Just too far ahead of it's time. Such amazingly fast peristent stoage, nothing like it.
Trying to put it in DIMMs was a bad move because those slots are needed for much higher speed ram, but the pcie versions are just out of this world awesome. Throw a 70/30 read/write load at a nand ssd, or throw small writes at it, & watch it crumble. Optane truly didnt care. Incredibly great technology. It deserves many more lives.
- bcrl 4y agoThe problem is that Optane wasn't better than the other NV-DIMMs that came to market. It's easy enough to build an NV-DIMM based on DRAM with some buffers that dumps to flash when the power fails, which ends up being cheaper and easier than Optane memory based DIMMs due to the required error correction and wear leveling. It is quite likely that persistent memory will make its way into general purpose computers in the future, as the difficulty in scaling DRAM increases as cell sizes decrease. Capacitors can only be made so small before they don't store enough charge to overcome thermal noise. In theory Optane was supposed to be better at smaller feature sizes, but it never got to that point. We'll have to see if MRAM or NRAM can make it in the coming years.
