My BD-R story:
For a little bit I was trying to go Blue Ray for backup of conference
talks I was recording at the time. I picked up a Samsung BD-R drive and
some memorex media. The media for BD-R comes in a High to low and low to
high versions. One is dye based not for long term, the other type is long
term. The Memorex type I got was the long term type.
I carefully made 2 or 3 copies of each set of video files. Each event took
2 to 3 discs (Was recording events live using Blackmagic ATEM system, 5GB
per hour is the data rate in 1080i60 h264 encoded.)
After about 9 months I went to copy some data back. It was all gone.
Everything deteriorated and all the data was unreadable. Before I bought
the drive I looked for info on reliability and didn't find any indicators
that the media sometimes has severe issues.
Since then I kind of swore off optical media. I have some Verbatim discs
but I haven't used them yet. I figure they will do better, but still
bitter over losing the information from the earier events.
I have around 60TB of spinning disks at home, but will be going tape in
the future.
A lot of my data is conference video and backups of laser show tapes which
often are 8 channels of WAV data @ 48khz, so ~3-4GB per 30 minute show
tape.
