* - Memory Stick PRO media supports parallel transfer to enable simultaneous transmission/reception of multiple data. In the parallel mode, data is transferred at speeds up to 160Mbps (theoretical value), making it possible to record DVD-quality moving images in real time (when Memory Stick PRO media is used in a product that supports parallel transfer). To meet the requirement of high-quality video recording, the minimum write speed has been standardized at 15Mbps. When used with an optimized Memory Stick PRO-compatible product, Memory Stick PRO media can write at speeds of 15Mbps or higher -- fast enough to record DVD-quality video, which is recorded at 9Mbps. Even if power is interrupted during recording due to battery depletion, etc., data recorded up to that moment is not lost. With this media, users can efficiently and smoothly record massive volumes of data.
** - Designed specially for use in ultra-compact and wearable devices for mobile applications, these media are one-third the volume of standard-size Memory Stick media. Yet they deliver the same performance and functions. By attaching an adapter, they can also be used in a versatile line of products compatible with the standard-size media.
*** - Transfer rates of up to 20 megabytes per second. Ultra-compact for smaller devices (MS PRO Duo cards are roughly half the size of MS PRO and are intended for use in smaller-sized digital devices). Memory Stick PRO Duo packs all the advanced functions of the Memory Stick PRO media into the compact Duo format. This was made possible by adopting higher-density multi-stack technology.
