If you are issuing INSERT or UPDATE queries, you should expect disk

What units is hd-write in? If you're graphing the net-snmp diskIOTable
values (diskIONRead and diskIONWritten or the preferred 64-bit
counterparts diskIONReadX and diskIONWrittenX), they are in bytes.
2400 sounds either way too low if your units are KB/sec (==2.4 MB/sec),
or way too high if it's in MB/sec (==2.4 GB/sec).
