I know many of the modern external USB 2.5 inch drives do not contain a SATA drive inside, for instance see this YouTube video about disassembling a 2TB Western Digital My Passport drive.
However some drives still contain SATA drives, for instance this YouTube disassembly video of the 1.5TB SeaGate GoFlex drive which contains a 1.5TB SeaGate FreePlay drive that took very long to become available as SATA model.
So: which other (preferably as big as possible, and 12.5mm or less high) SATA drives can be disassembled from retail USB drives?
Edit
The background of my question is that often the official specs will not tell what kind of connector the drive inside the casing it has.
For example some specs for some 1.5TB and 2TB external 2.5inch USB drives in my answer below.
I have two reasons I want to know: often the internal drives are not sold separately at at first and when they are, they are still a lot cheaper. The first reason is most important to me:
I run several dual- and triple-drive machines of which the biggest one is the backup drive that I want to be as big as possible (especially since you now have 1TB SSDs that are 7 or 9mm high).
The OWC 960GB Mercury Electra was the first that was somewhat affordable almost 1TB SSD, but now theM500 and the 840 EVO have taken over.
