These universal statements are almost never true. What means “most”? All 3 that I have are more, some up to 25W. If they are “new”, maybe. Not many that you can get on eBay are old enough that they will draw a noticeable amount. Add always, “it depends”.




Just a side note: these days there usually isn’t any overhead for having a drive encrypted, the CPU isn’t even involved. The drive itself will decrypt the data itself.
Again, let me emphasize: usually. There are exceptions.
