tt is the output filename , current dir is /media/新加卷（the mount point of the sata disk,NTFS type ）I also do a similar test via samba, the speed of copying a 256M file from BPI to win7 is about 11MB/s, bottleneck seem to be the 100Mb/s network; however the speed of copying a 256M file from win7 to BPI is about 4.1MB/s; posible bottlenecks are BPI's filesystem（ntfs-3g）, BPI's samba server,or the board itself。
hdparm test gives a satisfactory result:
root@lemaker:/media# hdparm -tT /dev/sda
Timing cached reads: 540 MB in 2.00 seconds = 270.09 MB/sec
Timing buffered disk reads: 202 MB in 3.02 seconds = 66.89 MB/sec
so,what's the problem? thanks!
