Hardware Raid or ZFS

Tomorrow I have 4 x DC600M 3.84TB disks arriving. The whole reason I am getting these is due to very slow restores when using HDD.

The question now is do I use hardware raid or zfs. I have a hardware raid card with BBU and also LSI HBAs so I can go with either.

Also in terms of raid level, I would generally always use 10 or striped mirrors using zfs.

Would using something like RAID5/RAIDZ have a significant impact?

Any input would be appreciated.

Thanks
