doh! I hadn't thought of that. Thanks. Software it is!
I have an existing setup that uses four 120G drives in software
RAID 5
under windows 2000, and I learned that it's best to have exactly the
same kind of drives. Mixing WD and Seagate caused problems. Is that
a RAID 5 idiosyncrasy or a windows thing?
I've heard it recommended for any RAID, but I've never had a problem
under
Linux sw RAID with differing brands of drives.
Two drives from different manufacturers that are the same advertised
size may not have exactly the same formatted size. This isn't a
problem when you create an array; the extra space on the slightly
larger drives is just wasted. It can be a problem if you have a
failed disk and the replacement drive is slightly smaller than the
others, however.
3ware SATA RAID controllers get around this by reducing the size of
all the drives down to some safe value, to ensure they'll all have the
same apparent size.
