Definitely vibration. Of the two in question, one is a western digital "elements" 2 terabyte drive and it's laying down flat.
The other is the older "Mybook" 2 terabyte drive and it was standing up like a book on top. So there was not enough surface touching to carry any heat. Plus there are little feet on them to allow air between and they are barely lukewarm to the touch.
Since the mybook is older I expected the write speed to be a bit slower, I am not even sure it's SATA inside there, could be an ATA drive, but even back in the day when ATA was standard I got better than 12MB/s off of my external drives with USB2, so I know something was up.
I put my hand on it and felt a lot of vibration and thought "what if that's affecting the read/write head?" It appears that it was.
