Shigo_Naito Posted December 13, 2019 Share Posted December 13, 2019 Hello, I am looking to see if anyone has some general real world power usage differences between using SSDs vs. HDD in Unraid. Mainly being that I run a simple 20 drive storage server and when not in us each HDD drive sleeps, would I see any real differences in usage upgrading to SSDs? Thank for the help Quote Link to comment
testdasi Posted December 13, 2019 Share Posted December 13, 2019 You need to check the spec sheet of the HDD / SSD model because they do have a large variation. Generally though: HDD sleeps (spin down) at about 0.25W, idles at about 3-5W, operates at 4-8W and uses up to 20W while spinning up. SSD sleeps at about 0.002W, idles at about 0.50W, operates at 2-6W So if your HDDs are in spin down most of the time then the power usage diff would be rather insignificant. Quote Link to comment
