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?Quote:

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.Quote:

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.Quote:
