    Intel SSD 665P Series Neptune Harbour Refresh launched

    Client segment M.2 NVMe SSDs use SMI2263 controller and 96-layer 3D QLC NAND.

    Glad they increased the endurance of the QLC drives here. I have a 2TB 660p and have written o ver 50TB to it since I have had it so the extra endurance of the 665p is welcomed

    Just a thought, were they very conservative on the original endurance specs to avoid returns with unproven tech? I have an Intel X-25M at 80GB which was my very first SSD for use as a boot / programs drive. It has been in for 9 or so years and it's still in excellent condition. It certainly didn't come with any kind of expectation of this kind of endurance specified. It's possible that with experience they have just increased the endurance spec of the existing tech?

    They seem to always be conservative on endurance. There are plenty of things they can do to influence endurance, so even with largely existing tech they might be driving the flash cells slightly better and extending their life. Or to put another way, I'm not convinced endurance is a big enough selling point for Intel to specifically game it, so more likely better endurance just falls out of general improvements.

    Those early SSDs from 10 years ago used dual level nand, and much larger lithography, than current SSDs with much smaller QLC cells. This means via simple laws of physics that far more electrons are used to store each bit of data, so the cell will last much longer before wearing out, so we should not be surprised that it lasts well. It is simpler, and does not rely on such tight tolerances.

    Bit like how the highly stung engine on a modern F1 race car will only last for a season before blowing up, while the smoky old diesel on a London bus is still going strong after 50 years.
