So by my calculations the included 512GB card will last just shy of 2 years?
(((512−412.19)×1,000)×10)
÷60÷24÷365=1.89897 years

Bitcoin blockchain is 412.19 GB so multiply by 1000 to get MB.
Each 1MB takes 10 minutes so we multiply by 10 to get total minutes which is 998,100 minutes. Then divide by 60 for hours then 24 for days and finally 365 for years.
