It sounds like you have done fine with what you have - I don't want to say
that "your" config is sub-optimal, and as I mentioned, with only 20
mailboxes, it won't be an issue. Here is the optimal config that I have
come across for Exchange
2x hard drives RAID1 for OS
2x hard drives RAID1 for log files - RAID1 gives better performance because
log files are sequential writes.
3(or more)x hard drives RAID5 for databases. You could also configure RAID
10 here for optimal performance, but that is expensive disk-wise. RAID5 is
chosen here because it generally provides better read performance than RAID1
(RAID0 is the best, but who's going to use that?). While it isn't as good
write-performance-wise, RAID5 offers the additional fault-tolerance with
less of a cost disk-wise.
The reason it is usually important to have 3 partitions is that the log
files should be separate from the OS, but also separate from the databases.
The reasoning is simple. If your log files start growing out of control and
fill up the disk where they are located, if they are separate from the OS,
then while the databases will dismount, your OS will not crash. Also,
keeping them separated from the Databases protects you if you lose the raid
array where the databases are located, because you can restore from tape and
Exchange will then replay the log files to get you current with no loss of
data.
