What happened to that discovery that flash memory could "heal" itself if heated? Where are the drives with a "bake or broil" setting, and a 1Mil. write lifespan?
Is this some kind of phase change memory technology? Like based on the memristor?
No, standard NAND, but with a "heater" built-in. According to the article link that was posted here, when the NAND ran out of write cycles (3000), all that had to be done was heat the NAND to a certain temp briefly, and it would be "healed", and good for another 3000 cycles.
It sounded like very promising technology, to give us nearly limitless writes on NAND.
Perhaps the industry doesn't want that, they WANT SSDs to "wear out", so that they can sell us another one.
If they didn't, people could buy one of these "super NAND" SSDs, for each of their rigs, and potentially use it for the rest of their lives.
But imagine what they could potentially do to their bottom line if they could cap that?The hard drive industry has survived with infinite write cycles.

Business part MBTF can often be interpreted as an expected near-term failure rate (IE, MBTF/quantity = yearly replacement expectation). Outside of that, it's mostly a number made high enough to look good, but not so high that it's obvious it hasn't come from any meaningful testing.interesting that everyone has that 3000 write cycles to talk about............My SSD says MTBF 2,000,000 hours ...........and that is just the failure, not the life........................maybe just Marketing http://ocz.com/consumer/vertex-3-sata-3-ssd/specifications

It makes real sense for things like brushed motors, bearings that handle unbalanced loads, capacitord, and so on, but anything as mechanically and electrically complex as a HDD or SSD...no way.
