We are getting ready to purchase two new servers for our network, and upgrade our NT 4.0 servers to Windows 2000 Server. For our two domain controllers, we are leaning towards deploying Raid 1 instead of Raid 5. However, I am not as familiar with Win2000 Server and wanted to know if there would be any advantages to using Raid5 than Raid 1 (besides the obvious backup advantages). For example, are there any features that Win2k offers that can only be used if you use more than two disks with Raid1?

Thanks,
Dan

The relative advantages/disadvantages of a given RAID implementation will be the same for Win2K as they were for NT4 (I'm assuming you are talking software vs. hardware RAID). One change from NT4 is that in Win2K, in order to create any kind of fault-tolerant volume, you must change your disk type from basic to dynamic. This is done from the Disk Management tool.

There is one problem with RAID-1, it's not recognized by Windows 2000 Server. In the Sybex MCSE 70-215 Windows 2000 Server book, on page 270, it says that only RAID-5 is usable in Windows 2000. I would stick with RAID-5.
