Hello, I have made some test: dd if=/dev/zero of=file.dat bs=1m count=10 SD card on arm - 10485760 bytes transferred in 41.431916 secs (253084 bytes/sec) NFS mount from arm - 10485760 bytes transferred in 6.181458 secs (1696325 bytes/sec) SD card on i386 PC - 10485760 bytes transferred in 6.765610 secs (1549862 bytes/sec) The SD card is very slow on arm may be because it uses 1 bit bus. Is there any problems with 4 bit bus support or my card is incorrectly detected? Best Regards
