I know there is a lot of debate on the issue of RAID and putting OS on its own array.
I'm currently considering the purchase of a Dell T410, 24GB RAM, 6 250GB SATA Drives and X5660 processor. Getting SBS 2011 for about 25 users (no SQL needed)
I have one consultant who recommends RAID 1 for OS and RAID 5 for remaining 4 drives.
I have another consultant recommending RAID5 alone (performance)
I also see a lot of recommendations online for RAID 10.
Does anyone have an opinion on how SBS 2011 will do with RAID 10 (OS & Data on different partitions but same array)? I think we can afford to give up 50% of the disk space if its worth it.
