I have tested the card on the PC with the HD Tune program and this is my result:
Maximum transfer rate: 0.9 MB / sec
Maximum transfer rate: 0.9 MB / sec
Average transfer rate: 0.9 MB / sec
Access Time: 6 ms
Burst rate: 0.8 MB / sec
CPU Usage: 3.3%
(Results may vary depending on the course map and hardware used)
Compared with my 512MB Sandisk card (average transfer rate 8.8 MB / sec) This is a ernütchterndes result.
