You ignorant naysayers and Sony haters can rate me down all you like, but you're full of crap and need to get off your freaking soap boxes. I try and make an educated post with some good ideas and good technical information that's backed up not only by data from others but my own SEVEN YEARS of experience in the video editing industry, and you start rating me down.
"Blu-ray media like all commercial optical media will have a 50+year shelf life. The media format can be either MO or WORM. A long shelf life with WORM capabilities make this media perfect for archiving of mandatory compliant data, Medical Images, Video, Document Imaging and number of other near line archival uses. Because of Blu-ray random access capabilities it is also better suited for small files than our tape technology libraries."

Blu ray disc manufacturers such as TDK also put very solid anti-scratch coating on the discs which also improves durability. I'm sure some of you have had problems with blu-ray and other optical media, but it's nowhere NEAR as unreliable as mechanical hard disks. Rate me down all you want. I know my facts. Are there crappy discs? Yes. Do research and try and buy good ones - Taiyoo Yuden are said to be very good. Many companies make discs that test out at 30 yrs plus. Some of the cheap crap we buy at stores doesn't last two years, like some have said, but I stand by my post, and those who rate my above post down show just how little they know.
Why do I even bother trying to be helpful and informative here. You guys would rather have a Sony-hate party and drink your own negativistic piss. Be my guests.
