Age old question – How much remaining “Free Space” should one leave on a drive. We have all asked the question and have found numinous answers. For myself, my “System drive”, I prefer to have at 50 percent, at times allowed to get to 30 percent .. many suggest 20 percent is the magic number. Additionally keep a current “Image Backup” of this drive (biweekly), plus dynamic info (email, DOC, ect) 3 times daily (on drive 2- Data Internal Drive). I will leave that discussion for another time.
My question is my 3rd drive, a 2TB (formatted to 1.81TB – Movie Data only), which is 12.8 percent remaining space. .. but that value is 232GB. It has a large collection of family movies and DVD’s stored on it. Now 232GB is a lot of free space, but 12.8 percent “Remaining Space” is a small number. What suggestions / technical reviews / experiences have you folks had in managing this question. How low can “Free Space” go and SAFELY maintain this data on today’s very large drives??
