Re: NAND flash misery

Un bel giorno Vladimir Vassilevsky digitò:

Guess how many bad blocks are typical for NAND flash of several GB
capacity? As many as 2 percent!

If with "typical" you mean "the grade used for low-cost consumer
electronics", you are right. But NAND normally come at least in two or
three different grade options: no bad blocks, 2% initial bad blocks without
dynamic bad blocks (until the minimum number of erase cycles), 2% bad block
with dynamic bad blocks, etc.

I was under impression that flash is more reliable then HDD; now I see
that it is not so. Do you know how reliable are the IDE flash drives?

I believed that solid-state drives would have taken over a lot easier, too.
Instead the good old rotating junk continues to resist very well, except in
very hot or very vibrational or very space-restrained applications.
