Recommendation for low power SSD (derpzilla.net)

I’m trying to improve the power consumption of my NAS. The 2 (7200 rpm) HDDs I had were using 15W at idle and 5W when spun down. I’m reading a lot of conflicting information about what is lower power between HDD, SSD and NVMe SSD. Eventually I started looking at SATA SSD (please let me know if this is not the most power efficient)

I found this site that shows a benchmark of different SSDs and their average power consumption. I was about to go with WD Red but then I found a YouTube video saying I shouldn’t go with WD for a NAS.

Can you tell me what brand or model you’re using in your homelab that’s power efficient? Ideally I would like 4TB SSD.

Thanks!

Maybe you are looking at the wrong thing. CPU + motherboard controllers idle state matters more than spun down hdds

I saw a spreadsheet somewhere of a lot of cpu + motherboard combinations with idle power consumption for ultra low energy NAS optimisation.

The issue is that’s it’s too late… I already have my NAS. The only things I can optimize are the disks

Still you can calculate how much you will save with 2w power reduction with selling this one and buying different NAS.

You can reduce the disk idle time after access to 5-15 min for better power saving.

Yeah whatever I'm doing is bad, 5800x in 65w eco mode and asrock pro4m "idles"(all hdds spun down) at like 150watts. I run like 20 dockers on it so I don't think it ever really idles
