Isn't optical media a lot less stable than Tape? This seems like a bad idea if you're running an archival service. I use to have a case of CDRs between 1997 and 2004, sometime in 2004 I noticed that many CDRs were becoming unreadable and switched to external HDDs. I kept the case for a while and I think it was 2005 or 2006 that all the disks were empty and I tossed it in the garbage. Around that same time they were starting to phase out LPT ports on PCs and I decided to backup everything I had on reused tapes for an Irwin 40mb Tape drive from 1988 that I acquired sometime in the mid 90s from a salvage shop. I was able to pull everything off the tapes.

Unless you have some giant warehouse of multiple-copying disk-verifying and re-duplicating robots running around.. which in the case of amazon might actually be the case, and at scale, could save lots on media.. to be clear, I have no personal insight as to how their service works

  That seems like a lot more trouble than it's worth. From a cost perspective it makes no sense at all. An LTO-6 tape is $25 retail and holds 2.5TB of data, LTO-7 tapes are $90 for 6TB. A 4 Layer BD-R disk is about $15 retail and holds around 100GB of data.
