[linux] software RAID-1 query

[Joel Johnson]

I've also had great success with sw RAID. Since you mention it will be doing more read than write, you'll get the benefit of reading from both drives.

One nice thing that I've had to do with sw RAID as well that was nice - you can use whatever disks you would like (different sizes, etc), just the partitions are what the raid works with.
