where as a Blu Ray disc is the rest of my Life which is also a Hard Copy
NOTE : I have not burned a Blu-Ray disc... yet.
I will always have a hard copy
that I accessed maybe 10 times in 3 years and that 0ne crashed
They are quiet, cool, emit low levels of vibration, don’t have firmware bugs I would be aware of (unlike the LCC nightmare with the WD green series), and it’s one of the few models in my life where I haven’t seen a single disk failing yet. I’m using about 20 of these for a year. But this is just personal experience and preference, in no way statistically relevant and it’s always best to do your own research.
QuoteI will always have a hard copyI think you might have a wrong expectation about the life time of optical media. I have no hard data on that, but I've seen optical disks turning unreadable in just one year. Statistically, half of all hard drives won't survive six years. But the point is, be it BDs or HDDs, you need multiple copies in multiple locations. You need to monitor the media condition. And you need to be able to restore defects from parity or further copies. And in case of the later you need to know which copy is actually the good one (checksums). Unless you're planning to make this your full time job, doing this with BDs is just not realistic. If you're afraid of HDDs failing, just buy additional ones for more copies of your data. Quotethat I accessed maybe 10 times in 3 years and that 0ne crashedThat may likely be why. As a rule of thumb, each used sector in a consumer grade disk should be read out once per month. Reading out data from a disk is the only way the disk itself can verify its own health and take counter actions (like remapping sectors to spare areas).
but the reduced TLER (Time-Limited Error Recovery: maximum time spend trying to read possibly faulty sectors) is bothering me.
1) Are you using them in single drive (desktop/external drive) or RAID configurations?
2) Have you encountered any unrecoverable errors?
