a. Has anyone used iotop? thoughts?
Implemented in Python, so it's a toy. Was*the* thing back in 2.6.x
kernel's days.
b. Can anyone recommend a different tool?
"iostat -kx 1" to pinpoint a drive.
"pidstat -dl 1" to point at a process eating I/O.
Both come with "sysstat" package.
"perf top", but it*does* require skill, knowledge and determination.

There you go!
Good answer.
I saw the python in iotop as well and had doubts from there.
If it was an ext4 drive on Linux, I'd be thinking lazy ext4 init,
I'm looking at hdparm -C too.
Thank you Reco
