There's very few out there that are UHD compatible.

Here's two that are official UHD drives:

LG BU40N

LG BU50N

Alternatively, you could buy an external USB3 model and just take it out when needed. Although I think this one would only be good for ripping/decrypting since it's not an 'official' UHD drive.

LG BE16NU50

You could also get an external enclosure like the one below and pair it with any of the confirmed UHD compatible 5.25" ODDs.Vantec NST-536S3-BK NexStar DX USB 3.0 External Enclosure

I was on the hunt recently for a slot-loading UHD compatible drive instead and that seems to be non-existent :(

Formfactor is a given...
What you are describing is a typical slimline ODD. (And that's what the Envy uses.)

So, given the formfactor assumption... any ODD (That fits) will work.
