    Esto es todo de mometo, en el momento que pueda probar alguna otra SD/MMC.....actualizare contenido....

    ...en cuanto a la velocidad de las tarjetas....parece que la PDA si que "lo nota" !!!

    PD: los datos estan comprobados, son esos, no existe equivocacion alguna,...lo digo por os sorprende los pocos Mb/s que escriben las SD normales y/o MMC Plus....
