CDs, DVDs and Blu-ray discs, have been around for years, with CD being the first to arrive on our High Streets way back in the early 80s. At the time CDs were incredible versatile, fast and convenient compared to old audio compact cassette tapes that were its predecessor.
CDs could store anything up to 700MBs worth of music, which at the time was a considerable amount of storage.
DVD arrived in the 90s, offering over 4GBs of storage for music, films, photos etc.
Blu-ray, came along in the early 2000s, blitzing the storage space of DVDs with 25GB for single-layer, and twice that for dual-layer. The big advantage with Blu-ray over DVD and CD was most evident in resolution quality in films - a bit like watching a standard TV broadcast compared to HD or Ultra HD.
However, all three formats have more or less come to the end of their days. DVD and Blu-ray still have their uses, especially for computer games. But these days USB flash-drives are far more versatile, and can hold considerable more data (anything up to 2TB!)
