Hello Ken

Thank you, I have RAID 1, I have (2) 500GB Drives but they act as (1)
so if the primary hard drive fails the secondary drive takes over.

You're welcome. But if the purpose of having RAID1 is as backup, as I
said earlier, it's a very poor approach to backup.

In fact, my view is that RAID1 is almost never a good thing for a home
user to do.

Are you sure you mean Raid 0 Here? that will not give you the
option you may want

disks will be lost if any one disk fails. > >

That's correct, except that in practice RAID 0 usually proves either
*no* improved speed or such a tiny amount that it can be ignored. The
one thing it mostly does is dramatically increase the risk to what's
on the drives; that tiny increase in performance (if any) is not
the greatly increased risk.

I completely disagree.

Most people completely misunderstand what RAID 1 is all about.
RAID 1 (mirroring) is *not* a backup solution. RAID 1 uses two or
drives, each a duplicate of the others, to provide redundancy, not
backup. It's used in situations (almost always within corporations,
not in homes) where any downtime can't be tolerated, because the way
it works is that if one drive fails the other takes over seamlessly
and almost instantly.

Although some people thing of RAID 1 as a backup technique, that is
*not* what it is, since it's subject to simultaneous loss of the
original and the mirror to many of the most common dangers
your data--severe power glitches, nearby lightning strikes, user
errors, virus attacks, theft of the computer, etc. Most companies
use RAID 1 also have a strong external backup plan in place.

Read my thoughts on backup here:
'Back Up Your Computer Regularly and Reliably'

Also read here: Why RAID is (usually) a Terrible Idea
'Puget Custom Computers: Why RAID is (usually) a Terrible Idea'

using two (possibly more) disks that each store the same data so that
data is not lost as long as one disk survives. Total capacity of the
array is just the capacity of a single disk. The failure of one
in the event of a hardware or software malfunction, does not increase
the chance of a failure nor decrease the reliability of the remaining
drives (second, third, etc). > >
