The thing is, whatever the name here contains, a server is a server, by definition. If i find a server to be too noisy, then your planning beforehand went wrong.
It is a known fact, that HDDs make noise, so if i plan on using something with HDDs 24/7 i have to accept some kind of noise, eliminate that noise or aim for a location, where that noise doesn't matter.
But i shouldn't complain about a Windows Server not spinning down HDDs because that noise is driving me crazy. IMHO something went wrong before.
Look, the world has changed. A server is not a noisy big box which runs on 200W in a rack, but something which people keep in their living room! Look into the market of NAS devices! These brands like Synology, QNap, etc. have grown exponentially in the last few years, for providing an easy to configure and SILENT server which anyone can keep always on in their living room!
Look into any Amazon review: you'll keep looking that people LOVE these little servers because they are quiet. And HDDs use a lot of power, the power usage is DOUBLE for spinning <> idle HDDs in a NAS.
Read this review for example:http://www.smallnetbuilder.com/nas/nas- ... 3-reviewed
Power consumption measured 31 W with four WD Red 3TB 7200 RPM (WD30EFRX) drives I supplied spun up and 16 W when the programmable drive spindown kicked in. Fan noise, in the default "Quiet" mode (the other two modes are "Cool" and "Low-Power") was barely audible and there was little idle drive noise in my quiet home office environment. So I rated the 413's noise as low.
