Owners of Sony and Sony Ericsson digital devices will be delighted to hear that the Memory Stick PRO Duo has undergone a large storage bump up to 4GB, nicely
doubling the previous flagship of 2GB. Surprisingly, this news comes not from Sony, but from memory guru SanDisk. A high-speed data transfer rate of 15MB per second helps prevent data loss and supports DVD-quality video in real-time. This new memory tick also features advanced security with Access Control Function and MagicGate technology. Best of all, SanDisk gives you a little card with a lot of freedom at a very reasonable price.
