The data transfer is based on the SATA and PATA electronic interface but the physical connector is different. For instance some laptop manufactures have designed their own physical optical drive interface based on the SATA and PATA technique. However the physical interface from different laptop models can differ. These SATA transfer speeds are also known as SATA1 (1.5 Gigabit), SATA2 (3.0 Gigabit) and SATA3 (6 Gigabit). The SATA connection can achieve much higher transfer speeds namely 150MB/s, 300MB/s and 600 MB/s. The PATA (IDE) connection is limited to 33, 66, 100 en 133 MB/s. The PATA connection is the predecessor of SATA and its theoretical transfer speed is much lower. Basically most optical drives uses the SATA or PATA (IDE) technique. Dvd connector interfacesĪ second issue is the interface incompatibility of the optical drive. – The mounting brackets are part of the optical drive and cannot be removedįor some laptop models a HDD Caddy requires some physical modification. – The ejector is part of the optical drive and cannot be removed Universal HDD Caddy uses a standard fit for the assembly of the bezel. – The bezel of the optical drive has a different design than the standard. – For instance the bezel of the optical drive cannot be removed

Which means these drives do not fit in other laptops and are tailored to a specific laptop or laptop series. However a part of the existing laptop models are using proprietary optical drives. Physically these sizes fitted in most laptop models. If your laptop model isn’t listed please send us an email ( and we will appoint you with the correct HDD Caddy.Īvailable sizes (of thickness) of caddies are 7mm, 9.5mm and 12.7mm. If you are looking for the correct HDD Caddy for your laptop please use this list. Or check the right side of this page you’ll see a list of laptop manufacturers. With HDD Caddy you do not need to carry external hard drives or USB sticks anymore. But thanks to HDD Caddy we can add this option by replacing the optical drive (DVD drive or BluRay drive) with a second hard drive or SSD. Unfortunately this option is in most cases not available for normal sized and smaller laptops. This option allows you to have two hard drives in one laptop. Large 17 inch laptops have the so-called dual hard drive option.
