Hyper-V on Raid 5

Hi All,

Has anyone had experience implementing a small Hyper-V solution on internal 15k SAS drives, configured in RAID5. Do the write overheads cause delay/Degradation in performance to the overall environment. Is the cost per MB worth the jump to RAID 10(or RAID 0+1)? This is for a small solution, and a SAN/Storage array is not on the cards,

I appreciate any feedback, Thanks in advance!
