I belive that 2 MB/s should be achievable with the optimized MFS and drivers.</P><P>Regards, Pavel</P><P>&nbsp;</P><P>&nbsp;</P></BODY></HTML> Tue, 26 Jun 2012 18:45:55 GMT https://community.nxp.com/t5/MQX-Software-Solutions/MFS-SDHC-Class-4-on-K70-Tower-Throughput/m-p/174724#M2220 pavel_chromy 2012-06-26T18:45:55Z
