I am installing Win2k8 on a system with 6 hard disks. They are 1Tb in size each. I want to create Raid 5 with 1 hot spare. How much disk space will the raid contain and how much space will Win2k8 see if formatted using NTFS? Explain if any disk space will be lost and why?

this is not really in the correct forum. With that said you lose one drive in a RAID 5 configuration. Windows 2008 R2 can see partitions larger then 2TB if that partion is formated with GPT. Here is a calculater to help you figure out how much space you would be losing. http://www.ibeast.com/content/tools/RaidCalc/RaidCalc.asp

Thank you. I am new to this and am in school trying to learn a bit about it.
