Consumers can expand the functionality of their computers and laptops by installing Blu-ray drives. This upgrade allows your computer to read discs that use a 405 nm "blue" laser diode, the technology that allows for much more storage than DVDs and CDs. Many model support up to 128 GB recordable Blu-ray dics. These drives use a Serial ATA interface that allows your computer to read the data on discs quicker because of higher signalling rates and I/O queuing protocols.
Those who do not want to deal with installation can opt for an external Blu-ray drive. Simply connect one to your computer or laptop via a USB cable. If you prefer an internal device, computers and laptops limited on space may require a slim device installed.
