linux下测试读写速度的简单命令

 

 

# date; cp (MTD NAND directory) filename  (temp directory) filename; sync; date
# date; cp (temp directory) filename; (MTD NAND directory) filename; sync; date

例如:

date;cp /mnt/sda2/music.zip  /tmp;sync;date

date;cp /tmp/music.zip /mnt/sda2/music.zip;date

 

在nuc960测试ntfs读写的结果

 

sh-3.2# date;cp /mnt/sda2/music.zip /tmp;sync;date
Thu Jan  1 00:01:28 UTC 1970
Thu Jan  1 00:01:30 UTC 1970

 

sh-3.2# cd sda2
sh-3.2# ls -l
