dump/restore 6G USB hard drive takes 7 days

Hi,
I am using a lap top computer with 512M memory a 8 G SSD hard drive. I am dumping and restoring a 6G partition from a 320G external USB 2 hard drive to the internal SSD hard drive partition.
It has taken 2 days to finish 21% and it says finished in 120 hours later. So it takes 7 days to finish a 6G partition dumping/restoring.
The 2 are different size and inode density.
There is only one warning: .snap file already exists.
Some please help me to find the problem.
What I did is:
Code:
cd /usr1
(This is the 6G partition on a 8 G SSD drive)
Code:
dump -L -0 -f- /usr |restore -f-
/usr is the current 300G partition of a 320G USB hard drive, with about 3G files on a partition which is mounted as /usr.
Now it is speeding up. But still it will take a couple of days more at lease.
 
Your laptop is problry an older one. It has USB standard 1.0 and the usbus is rated at 12Mbps. Use command dmesg | grep usbus to verify. Newer PC's use the 2.0 USB standard which have rate of 48Mbps.
