Its the one thing that seems to give us performance issues. Last time I investigated things running slow, client was quiet (low CPU short disk queue, minimal paging) , network was quiet yet response was slow. Conclusion was that server was some how bottle neck. I must admit I didn't do much work on investigation. I think they should use appropriate tool such as msde (only a few users) but program is provided by central government, so we are stuck with it. I wonder if it was just running same time as backups perhaps...

Access database will likely get cached on the client in memory, in any
case it’d be all read ops. Access doesn’t cache report output.

For file sharing, I would consider 0Ư but 5 would be more likely since
you
probably want/need the space more than the speed. File sharing doesn't
really beat the disks up relative to a busy DC even in large
multi-thousand
user file servers I have seen.
What about when some idiot user sets up an Access database on one and
runs "inappropriate" reports against it..
It is why most normal server admins really
have no clue what to look for in terms of IO load on servers but any
Exchange Admin worth anything is looking at that right away in a problem
situation and able to quote IOPS stats off the top of their head and
know
what they can get from the underlying disk subsystem. Exchange disk
configs
are critical.
