Reverse Engineering

...or testing to destruction?

Ever wondered what lies inside one of these marvels of electronics? As the READ-ONLY tag had fallen out of this card, it was pretty much useless for transferring files, as they could not be deleted, once added. So I broke it open.

It is, of course, not a SD card itself, so it contains no microchip. It serves as a container, allowing Micro-SD cards to be mated with SD Card sockets.

I still sometimes have to sit back and reflect on the growth in storage capacity available on these devices lately. 32-64 GIGA Bytes of data are not uncommon. When I started as a software engineer in 1980 we worked on a DEC PDP-11/34 with a massive 128 KILO Bytes of memory and - wait for it - 20 MEGA Bytes of storage (on four removable disk platters the size of family pizza dishes).

Incredible...
