Hello,

I will be setting up a PC, that has to be fast and secure. They
recommended Raid 10. I have a question about Raid 10: If a data drive
fails, can the second data drive be removed from the Raid PC, and installed
in a PC without any Raid?

Thanks,
Talal Itani
 
No, you can do that with RAID 1 only.

Dear Friends,

I just learned about the Intel Raid Matrix. This sounds interesting. Have
you used it? What do you think?

Thanks,

The answer is no.
Raid 10 is a combination of first Raid 0 (striping) and then Raid 1
(mirroring). So you benefit from the advantages of both systems. But because
you first stripe, and then mirror the striped disks, each disk is a striped
unit that cannot be used alone in another system. However, if one (striped)
disk fails in the original system, it will always have a mirrored disk and
data will be retrieved.
Note also that due to its configuration, Raid 10 requires minimum 4 physical
disks.

I recommend that you use a Raptor for the OS and two drives
set in RAID1 for the data (and some applications, depending
on your use of the system). That's 3 drives total.

The Raptor w/operating system would have a size limited
partition for the OS and a backup made of that. Store the
backup on the RAID1 array if you find it convenient, but
ideally put the backup on removable media.

You don't mention the use of the system nor the budget
though, so your questions have no context. Remember that
all of these possible drive and RAID configurations exist to
suit different contexts. There is no one "best" way to do
*everything*.
 
I have not used Intel Raid Matrix. It seems like a good idea if you are limited to 2 drives, but it will not have the performance of separate RAID 0 and RAID 1 arrays. If you are going to use 4 drives it seems to me that having a single RAID 5 or RAID 1+0 array would be the way to go.
