A new, weird and unnecessary unit of data capacity, created by some idiots of IEC and aggressively advertised on Wikipedia. 1 Mebibyte equals 0.9765625 Megabytes and serves no purpose other than confusing people and as an excuse for ripping customers for a few extra bucks.
The big red letters on the box say "512 MB", but those are our brand new Mebibytes! In fact, your flash drive can only store up to 488 old, bad and stinky Megabytes.
