Extremely Power Efficient. They have come a long way with idle power and power management. Even on the Desktop where Energy efficiency isn&amp;#x27;t much of a concern. There used to be a time where SSD are 1W+ even when idling.&lt;p&gt;2. The amount of idle time, so these IO traces shown most of the time SSD isn&amp;#x27;t doing anything at all.&lt;p&gt;3. Read Latency are now extremely good. We are talking about sub 100us and sub 200us in 99th percentile. To the point Optane doesn&amp;#x27;t provide any meaningful differences in consumer usage. We will find out soon when Billy mentioned he will be testing Optane PX5800, I cant wait to see that. I should also note before someone jump in about Optane&amp;#x27;s Random Read Write advantage in QD1, I still dont believe it matters in consumer usage beyond the current NAND SSD performances.&lt;p&gt;I think with coming PCI-E 5.0 Drive we have a roadmap that has pretty much &amp;quot;solved&amp;quot; the performance category if we haven&amp;#x27;t already done so. What I want to see is slower, but large capacity SSD that is more affordable. But apart from some unforeseeable market condition, I dont see anything on the roadmap or forecast that could bring us 4TB SSD for sub $200 within the next 4 years. We seems to be entering the end of the S Curve where improvement ( cost reduction ) will be slower.</text></comment>

Many &amp;quot;tech&amp;quot; sites now just repeat manufacturers press releases. Not Anandtech.</text></comment>
