iotop does for I/O usage what top(1) does for CPU usage. It watches I/Ousage information output by the Linux kernel and displays a table of current I/O usage by processes on the system. It is handy for answering the question "Why is the disk churning so much?".

Package page: http://maemo.org/packages/view/iotop/
This is actually latest iotop (official site), with some UI modifications to make it more usable on small screen. The process name was moved to the left part of UI and if you increase the terminal size, it will drop some additional information out, but keep name and basic IO info.

See more on screenshots:
Optimized interface:


Minimum font size:


Maximum font size:


Only active processes mode (toggle by pressing 'O'):


Please, refer to official iotop documentation for usage help.
Install:
Code:
apt-get install iotop
Package is in extras-devel yet.
Note, it's written in python. It will be installed automatically if not installed.

Guys, i am noob at this, I/O stands for operations made with memory, not RAM, right?

Bit of a bug - got this when I tried to run it:
Code:
N900:~ $ iotop
 -bash: /usr/bin/iotop: /scratchbox/tools/bin/python: bad interpreter: No such file or directory
So I edited line 1 of /usr/bin/iotop so it reads:
Code:
#!/usr/bin/python
And it now works

Alfred - I/O stands for "Input/Output" - all hardware does it in some shape or form - disks, RAM, keyboards, video cards, usb sticks, printers, etc etc.

I get the error:

Could not run iotop as some of requirements are not met:
Linux >= 2.6.20 with I/O accounting support.

Oh, I'm afraid it only works with kernel-power kernel.
Will add it to dependency, thank you.
