Remind you, transfer throughput improvements from HDD to SDD had limited effect on perceived performance; the reduction in latency was what made SSDs magical (compare normal USB stick to USB sticks with SSD controller). Optane when they manage to get it to original promise and optimize software around it, should yield a similar latency reduction, making them feel much snappier than current SSDs, though throughput-wise they might not be so shiny.
- the_jeremy 9y agoI didn't see in the article anything talking explicitly about latency reduction. I know SSDs have much lower latency than HDDs; could you expand / provide stats on how 3D Xpoint's latency compares to SSD?
- mozumder 9y agoI have an Intel i750 NVMe SSD. It has about a 60 microsecond latency. This device is supposed to be on the order of 10 microsecond. The only people that would notice that are people running database servers serving hundreds of thousands of users.
