Please Recommend RAID 1 setup

I have a small office with one computer, and I'm about to add another for a simple peer to peer network. I need to do something to backup my data. RAID is the method of choice around here, so... Can anyone recommend a basic RAID 1 setup? My computer's a Dell (about a year old) running Windows XP professional. I'm not completely clueless, but clearly not as computer smart as the people here. (I'm certainly capable of installing cards and drives, and doing basic configuration, but that's about it.)



What should I buy and where should I get it??



Thanks in advance for you time and help.

Get a basic RAID controller (most will give you RAID0, RAID1 and maybe even RAID0+1). Plug your drives into it and then when you bootup, the RAID BIOS will give you the option of making RAID configurations.



You can get Promise controllers fairly easily/cheap. I personally dont like them much and usually huntdown Adaptec or Highpoint but thats just a preference
