I was wondering if anyone knows if RAID 5 can be setup with WHS 2011 as the OS. I am going to purchase a HP microserver and wish to use 4 2TB drives in a RAID 5. I was possibly going to use FreeNAS however I am more confortable with a Windows OS. Does anyone know how to setup RAID 5, software RAID? I understand there would be a partition for the OS and would like to use the rest as usable data storage SANS the spare drive for redundancy. Any help would be appreciated.
