The ADATA Super Info SD series card definitely brings some nice new features to the SD-card market. One of the great things about this card besides from the excellent performance is the display that can display two characters of your choice and the remaining capacity on the card. Because you can assign two characters it's easy to label your card and you won't have to insert the card in order to get an idea of what's on it.
When it comes to performance the ADATA Super info SD series cards won't let you down. The read speed is really high and so is the write speed although not on pair with the OCZ Secure Digital Dual's write speed. The benchmark in which the ADATA card is unrivaled is access time. At only 1.3ms random access time this card is the most responsive of all the cards that I have tested and had. Because the latency is so low this card could be the perfect buy for some one wanting to speed up Vista boot times, the fact that it's so small makes it a reasonable upgrade for a Vista laptop, because you can keep it inserted in the laptop at all times.
Overall I like the idea of the Super Info SD cards, the display is a welcome addition to a SD card making it easy to label your data and keep track of remaining memory. The downside of the display is the added cost of the card, but I really think that it's worth the added price.
