Re:Intel Announces Optane DIMMs

Intel's trying to keep the performance numbers under wraps for at least several more months. My predictions: write performance for a single Optane DIMM will be less than an order of magnitude better than an Optane NVMe SSD, maybe only twice as fast. Read latency might get close to that of slow DRAM, but you'll still notice that Optane is slower.

I wonder if Intel is trying to keep the endurance number under wraps. If they can't beat the current drive writes per day spec it is like having a 10 gigabit internet connection but a usage cap of 1 gigabyte.
Endurance should be fine, orders of magnitude better than flash. Just some temperature wear.
But the speed and density seems to be a problem. E.g. it's still 2x slower than DRAM, but theoretically should be faster. It could also have 3 bits, not just 2.
