On linux, one can follow the advise of the majority of the hits which suggest using dd to clone a disk, but it seems that adding a blocksize to the dd is very useful.
I looked at the stream being read w/o a parameter, and found that it was at bs=512, which is the default. After about 3 hours of copying the dd had copied 331gb.
I restarted with a bs=20480000 or about 20mb and in 20 minutes the copy is up to 120gb copied, or somewhat over 5 percent, suggesting that it will copy complety in 200min or about 3 hours total.
