usable will be 6TB, you won't be able to boot to it.

There is a 2.09TB limit on MBR-formattd disks, and MSFT requires you to have an itanium-based system to boot from a logical drive that big.  There are some things being done with new BIOSs, but if you had such a machine you would know it.   Plus software RAID-5 wont be bootable anyway, as the XOR parity stuff is being done by the windows O/S.  But the windows OS has to be booted first :)

May i suggest just building 2 RAID1s?  Then you can boot.   Otherwise you won't have a protected boot disk anyway.

The limitation is on the boot volume. You can't boot to a larger volume than 2TB.

So, adjust your boot partition under this limit and should work.

Correction, software RAID5 is bootable in Win2k8, but performance will be horrible.  Rebuilding will take days.  Reconsider
here is one of many writeups warning against it
