The Memory Stick digital storage device is designed to become a standard storage and transfer media. It's smaller than a stick of chewing gum, yet PQI's smallest MB (64MB) has a minimum of forty times the storage capacity of a standard 3.5-inch floppy! Due to its compact design, it is best suited for use in small digital electronics products. Many Sony products use the Memory Stick as a standard in their digital line of products. Coupled with a PQI USB Reader, this device can read those important pictures, retain that movie soundtrack or store that valued document.
