With a RAID1 it is mirrored. This means that if you write a file to 1 drive,
it will be added to the other. This will protect your system from going down.
If 1 drive fails, the other drive is working. This also means that if a file
is downloaded and is virused, it still will affect your syst

You actually can add raid to the hard drive where you have the OS installed
in most modern distros. Its a bit tricky in the old ones. The old ones
require that you install to a different hard dri

In litteral terms, you can do software raid on linux with 1 HD and two
partitions. However, it probably hurts performance, rather than improving
it. The multiple heads on a hard drive all line up vertically and scan
what's called a cyllinder (multiple sectors stacked on top of each other).
