yeah, what Ed said.  Had a problem like this pop up on a SAN connected
server after a round of mailbox migrations that pushed it up to 2000
users.  Turns out when the server was built (before I had started) the
email architect had no say in how the SAN was set up for this server,
the SAN admin just took 4 very large drives and made a RAID 5, then
carved that up to the desired amount of "drive letters" the exchange
architect asked for.  5 mail stores running off of 4 drives, disk I/O
was completely choked.  I always use the perfmon counters Physical
Disk | Avg. Disk sec/Read & Avg. Disk sec/Write to check disk I/O
performance, though you should get a good baseline from a normal
acting server to see what it should look like.
