Hi

When whs2011 finally arrives, I am going to install it in my current whs1 box.  Spinning away in that box currently unused is a dell perc 5/i with 4 one TB hard drives. in a RAID 5 configuration.  I was going to install the OS on this using the EFI bios system on the intel motherboard I happened to have in there, but I have chanced upon a few posts suggesting that putting the OS on the Raid array is a bad idea.  Would I then be better server to get a small fast HD for the OS (perhaps even an SSD from an older genration) and have the Raid array as storage only?

Cheers Ivan
