I have left about 10% (47GB) of space unused/free on Samsung SSD 840 Evo 500GB. Is it reasonably or can I use this SSD to almost it full capacity, let's say 10GB free? I ask because I heard that one should not use total capacity of SSD, to keep it in good condition. Is it true with recent SSDs? However now I run out of space on SSD (system/programs/games). My SSD is MZ-7TE500BW (Samsung 840 Evo 500GB not PRO)
