Looking for 1.5TB drive 12.5mm high for my caddy or internal bay

Question

w520, have run out of room on my Hgst750. I have a caddy in the optical bay that will hold 12.5mm. Internal bay height the same?
Who makes a 1.5TB this height -- available now?

Thanks for adding the results of your search. For some reason neither item was included in my own Amazon search or the Newegg list I generated.
As a guess both of these might have come out of enclosures purchased by an operation that takes out the drives for resale. ...especially the 2TB unit which when represented on Amazon as a loose drive shows that all the three sellers are not selling me anything ever designed for retail in any form: one says the only warranty is with them, the Amazon reseller. (and that price is $70 higher -- for the privilege?) I had been reading about the practice and its downside.
I am hoping to avoid this; perhaps a few more months, a year, will find the same slim units on the more open market and guaranteed by their respective manufacturers. For now I will pass, then, and do some more aggressive culling of content off into off-line cloud storage.
Again thanks for the further search results.
