Memory Storage Formats
Memory basics explained
There are several memory formats used for storing music. They are incompatible, so making a purchasing decision now will pave the way for what you use for many years to come. Finishing this series will help you to become informed and make an educated decision for happy results long into the future.
Step 1: What is digital memory?
Memory cards are small, removable storage units that are used in portable MP3 players, digital cameras, and small palm-sized PDAs (Personal Data Assistants).
Step 2: How much data can they hold?
The memory cards can hold anywhere from 16 to 128 Megabytes of data. 128 megabytes can hold 4 hours of average quality music (remember - the higher the bit rate, the higher the quality, but the size is larger too.
Step 3: Are they always portable?
They can be taken out and swapped just like cassette tapes. In fact, some portable players force you to take the memory card out to change the music located on the card. Be aware that some have memory "on the board" which means that memory cannot be removed, but can be written over thousands of times.
Step 4: What about volatile memory?
All memory in this category uses Flash RAM technology that is non-volatile. This means that the data will remain on the card even if the power is turned off. Most memory on your computer is volatile and is cleared when the power is turned off.
