What it does

Shows used and total space with a percentage bar, plus read and write throughput in the header, measured per drive, not system-wide.

Select one drive and you get the full single-drive view: space, a bar, and two overlaid sparklines (read in green, write in accent) scaled against a shared maximum so the two rates are directly comparable. Select several and the widget switches to a stacked layout with each drive’s space bar in turn, scrolling if they outgrow the widget.

Clicking a drive opens it in Explorer.

Space colour shifts at 80% and 90% full.

Where the data comes from

The local system, polled every 1 to 30 seconds and shared with the other system widgets through one cached sample.

Limits

  • Throughput graphs and the IOPS row are single-drive only. In multi-drive mode you get space bars.
  • Network drives and drives reporting zero total space are not listed.
  • SMART health, temperature and drive model are not surfaced.
