Supports 2 MicroSD/MicroSDHC TF cards even different capacity can be used.
Different MicroSD Cards can be used at the same time (for example 2GB+16GB). You have the freedom of expansion and upgrade. The adapter works with only one MicroSD card as well. The second slot can be equipped anytime later. You can exchange the cards and upgrade to the maximum capacity of 32GB. The slowest MicroSD card used sets the speed rate. If only 1 MicroSD(HC) cards is used, it must be inserted into slot#1 in order to work.
Do not use the card reader copy or delete data from the TF Card / MicroSD/ MicroSDHC. In order to copy or delete data directly, insert in your card reader.
Don't take out the MicroSD(HC) cards and perform write operations on the single card. Your data will be corrupt.
When using new MicroSD(HC) cards, you need to format with a SONY product before you can store data such as psp.
