Unfortunately I have bought the card, since the price was really good, but after the first write to the card, I noticed she writes very slowly on the map, I have other Transcend 4GB (120x) cards that are much in write faster, just like my ScanDisk 2 or 4 GB Extreme III cards. Reading is for the super card because my other cards do not come with any. Who it again write to the card arrives, you should rather buy another card. If it does not matter and the reading of the card is more important, can only recommend the card for the price. Here again are data to the map:
