At some point in time, a disk will fail. It is the performance of the
array during recovery that is very different between RAID5/6 and RAID10,
as to recover one drive in RAID5/6 you need to read from a lot of
drives. Also with RAID10, you can have multiple drives fail and as long
as they aren't

As the person who asked the original question,
The performance limitations of RAID5 or 6 vs RAID10 are mitigated by the
number of spindles. If you have 8 or more drives in your array, the
performance difference disappears. This, of course assumes a true
hardware RAID controller and NOT software.

For only serving POP3 there is no such hardware requirement.
We do 10K customers with standard hardware, and software raid (5).
(although on postgres).
We have sendmail on a different machine, but dbmail runs completely
on 1.

OK, before a disussion starts, I need to say that RAID 6 is important
for us (high security), and also performance. With these tests, I'd
recommend Areca. Maybe you have another needs to prefer LSI.

All your questions depend highly on the hardware, so there's no single
answer. A standard desktop might have problems with that load, but a
server with some real hardware RAI
Hi,
I've just started looking at dbmail because of its scalability.
I'm wondering if anyone out there can provide information about the
a MySQL server's needs -- how well can it scale with dbmail? We're
looking at about 9000 accounts and ~1GB of mail delivered locally to
mailboxes
