SD cards are small and can fit inside certain cell phones.
Digital camera memory is an important feature of digital photography because it essentially is the digital equivalent of film. Digital cameras can have internal memory, an external memory card or a combination of both. There are several different types of memory cards with various storage capacities, sizes and features.
CompactFlash
This is one of the most common types of digital memory cards. Most compact cameras and all D-SLR cameras are CompactFlash compatible. They usually are inexpensive and feature an internal drive device that allows for faster processing. They come in two sizes, Type I and Type II. Type I is slightly thicker, while Type II has slightly larger storage capacity.
SD and MMC
Secure Digital, or SD, and MultiMedia Cards, or MMC, are memory cards and the smallest available on the market, They can be used with some phones, PDAs and MP3 players. Their maximum storage capacity is 512 MB. The only difference between the two is that SD cards have a security switch that prevents them from being overwritten.
xD Picture Cards
Introduced by Olympus and Fuji, xD Picture Cards are small memory devices with a storage capacity of 512 MB. They fit into many smaller cameras and are compatible with devices that accept CompactFlash cards.
Memory Stick
Memory Stick is a Sony product developed for its CyberShot line and certain other company products. They are not compatible with other brands. They are available in 256 MB and 1 GB capacities.
MicroDrive
MicroDrive is a miniature hard drive encased in a Type II CompactFlash memory card shell. It was developed by IBM and was the first memory card to hold a full gigabyte of memory. However, because they contain moving parts, they are fragile.
SmartMedia
SmartMedia cards were the predecessor to xD Picture Cards. They were used in most Olympus and Fuji cameras but are being phased out. Because of this, their price has dropped significantly, making them an inexpensive option.
