The external drive is a Toshiba 5TB Canvio Desktop External Hard Drive P/N hdwc250xk3j1.

According the the specs it is a USB 3.0 drive that is also USB 2.0 compable.

Here is a link to the Toshiba web site.

    Did you see similar performance back when you were running e.g. 6.2.4?
    
    Are you able to try a different filesystem e.g. EXT4?
