Re-writeable DVD's are supposed to have a limited number of rewrite
cycles depending on the type of disc. The following link gives the
approximate number of rewrites as 1,000 for DVD-RW and 100,000 for
DVD-RAM. This and other articles I have read never link lifetime to
read cycles but to age and/or rewrite cycles.
