For cheaply storing data, sure. The dye on burnable discs tends to degrade over time, though, making them poor for archival purposes.

- dragontamer 5y agoEverything degrades over time. An archival quality DVD has dyes that resists the bitrot. Archival quality magnetic mediums (HDDs or Tape, or floppies) also resist the bitrot... but they're not immune. The only way to fully avoid bitrot is to constantly read-and-rewrite the data. You need to read the data before it degrades: that could be once a year, or maybe every few months. But cold-storage is just a devilishly hard problem. Its probably best to just not deal with that at all. Just get a NAS and read/rewrite the data automatically (aka: "scrub" your data in ZFS terms)
