It appears clonezilla is using dd and the speed is extremely
slow (~5MB/sec) and it says it's gonna take 1 day to clone the 500GB.
BTW, is it normal for dd to be this slow, or is there something wrong
with my setup?  These are quite modern drives and should be able to
handle sequential transfer of 10's of MB/s.  I have never used dd
before so I don't have any experience.
dd should be pretty close to the max possible throughput of yer drive.
 For example, I dd'd a 1T WD black not too long ago & it was around
120MB/s on the outside & 70MB/s in the middle.
