This work serves as a proof of concept, showcasing my vision of the most informative way to present disk information.

Details

The idea is simple — divide the occupied/free space bar into blocks of a fixed byte size (e.g., 100 GB). This way, both used and remaining space are immediately clear at a glance. Unlike my approach, the "classic" solid bar representation provides no absolute information about how much space is used or free; it only shows a relative percentage, which is of little practical use.

Solid bar (classical widespread solution)

• Total drive space can be known only by looking on the numbers
• Remaining space shown in percent from total drive space, it's not easy to estimate absolute remaining/occupied space (how much GB left)

Bar with fixed byte size blocks (my proposed solution)

• Total drive space can be easily visually estimated (only if it's larger than block size).

• Remaining space still shown in percent¹ and it's easy to estimate absolute remaining/occupied space (how much GB left) visually.

  ¹ A bit inaccurate, becouse I didn't deal with spacings in partial block fill calculations, but it's not the idea's problem
