The greatest havoc is caused by Hard Disk Failure. You loose 1 to 4 TB of Photos at the click of your thumb. But you loose only a few GBs on a failed DVD. Generally CDs from the 80s & 90s & recent DVDs + Blu Ray Discs should play fine assuming you have not scratched them.
So here comes the 1000 year M-Disc - archival disks - literally in destructible. How?? Normal CDs & DVDs have Organic Dyes in them that fade or destruct making them unreadable in Disc Players over time. You get M-Discs in capacities upto a 100 GB and the prices are falling. The data layer on M-Discs are indestructible highly polished rock pieces. I bought a 4K Toshiba Laptop in Toronto 3-years ago with a Blu Ray Recordable Drive. Using the Free ImgBurn Software I can burn the M-Disc - pretty fast & sweet - no failures so far. I bought a pack of 5 x 25 GB Verbatim M-Discs a year ago for US $ 17.71 with Free Shipping. As to that thousand-year claim, the U.S. Navy will back that up. It tested M-Disc DVD+Rs along with archival quality DVD+R/RW and DVD-R/RW, subjecting them three times to a 185 degree, 85-percent humidity, full-spectrum light environment for 26.25 hours. Every DVD failed—except the M-Discs, which suffered no noticeable degradation. https://en.wikipedia.org/wiki/M-DISC http://www.mdisc.com/ http://www.pcworld.com/article/2933478/storage/m-disc-optical-media-reviewed-your-data-good-for-a-thousand-years.html Suggest please try them. Just Google which Blu Ray Recorder can burn M-Discs. You even get portable USB Blu Ray Burners for under US $ 40. Regards.
