usable capacity

back in the day, it was std. parctice to only use upto 80% of the total HDD capacity in order to get maximum performance. HDD have improved a lot and i was wondering if this is still a good rule of thumb to follow still. Does this also apply in a RAID configuration since it already reserves space for the 'overhead'.

  1. back in the day that was the practice cause if you didnt you could easily run out of hard drive space if your computer expanded your swap file. its not really neccissary anymore, just leave about 500 megs free on a system drive. on a drive you just use for storage it doesnt matter, except for that stupid you are low on space message.

    this is my boomstick!
  2. thanks for your response ... it clarifies a thing or two.
