Any program to test the read/write speed of disk drives and USB?
 

I would like to know the way I can test the read/write speed of my hard drive and USB..

thanks in advance

Hi, you can test ur disk speed by
sudo hdparm -t /dev/sda

where ,
/dev/sda is ur hard disk similarly u can give ur usb drive name, (It looks like sdb or sdc etc)

simplest mechanism is to divide the filesize with the time taken to copy/write.

You can also use ethereal for more granularity of data.
