主题：【原创】用Windows Vista能有快感吗？ -- Highway

I still remember an ancient paper on this topic that I read 10 years ago.

Here are the main points:

1. The limit on erase cycles is a soft one: the time to erase old content is

gets longer, and the cell is deemed failed when the time reaches a certain

threshold. But failed cells may still be valuable if the system manage

them intelligently.

2. The performance of many chips were under-rated. As an example, a chip rated

at 10000 erases was still usable after 2 million writes.

3. The system needs a garbage collector to reclaim freed cells and black-list

failed ones.
