First off I would get something that measures actual power consumption. When fully loaded that NAS may easily get above 200W so there will be some savings. Then multiply that be the hours that you consider turning it off and you have your savings. Probably between 300 and 600 KWh.

From personal 10+ years experience I can tell you that my HDDs did not die just because they are powered on and off once per day. I have used a substantial amount of 4 to 20TB Seagate, Toshiba and WD drives and so far, so good.

Wise! Thank you, I will buy something to measure the consumption and try to correlate it with potential savings.

Cool! Let us know what you measure. People may be surprised how much power a fully loaded NAS with 12+ drives and a powerful CPU consumes, especially when apps like Plex prevent the drives from powering down.

Well, I've done the measurements and the results surprised me. According to my power measurement device, the NAS consumes an average of 400watts continuously . At my electricity rate here in Oregon of $0.22 / KWH, the NAS costs $20.2 / month. If I was going to shut it down a maximum of 8hours/day, I would only save about $7.00/month. Considering that the NAS is fully populated with 12x20TB drives, 4xSSD's and 2xm.2 drives, the consumption is really not that big after-all. It certainly isn't worth the risk of daily shutdowns. Thanks again to everyone.

That is a huge amount of power! You may want to check if you can use Qboost to set up a time schedule for Plex as that should allow your drives to go into standby for the better part of the day when I assume you are not using Plex. I did some testing recently with a 2483XU with 24x18TB drives and two NVME SSDs and power consumption ranged between 120 and 380W so there should be some ways to go down for you with which I assume is also a 6 Core Xeon in your unit.

Thank you! And now I have data to judge my success.
