if the sector sizes of the drives are different, i.e. 512b/4k is that an issue?

This device is pretty much like connecting hard drives inside the computer case. I don't think it will be a problem. I've had very good luck with these units but I'm not using different drives with different settings.

If the "clone" rate is 1tb / 4hours, then a 4tb drive could take as much as 16 hours to clone?

Dear customer, Welcome for your question. Yes,it will take 16 hours to clone. ORICO customer service team

If one were copying files to/from both drives simultaneously (to ones primary internal drive) would the transfer rate be slower?

Yes some slow down if going from both at same tim but it take bout same amount to both ways

So this definitely won't support 2x 14tb hdds? is there a version of this product that does?

Look into getting a NAS, from QNAP or Synology. You'll thank me for this advice later.
