With our HDD / SSD Caddies you may replace the internal optical drive of your laptop for an extra hard drive (HDD) or Solid-state drive (SSD). Our HDD Caddies are made of aluminum and therefore the quality is excellent. To install the drive in the HDD Caddy you'll get a mini screwdriver for free. For a perfect finish you may transfer the optical faceplate / bezel to the HDD Caddy. Now from the outside you can't see, there is a HDD Caddy inside your laptop, but you can take the advantage from extra storage and / or speed! If desired you can still use the internal DVD player. We have external USB optical drive enclosures. There're very useful if you sometimes need a DVD player.
