Number of rewrite cycles? + Which disc drive can write DVD-RAM at ×16?


#1

Many LG and WriteMaster™ drives could reach ×12 PCAV for reading and writing (also PCAV for reading somehow).
Not ZCAV, because CLV makes ZCAV obsolete. ZCAV does not even exist in disc drives.

However, I do not know any drive, which reaches full ×16 speed and what happened to cartridges, and also:
How many rewrite cycles do higher speed DVD-RAMs and HD-DVD-RAM have?

Version 2.0, first generation (usually supported by desktop and slim drives):

  • 2.1: ×3 = 100000.

  • 2.2: ×5 = 10000 .
    Version 2.0, second generation:

  • 2.3: up to × 6.

  • 2.4: up to × 8.

  • 2.5: up to ×12.

  • 2.6: up to ×16.

  • HD-DVD-RAM: Unknown speed, unknown rewriting cycles.

  • DVD-RAM Version 1 line: Unknown.

  • DVD-RAM2: Unknown

How can the finished/remaining cycles be calculated/determined on all rewriteable discs?.
