it is a kind of casing in which hdd is inserted & then whole setup replaces optical drive to add 2nd hdd to laptop.you can also just replace your normal hdd by ssd but people need hdd much more than dvd drive so they use caddy.this way small capacity ssd is used for OS & large capacity hdd is used for storage.

It is basically a case which is used for the process of setting the ssd into before installing.
