Appendix B. Memory Card Formats
The FriendlyNET Gini and Gini II handle the six most popular memory card formats. However, numerous new
standards are being introduced. Here’s a quick summary of the most popular formats are on the market.
CompactFlash (CF)
One of the oldest and most mature memory card formats. It is extremely durable and can handle:
•
Operating shock rating of 2,000 Gs; equivalent to a 10-foot drop
•
100 years with no loss or deterioration of data
•
Integrated controller with dynamic defect management and error correction
Notable products supporting this format include: Canon (PowerShot and EOS Professional digital cameras), Nikon
(CoolPix and digital SLR cameras), HP/Compaq iPAQ Pocket PC (most models) and Dell Axim Pocket PC.
In addition to solid state flash technology, CF cards can handle specialize I/O devices for modems, Ethernet,
wireless 802.11b, Bluetooth and more. Gini does not support these I/O cards.
The standard CF Type 1 card measures 43 x 36 x 3.3mm. The CF Type II card is the same, except that it is
5.0mm (0.19 inches) high. See the
CompactFlash Association website at

Smart Media (SM)
Smart Media cards measure 37 x 45 x 0.76mm and weigh 2 grams. At this time, the largest capacity SM is 128–
