I know there are quite a few apps to show the space usage on the N900 and the external storage card.

But I was wondering how many widgets are there which show both the storage utilisations on the desktop ?

In particular I saw this one. Can anyone tell me which app is that which shows the space usage bar on the desktop in this screenshot ?

The ones I am aware of are

cpumem-applet - shows CPU usage and memory
Diskusage - not a widget - but a application (colors look horrible on the N900, was pretty decent for the N810)
load-applet - shows CPU and memory usage (no actual figures just graphical bars) .
systeminfowidget - same CPU and memory usage
