one big array, or a boot array and a (less big) array ?

[Arone Silimantia]

I have a system with 8 drive bays.  I have 8 250 GB
disks.

I would like to just create one giant raid5 array in
my adaptec hardware raid controller of size 1.75 TB,
and just make my partitions (/, /data, /var) on that
big 2 TB array.

But I feel like I have heard suggestions on this list
before that one should have a separate array just for
the boot and userland, and that the big monster array
should be separate from that.

So instead, should I take two of the 8 disks and make
them a mirror, and put boot/userland on there, and
then  make a raid5 out of the remaining 6 ?

Or does it not matter at all ?

If one is better, why ?  Thanks.
