If you live in a high energy cost area the ROI on going SSD can be as low as 3-4 years

~$800 on two 8tb SSDs

2 x 8tb HDDs is roughly $200USD

I don’t know what kind of electricity prices you’re paying, but to hit a 3 year ROI on your SSDs, you’re paying at least $2.2USD/kWh, assuming the full 15W (232kWh/year total) consumption of the HDDs and assuming negligible power consumption from the SSDs.

Edit: average power consumption for HDDs read/write operation is usually around what you claim them to idle at, with actual idle consumption below.

Edit2: and to be fair I did take refurb HDD price. a refurb SSD is around $300 USD for 8tb, bringing the minimum power cost per kWh down to ~$1.7USD/kWh for a 3 year ROI.
