The Gigabyte has become the new Megabyte

Just when you think you’ve finally gotten your head around the fact that you can fit 16GB of data on a memory card no bigger than your fingernail (MicroSD), along comes the next-generation of memory cards, SDXC, which proclaim a whopping 2TB on the same form factor!

The website referenced above suggests that a 2 TB SDXC memory card could store around 480 hours of HD recordings, or 136,000 photos. However, looking backwards to previous technologies and storage terms, 2 Terabytes is the equivalent of two thousand Gigabytes, or 2 million Megabytes, and would be roughly equivalent to 1,388,888 floppy discs (of the 3.5″ high density variety from the nineties which had a capacity of 1.44MB).

Oh the times they are a’ changing…
