I use the card in my 300 GPS Yakumo Pocket PC and many years am very happy with the choice of this card. I have tested the card on the PC with the HD Tune program and this is my result: Maximum transfer rate: 6.9 MB / sec Maximum transfer rate: 9.1 MB / sec Average transfer rate: 8.8 MB / sec Access Time: 10.6ms Burst rate: 5.6 MB / sec CPU Usage: 16.9% (Results may vary depending on the card and the hardware used)
Overall, a highly recommended map with very good speed!
