2.5" 5400rpm HDDs are the most power efficient in my experience. They use around 1W when in normal use.
SSDs generally use power according to their actual utilization. The faster they are the higher the power consumption seems to be. SATA SSDs are generally slower and fall into the 1-3W bracket, NVMe SSDs are more like 5-10W, especially the PCIe 4.0 ones.
Don't quote me on these figures, I have not extensively tested them and they are very rough ball-park ones.
With what I saw with me current HDDs I wouldn’t have though smaller HDD would be the most power efficient. And now I understand better why sometimes I read HDD can be more efficient than SSD.
Any brands/models you would recommend?
I don't think the power efficiency of the different brands is that much of a difference that it makes sense to only buy specific ones. For SSDs it is rather important to buy from reliable vendors that are not only repackaging the cheapest nand chips they can currently find on the market. In the past Samsung was always a good choice, but my most recent purchase of a PCIe 4.0 SSD from them was not so great in regards to reliability, so I am starting to wonder if they are cutting corners somewhere these days.
Ok thanks!
