Yes but for disk drives I/O (number of read/write ops) are the key
resource usage information. It's very hard to setup a billing model
for disk drive usage on bandwidth as low bandwidth disk operations
(small random read/writes) can utilize disk drive more than huge
sequential reads/writes. I need also to mention that AWS is also
charging for I/O in their volume service.

Yes. Just give me few days.
