Engadget said:Sure, it's just a prototype for now, but we can't help but feel a bit smitten with any drive capable of playing 100GB of data off a single 4-layer optical disc. The BD camp was also touting 200GB, 8-layer discs as they have since 2004 (at least) while showing off the components that will usher in 8x performance (double-that of existing commercial gear) in a more realistic timeframe. When that might be exactly, no one's willing to say.
The main market for disk such as this [IMHo] will not be for movie storage (although LOTR super Extended HiDef on 1 Disk Would Be Beautiful)
but more the realm of user backups , but in the time where 500gb can be bought for £50 is there a need for a $xxxx burner and $xx disks ?
