Memory Stick PRO-HG is expected to take digital storage to the next level by adding increased performance and large capacities (up to 32GB). Performance has been increased by upping the internal core clock from 40MHz to 60MHz. As a result, the maximum data rate has jumped to 60MB/sec -- three times that of the Memory Stick PRO format. Minimum write speed for Memory Stick PRO-HG media is listed at 15MB/sec.
While still nowhere near as fast as a desktop hard drive, the read speed and capacity of these cards is amazing, making the larger ones very suitable to place into many things beyond portable devices. A laptop with no shock-vulnerable hard drive or a media machine that is truly completely silent would be possible. This is definitely an area in which Sony could make up for the disaster that was 2006 for them, by tackling specifically the two biggest issues people have with flash: Speed and capacity. Supposedly, the first cards will start to appear next year, though not specific release dates are available.
