techPowerUp posted a review on the A-DATA Super Info SD Card 512MB

The A-DATA Super Info SD card comes with a little LCD readout that can display volume name and remaining capacity. This is a very useful feature because it allows you to check what is on the card without inserting it into a computer. The performance of the card is good as well, transfer rates are in the 12 MB/s range with access speeds of only 1.3 ms.
