Now the M-DISC comes in a 25GB Blu-ray! With all of the longevity benefits of our original DVD, the Blu-ray gives you over five times the storage capacity on one disc. As technology rapidly advances, we're living longer, doing more, creating more memories and recording more data. Every scrapbooker, business owner, photographer, every person fears losing the legacy they have spent their lifetime creating. M-DISC eliminates that fear. Once written, your documents, medical records, photos, videos and data will last up to 1,000 years. "Just M-Disc and Forget It!" M-DISC archival media is the perfect solution for any size business or even individuals looking for long-term storage of important digital files. The M-DISC is the first ever permanent file backup disc that lasts forever. Unlike computer hard-drives and optical discs (CD, BD and DVD) that suffer from decay, destroying the files you were trying to preserve and protect, the M-DISC cannot be overwritten, erased, or corrupted by natural processes. Best of all, you can access your data anywhere and anytime. It is the new standard in digital storage. Keeping back-ups on optical media is becoming more and more important as it's the only true incorruptible and safest method of storage. Optical discs are the only medium that cannot be altered or infected with viruses after data have been stored on them. Flash media (like USB or SD) or hard drives, even with encryption software, can be altered, or infected with viruses or spyware that can compromise the information stored. Also, and even worse for the casual consumer, the data stored can be erased, leaving potentially critical files or priceless mementoes, like pictures, gone forever.
