You can calculate it !
Take your power usage and compute the cost over a year.
I will soon add a SSD because i finally moved from a RAID 1 to RAID 5 (so more HDDs), it consume more electricity.
I calculated an additional between 20-30€ a year of electricity, adding a SSD for read/write cache would allow the HDDs to stop spinning, make things faster and will be cost effective over a few years.

essell@lemmy.world 3 days agoI hadn’t considered that! Thank you.
I’m hoping the OS, as it’s designed for this, is going to be helpful in getting the right balance with power usage.

This is why I’m using a refurbished mini PC as my home server. Lower wattage for constant uptime at home. Also very quiet.

Bingo! I’ve got 4 mini-PCs (does a 2014 Mac mini count?), and one SFF. The average power draw of this cluster is barely ~90W.

Yeah with that win10 EOL there’s loads of refurbs out there for cheap.

Only one of them is compatible with Windows 11 lmao - HP Elite G4 mini with an i7-8700T. Everything else is 7th gen or 4th gen.

To put this into perspective for you, if your NAS sits at idle for 90% of the time (probably true) and an older CPU is 50w (kinda high, but maybe) and a newer CPU is 15w, over an entire year it will save you around 305.76 kWh. Average price per kWh in the USA is 12.89¢. So over a year a new CPU can reasonably save you around $39.41. So it’s not nothing, but it’s nothing crazy, but lower idle wattage = lower temp = components last longer, which is the real savings.
If an older CPU is only gonna last you 5 years, when a new might last 10, you’re going to save almost $400 in energy and generally a CPU today is going to be cheaper than a CPU in 10 years (probably^tm).
