I would imagine power use idle and or in use would be that much lower power use then it is, I am aware when talking the "edges" of things where wins are often counted in the 1000s of a second and all that
still, that seems quite a bit of power when there are "consumer" level ones ( 2280 and such drives) that are getting similar if not superior performance, sometimes capacity, certainly better in the wattage range considering
maybe due to extra something something needed that chews extra power or ??
example I am using for high performance, total endurance etc, Samsung 970 Pro, seems they have managed higher overall performance for a little less overall power figures as well (maybe the enterprise are designed to be 24/7 vs even the sammy "Pro" is not (just a higher grade then normal stuff ?)
The biggest reason enterprise drives have high idle power is that they don't really have any kind of sleep state. Waking up from sleep is a relatively slow process for consumer SSDs, and it's enough of a pause to completely ruin the latency metrics that enterprise drives aim for. Even with sleep states disabled, we usually don't see 8-channel consumer NVMe drives pull much more than 1W at idle, so 4W here is clearly a lot higher. But it's definitely in line with competing enterprise drives (eg. Samsung 983 DCT idling around 4W for U.2, 2.6W for M.2).
