How to get total disk read/write in bytes per hdd device?

for example if i have sda, sdb, and sdc, is there any file on /proc that i could use similar to /proc/net/dev for networking?

You can use this command to see disk Read and Write for specific time. like for 1min use:

# dstat -tdD total 60

Value after total is in seconds.
