>>51087686Not him, but regardless, blu-ray is a good backup method. It's got great storage density, writers are relatively affordable, and you can read the UDF filesystem on just about any platform in existence.
They last a long time too. Conventional DVD-Rs and CD-Rs are only considered good up to a decade or so, but that's because the dye used for recording is sensitive to light. If you keep them in darkness, they should last a long time.
Blu-ray disks are even better w.r.t. lifespan:
> The recordable media used in red laser disc technology like DVD's and CD's is an organic dye that is very sensitive to light. Blu-ray disks, however, use a combination of silicon and copper which is bonded during the burning process, this alloy is much more resilient than the organic dye. Manufacturers claim a life span from 100 up to 150 years for Blu-ray disks.Tape readers/writers are not cheap or plentifully available. Blu-ray is a great commodity backup methods.
Get real, your requirements are not the same as Amazon, and you aren't dealing with petabytes upon petabytes of data.
>>51087708> In this scenario just get a HDD that's known to be rather reliable.If I weren't using physical written media, I'd probably be using SSDs, not HDDs. They're much less prone to random failure because no mechanical parts. Their death is mostly predictable and they should remain stable almost indefinitely as long as you don't keep writing to them.
With HDDs, when you go back to read your data, you might find it's no longer accessible. Especially if the mechanics were exposed to seasonal temperature changes for a long time without use.
