anotherpaul - I have the same model number and same EXACT drive as you…this is the product page of my drive on my Amazon orders list → http://www.amazon.com/dp/B00E3RH61W
The model number you see in linux is the actual model of the drive inside the enclosure…which is their green 4TB drive. But the product model number (ie. of the enclosure with the drive) is WDBFJK0040HBK - same as yours. And the latest SAT Rev shows SATA Rev. 3.0…the info you gave is identical to mine (except of course the serial number which we both only disclosed partially here). There is NO difference between the one sold in blue box and the one in green box.
