The PhotoFast CR-5400 is an adapter that converts two microSD/microSDHC cards into one Memory Stick Pro Duo, giving up to 32GB (2x16GB). The cards can have different capacities, and the transfer speed is 10MB/s and up.
The adapter uses original controller chips and is fully compatible with Sony devices, PSP and cameras. It supports Class 6 and 150X devices and preserves the original speed of the inserted microSD cards. When two different card types are used, the slower card sets the speed.
If only one card is used, it must be placed in slot 1. New cards must be formatted with a Sony product before data can be stored. For copying or deleting, the whole adapter should be inserted in the card reader, as writing directly to a single card corrupts data. The package contains one microSD to Memory Stick adapter (CR-5400).
