RAID5 Startup disk with all 4 internal drives?

[sandiegomatt]

4 Drives being better than 3, is it possible to setup my mac pro (2x3 Ghz Quad-core Intel Xeon ) (2008) with a RAID5 startup disk using the 4 internal bays.

I've scoured the web for 3 hours without any solid finds, has anybody actually done this.

And has anybody done this, then had a drive failure and was able to do a successful rebuild?

Thank you in advance,
Matt

I believe it can be done with the correct raid card and proper adapters on the inside that bypass the normal 4 connectors look for nano frog to give you an answer he posts about raid a lot and would know how to do it
