Chances are the RAID was setup at the hardware level not in Windows. If this is the case then you need to reboot the server and watch as it POSTs, for what function key to press to get into the RAID controller BIOS. Press it and the RAID controller configuration will open and it should tell you which RAID you are using. My guess it is 5 or 1+0 no one uses 0 or 1 any more.

Raid1 is used all the time especially for OS. It cheaper than 0+1 or 10 and has better read performance than raid5.

sanil thomas you would need to know the raid controller type and feature set. Some can rebuild raid arrays dynamically without a reinstallation of windows.

A way to guess what raid array you have is to post how many disks in the array. How many disks do you have?

True, but RAID 1 is not fault tolerant. I guess if I was building a gameing machine and only cared about speed RAID 1 would be the way to go. RAID controllers and hard drives are so cheap these days why not go with RAID 5 so you get a hybrid of both worlds.

Ace, raid1 is mirroring and is fault tolerant. Perphaps you are confusing raid1 with raid0 which has not fault tolerance?

A hybrid of both worlds 0 and 1 would be raid 0+1 which is not to be confused with raid10
