Hmm. Let’s say I add 6 SSDs, 2TB each, for a total of 600€. In a RAID6 configuration, that gives me 8TB of storage. Compare that to a classical NAS with 2×8 TB HDDs for a total of 350€.
The HDDs will draw around 4W idle each, 8W in total. Assuming 0.3€/kWh, over a span of 5 years, that is approximately 100€. The power consumption of the SSDs will be negligible.
So, just in terms of storage, the SSD solution is around 33% more expensive over 5 years. If you include the cost of the NAS itself, the price increment is even less noticeable.
Exactly, it's very small for a "NAS", that's the main advantage. Sub 1liter if my math is right.
