Small, yet perfectly formed opinion; the Tableau TD3 is pretty fast at cloning drives. I'm doing a 500GB HDD this morning and it's going to take 3 hours total to clone & verify to another 500GB drive.
(This is a "best case" situation where both drives are connected directly to the TD3, however)
Yep <img src="images/smiles/icon_smile.gif" alt="Smile" title="Smile" /> , but the OP was asking about disk images, not clones, and of huge 2 or 3 Tb disks.
I wonder how fast (slower) it can be when the target is on the network (see below).
And those data don't strike me as "blazing fast".

I may be particularly pessimist <img src="images/smiles/icon_eek.gif" alt="Shocked" title="Shocked" /> , but a 3 Tb drive in 7h 20 seems to me (I know you highlighted that this is a theoretical speed) very far from what you get in practice.
The data Chris_Ed just posted would lead (if linear/proportionate) to a nice, round, 3hx3000/500=18 h time for a 3Tb disk through a Tableau (with direct connection which is surely faster than network). <img src="images/smiles/icon_confused.gif" alt="Confused" title="Confused" />
And, the "area" of interest of Zul22 is data recovery, so possibly the write blocking of the Tableau (or other similar write blocking device) is not-so-relevant, while it is to be expected commonly that the source is non-fully-functional/has-issues-of-some-kind.

Have a look at this thread also:

which revolves around topics very close to your question, particularly here:

a link is given to the results of a nice set of test data:
