History
PC Cards (PCMCIA) were among first
commercial memory card formats (type I cards)
to come out in the 1990s, but are now mainly
used in industrial applications and to connect I/O
devices such as modems . In the 1990s, a
number of memory card formats smaller than
the PC Card arrived, including CompactFlash ,
SmartMedia , and Miniature Card. The desire for
smaller cards for cell-phones, PDAs , and
compact digital cameras drove a trend that left
the previous generation of "compact" cards
looking big. In digital cameras SmartMedia and
CompactFlash had been very common
SmartMedia cards were introduced in 1995 and
were very popular in their day, but they have
fallen into disuse, mostly because their internal
memory architecture could only accommodate a
maximum of 128MB, which is only enough for
around 30 pictures at today’s file sizes.
SmartMedia (SM) cards were also very thin, and
were more prone to damage from bending than
other thicker types of card. They haven’t
been used in new cameras for at least five
years.
