Best practize to store the ZONE files

It's really more of an OS tuning question, isn't it?

The usage pattern of a BIND instance is:
a) not much writing of master zone files or journal files unless Dynamic 
Update is enabled and the frequency of updates is relatively high,
b) not much writing of slave/stub zone files or journal files, unless 
the zones have aggressive REFRESH settings and frequent updates
c) not much reading of zone files except at startup or restart/reload, 
or possibly whenever writes occur, to read the zone data back into memory

Now, given the usage pattern(s), how best to tune performance, based on 
the capabilities/limitations of the underlying OS and hardware? Same 
partition and/or filesystem versus separate partitions and/or 
filesystems? A different type of filesystem? Is the disk storage RAIDed? 
Striped? Mirrored? Is a journaling filesystem in use?

Older filesystems used to run into performance problems when directories 
got really large, so some folks used to split up their zones by the 
initial letter of the zone name, e.g. "zonefiles/a/", 
"zonefiles/b/". I don't know if that's still an issue with 
modern filesystems though. We've never had more than a few thousand 
zones, with relatively rare restarts/reloads, and most of the zones not 
changing very frequently, so we haven't noticed any problems, and 
haven't resorted to any "special" setup for storing zone files.

It occurs to me that the "journal" zone-level option in modern versions 
of BIND could theoretically be used to group all of the journal files 
into a separate filesystem/slice/partition, which might be better tuned 
for frequent updates, than the zone files themselves, which would change 
relatively infrequently. I haven't tested this theory though...
