Re: Expanding raid volume or any better options folks can recommen

RAID 5 should be faster (striping with parity on 3rd disk) than non-raid
(JBOD or 'dynamic'), slower than RAID 0 (fastest possible - striping only),
and faster than RAID 1+0 (same speed as JBOD with fault tolerance).
Personally I run two RAID 0 arrays, one with two 250 G drives for OS,
Programs, Pictures, and Music, and one with two 500 G drives for Recorded TV
only. I've run the 250s for 15 months continuous (no power off) without a
hitch. The 500s about 4 months. Life is a gamble... so are computers... if
one array dies tomorrow, so what! I've got my GHOST backups (OS and
important info only - NOT recorded TV or music ripped from my CDs) to
rejuvinate me (on an external USB 250)... :-)

Thanks, I've thought of it, but folks tell me raid 5 is slow which is why
I've avoided it, any thoughts on that? Also, I gather there is no easy
way
to protect the integrity of my setup and move to a raid 5 even via
cloning?
I'm trying to avoid a full reinstall because of the items mentioned above.

I have four 250 gig drives setup as raid 1+0 and am thinking of
replacing
these with four 500 gig drives. However, this seems like such a waste
of
a
terabyte and I haven't seen a MCE compatible partitioning software.

Run raid 5. One one drive is used for parity and the whole array is
protected from drive failure.

I installed a system with 10 drives once... A WD Raptor for the system
drive
and eight 250gig maxtors in raid 5. The last drive was mounted in the
chassis so it could be put into service if a fault was detected.

This meant we had 1.75TB on the array available for use.
