Those memory/drives, can they stand infinite write cycles? Because flash memories can't.
Mechanical drives can't either.
Of course they can. The limit is in the thousands of hours of usage, not in the write cycles. There is no wear on the surface or the head because of changing the magnetization. They don't touch.
How many infinite writes do you get per thousand hours? Mechanical devices wear whenever they're used. Heads crash, bearing wear out. Why else do drives fail? They don't last forever.
But the point is that flash RAMs have an "asymmetry" between reading and writing that does not exist in magnetic media. There is (with current technologies) an upper bound on the number orf writes (but not reads) that can be performed on a flash RAM that has no counterpart in magnetic media.

With that, you raise the question of how often you write vs read. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
