• Write Speed - 32Mbps When combined with optimized Memory Stick PRO format-compatible devices

1GB memory capacity * supports read and write speeds of up to 32 Mbps * designed to operate with high-def AVCHD recording devices * some memory required for system management * SDMI-compliant MagicGate encryption technology *

The price on the 16GB card continues to tumble (even in the time between placing and receiving my order). I bought a couple of these to play movies and music on my PSP.

I found no compatibility problems with either the PSP or the old card reader on my desktop or the reader on my laptop (though the laptop is a Sony). The description does not mention it, but my card came with an adapter so it can be used in a standard memory stick slot.

It was worth the premium to go to a larger size to cut down on card swapping. In fact my only complaint is that 16GB is not enough. Looking forward to the 32GB cards.

READ BEFORE YOU ACT!!! BEWARE OF FAKE CARDS!!!
I bought this Sony MSMT16G 16GB Memory Stick PRO Duo (Mark2) Media Card from one of Amazon "Featured Merchant". It came with a very original look like packaging, even a hologram on top. As soon as I insert it in to my video camera it did not recognized. I tried another same type camera and also a media card reader with no luck at all. Then I found lots of information on the net saying there are fake ones which won't work with cameras and else. So be careful don't buy a fake one, like me.
