I think that it's more likely to be the interface. The drive is a Seagate
ST31000523AS, which has a SATA speed of 6 GB/s, a Transfer Speed of 600 MB/s
and a Sustained Data Rate of 125 MB/s. Clearly the Data Rate would be the
limiting factor if I was connecting the drive directly to a SATA interface so
it would theoretically give a total time of 2.22 hours to complete the
process.
However, there is a USB interface in the way and I think that is slowing the
process down by a factor of 4 to 5.
