To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
When formatting disc for 1st time , total GB is 93.2 which then reduces to 90 once formatted. I wish these Total GB's were accurate on every formatable device. Still able to fit a lot of HD and 4K video files per disc and you have to be happy with the lifespan which these discs offer. One star deducted for not being 100GB.
