Blu-ray / DVD Drives were once widely used for storing and archiving data in home or small office environments. Most desktop PCs and laptops came with internal drives that supported optical media. Internal Blu-ray / DVD Drives for desktop PCs connect via the SATA bus and fit into a 5.25-inch drive bay, supporting both DVD and CD formats. A single-layer DVD can store up to 4.7GB.

Internal Blu-ray drives also connect via SATA and use a 5.25-inch drive bay. These drives support DVD and CD formats, with a maximum capacity of 25GB for single-layer Blu-ray discs and 50GB for dual-layer Blu-ray discs.
