Product introduction:   This universal OptiBay replacement optical drive second hard drive bay is a newly developed product. The material is mainly made of thickened pure aluminum alloy. With other processing, the bracket is stronger and can prevent scratches very well, and the quality and function are very good. It is the same size and socket as a standard optical drive with the same thickness.  Product parameters: 1. Product model: All-aluminum thickened version 2. Applicable models: (for reference only) All optical drives are 9.5mm, 12.7mm thick SATA interface laptops, all-in-one computers, servers, etc. 3. Connect to laptop interface: SATA 4. Supported hard drives: 2.5 HDD, SATA I II III, SDD (solid state drive), 7mm/9mm thickness, the new solution adopts SATA3.0 technology, the speed can reach 6Gbps, the specific operation depends on the optical drive position on the motherboard of your machine Channel standard decision. 5. Product material: aviation aluminum 6. Product size: 129mm*128mm*9.5mm. 7. Product weight: 0.115kg 8. Hard disk capacity: unlimited capacity (tested 1TB)   Product selling point: 1. Aviation-grade magnesium-aluminum alloy material, with anti-static black film, and double-layer oil transfer technology at the bottom to better protect the hard disk bracket from scratches. 2. The 2018 new and improved version, the aluminum skin is thickened, which not only ensures the sturdiness of the hard disk bracket, but also does not lose the standard 9.5mm thickness, and the screws also have a new practical patent design to ensure the safety of the hard disk. 3. Shell: aviation-grade magnesium-aluminum alloy, standard 15-degree hard drive material. The surface is anodized and plated with a double-layer process of transparent insulating film. There are 9 positioning holes on the three sides for precise tapping, which replaces the optical drive and is easy to install. 4. The new original Taiwan imported adapter, the defective rate does not exceed one thousandth 5. Inner frame: brand new PC+ABS material 6. Hard disk fixing method: four-side locking screws, 3D precise positioning of the hard disk. It is fixed with four magnesium-aluminum alloy screws to reduce more troublesome installation steps.
