NO actual data quantity? Back in post #4 or so I said I am presently at about 400 GBs and expect that to increase faster than in the past due to my hope to start producing some internet videos. I can see being at the 1TB level in a year or three.
"Things like this and even Hot swap in a home situation are overkill and that is before you get to how much power you will finish up consuming." OK, thanks for saying it out loud. And don't worry, I don't have the funds for anything gold plated.
You said, "Both of these are running between 400-500W a day total." That steps into MY area. Equipment does not consume Watts in a day, total or otherwise. The Watt is a unit that measures the
instantaneous rate of power consumption. Look at your electric bill and you will see that you are being billed for kWatt-hours (kWh). ONE kWh is 1000 Watts being consumed for a full 60 minutes. And on my electric bill I am paying about $0.13 US for each KWh.
You could turn on a device that consumes a
million Watts for one micro-second and never notice the change in your electric bill because that would be only one Watt-second (or about 0.000278 kWhs) of actual power consumed. An LED night light, turned on for ten hours would consume far, far more power.
Your 500W device, running all day would consume 500W x 24h /1000 = 12 kWh of electric power. At my present rate that would cost $1.56 USD. Of course, if you are also running AC in the summer months, then the cost of removing that energy (
ALL of it becomes heat) from the building would be added to that. How much would depend on the efficiency of your AC system.
I am not saying that power consumption is not important to me. It is. And anything running 24/7 will have an impact on the bill. Another factor into the compromises here. Boy, that cloud is starting to look better and better. Spare me the "I told you so"s, please.
PS: Money saving tip for all who operate even moderate sized server/storage facilities in the winter: have your HVAC people bypass the AC system in winter with an outside air intake to the server room. And add a fan and a thermostat. Why waste all that cold air outside the building when only one room needs cooling in the winter? And exit the hot air from the server/storage room into the rest of the building to save on the heating bill. Why waste that free heat?
My apologies for the digression.
Seriously some completely OTT advice above here for 'home use' and as far as I can see NO actual data quantity to be stored. Get an 8 bay NAS, Enterprise storage neither of those are 'basic advice' they are advice that Rolls Royce (with Gold plated trim) or you are slumming it
Things like this and even Hot swap in a home situation are overkill and that is before you get to how much power you will finish up consuming.
Lets also consider the jet engine whine of Data Center drive speeds while we are at it in a home use case.
Just running a consumption test on my NAS and NVR consumption to put them on a 12V UPS/Battery partly for data reasons and also physical security ones the NVR runs its own Wifi independant of the main network and if I am part way into. Both of these are running between 400-500W a day total. Power consumption on an 8 Bay NAS heavier processor and enterprise drives long before you get near a home brew PC based solution is what exactly?
