He states that they see one drive that is between 94-99%, but that may be a sensor issue. You'd lose the power savings.

Nit: those are not percentages indicating how much helium left, just some undocumented SMART attribute "raw values", there is no direct way to find out their meaning. (This is what the article text implies too).

The raw attribute values could be for example 100 = good 99 = moderate 98 = degraded, or a log scale similar to decibels etc. Or it could be a bitfield that has no meaning as a decimal number. etc
