I think that you will find that ZFS's equivalent of RAID 10 (load-shared mirrors) works very well. I can't imagine any reason to rely on a RAID array to do the mirroring since ZFS will do it smarter, better, and more reliably.
If you go for raidz for bulk storage, then you should consider using raidz2 for the extra security and peace of mind.
Once I find this what is the average rebuild time on raidz say a 1tb sata disk. And finally what kinds of cards will I get the best performance from for the use of raidz. Or does it not really matter.
I don't know if there is any average time for this. The time depends on how full the disk is and how fragmented the metadata and user data blocks are. It also depends quite a lot on the disks you use.
