RAID 1 can help us?

Specs: Windows XP, Xeon 3440/ 4Gb
Hello guys,
We have 3 Dedicated servers Xeon 3440 with 2 HHDs with each server.
OS: Windows server 2003 Standard Edition
disk0: Using for OS and MY SQL Enterprises with applications
disk1: is for RAID *Blank

I need to know what method we use to RAID disk0 to secure our data from Hard disk failure and what to do if disk0 failed?

Thanks

Two steps:
1) Get a RAID 5 going.
2) Backup as if your employment depended on it. Because it does.

You can't do raid5 with two disks.

anxious since you mention no raid controller I have to assume you are doing to raid1 with dynamic disks.

Web search converting basic disk to dynamic and then dynamic disk raid

I didn't say additional purchases wouldn't be required. (He didn't mention any backup capable hardware / backup services, either.) A good RAID card, extra HDDs, and a rack mount server case with hot-swap bays would cost, what, about $1000 a pop (plus downtime and labor for the install/configure)?

Obviously, he should compute the ROI before making any real decisions. (How much money a day does the business loose if this server is dead?)

Thanks for you quick responses, im so far thinking about Software RAID1 from Disk management but i never exactly know what to do if one of my hard disk failed?
We are using these server for Voip, the Data is all in MY SQL RAID approach is to save time for reinstalling OS and other applications etc.
We also looking for some kind of replication so the MY SQL data should be save on backup node server.

Important: In MY SQL data entries are fast enough update every second so the backup replication should be mirrored.
