12x BD writer should be priced at US$10 by now, 14x at US$15, 16x at US$18, and so on.
There are some important reasons why it is not so, but the most important one is because BD-R and BD-RW recording became obsolescent before the BD drive manufacters and licensees could take their collective efforts to decide when to make BD cheap and mass products. Both LG and Samsung lost much of their interest in optical storage by early 2000s because profitability was virtually zero even then for their CD-ROM, CD-R, DVD-ROM, CD-R/DVD-ROM combo, DVD+R/-R, and Super Multi drives. Yearly sales amounted to one or two billions in US dollars for each of the largest market share leaders and it was extremely labour-intensive work at the drive assembly lines. Those optical drives are also heavy and big requiring too much for inventory and shipment.
These companies have yet to PROVE to the enthusiast crowd that writing faster will allow the data integrity to "stick around" as long as we want it to..
Store on RAM-based drives if you desire to spend less time on storing and need to enhance data integrity.
