SATA 9.5mm HDD Caddy

A SATA 9.5mm HDD caddy is a device designed to house a 2.5-inch SATA hard drive (HDD) or solid-state drive (SSD) within a 9.5mm enclosure. These caddies are commonly used to convert optical drive bays in laptops into extra storage spaces by allowing you to install a secondary hard drive or SSD.
