That's a typical mSATA/m.2 external enclosure- they have solid state drives so no moving parts and no sounds. I've bought a number of these cases to hold mSATA/m.2 drives I've pulled when upgrading them, to use as external drives. This one shows what they look like and the types of mSATA drives that will fit. (I haven't used this one in particular, just an example)

They're quiet, but do get very hot when you're using them.

The link has been cut off so we can't see the product listing. Vollpfosten mentions 2TB drives are pretty expensive and has good advice if you paid less than he mentions.
