mistake
