CD - you can read the thing after it gathered dust for 10 years. Personal experience for both CD-R and CD-RW. An amount of information can be stored is unreasonable by today's standards. DVD - you can read the thing after it gathered dust for 5 years. Personal experience for both DVD-R and DVD-RW. An amount of information can be stored is unreasonable by today's standards. BD - no personal experience with those. USB drives - ok, but will require periodic poweron/poweroff cycle. MTBF is less as of the modern HDD, which is not much again. So, for a long-term storage one is basically left with the same thing as 20 years ago, i.e. - tapes. LTO5s go for $10 each on eBay, providing you with 1.5Tb per tape. A cost of LTO drive is painful somewhat ($1500 ), require an additional SAS or SCSI controller, but this is one-time investment basically.
