Note Submitter: Alex Aulbach ---- Note, that the official IEC-prefix for kilobyte, megabyte and so on are KiB, MiB, TiB and so on. See http://en.wikipedia.org/wiki/Tebibyte At first glance this may sound like "What the hell? Everybody knows, that we mean 1024 not 1000 and the difference is not too big, so what?". But in about 10 years, the size of harddisks (and files on them) reaches the petabyte-limit and then the difference between PB and PiB is magnificent. Better to get used to it now. :) (I added the same note a view days before in http://php.net/manual/en/function.memory-get-usage.php and found it might be also useful here)
