While upgrading the firmware in my IP cameras yesterday (an annual project here as most of the Wi-Fi cams are mounted outdoors and have to be taken down and brought to the bench), I removed the SD cards from them to use elsewhere. I use FTP with the cameras now and no longer require the internal storage. It occurred to me that in 1985 I bought my first Hard Disk. It was a full sized 5" drive. The machine was a home built Z80 based unit running CP/M (actually by that time I was running ZRDOS/ZCPR) with four 5" floppy drives. There was no built in support for the hard drive, so I had to spend the next month learning how to, and writing drivers for the disk.
The new hard disk stored a whopping 20 MegaBytes of data and cost me $650, plus the cost of the HD controller (I think it was about $300).
These 32 GigaByte Micro SD cards cost about $10 each, and are smaller than my thumbnail.
