Hello, JW:

Oh, I was already aware of "wear leveling," but, didn't know about that "2
million writes" stuff.

Thanks, for the info!

If you knew about wear leveling all along,
why do continue to post your paranoid claim about flash memory "wearing out"?

Hello, Eric:

No "paranoia" involved, wise guy. <g> Besides, if the Windows "page file" is
enabled, even 2,000,000 write cycles will be used up, pretty quickly -- wear
leveling, or not.

Raving Lunatic. Page file I/O is *much* less than your total I/O. Get some RAM if not.

Easy to claim, hell of a lot harder to actually substantiate that claim.

What matters is the write I/O. Your claim is just plain wrong with many Win systems.

> Get some RAM if not.

You still get page file write I/O even with the maximum ram the system can handle.
