How to configure raid with 3 sata hdd?

Question

2 hdd- raid 1= data
1 hdd- raid 0 = OS

Answer 1

You cannot have RAID 0 on a single disk, so the OS disk will be a simple disk volume on a single disk.



You do not mention what operating system you are using or whether the computer has a RAID controller. I am going to assume you want to set this up as software raid under XP.



1. Convert the two disks for RAID to Dynamic Disks.

2. Set up a RAID set on the first disk.

3. Add the second disk.



I am including a link for a tutorial. There are a ton of other tutorials online to describe the process.



Good luck!

Answer 2

It takes 2 HD's to run either Raid 0, or Raid 1. You could run Raid 5 with 3 HD's. I'm a fan of Raid 0. It's faster. You might set up a Raid 0 system with a spare HD for backup storage.

Answer 3

You need 2 hard drives for Raid0

Use the 3rd hard drive as a non raid for storage.
