Memory Cards

Portable media has put pictures, videos, movies, and other files on the move in the 21st century. After the SD card was unleashed, one fact became clear: although it was a marvelous advent, it was still too large for portable electronics. And so the 16gb memory card format was made suitable to supplement various devices' built-in memory. For instance, some MP3 players may come with an expandable memory slot, upgrading it from 512MB to 2GB. In terms of its size, a miniSD memory card has a clear advantage, because it's nearly half the size of SD cards. Measuring just 20x21.5x1.4mm, it was designed elegantly, for use in medium-sized handheld devices like voice recorders, cameras and video recorders.

When the SD Association established the miniSD brand in 2003, little could be predicted about its success. There was a demand for smaller memory chips, but would miniSD win? Because the SD Association had previous experience in such non-volatile flash media formats, launching it wasn't a problem; the Association already had connections with large companies that manufactured various SD-compatible electronics, which quickly adapted to miniSD memory cards. The main advantage of miniSD over SD was its size, and it even lacked a write protect switch, but technologically they were nearly identical; fears of redundancy made room for doubt in its success. The result? Today, a tiny, 32GB miniSD memory card can fit over 545 hours of 128Kbps music on it.
