Nvme takes the win for me, nothing beats the reading and writing speed of Nvme, I am currently using two Samsung 970 EVO Plus in my PC and the difference is performance is marginal.
Are you run the bitcoin blockchain with that nvme?. how fast when compared it between old HDD?
I don't know what is the maximum age for the SSD?. but when read that article, 2 years is the maximum reached. so this is very inconvenient when running the bitcoin wallet is limited at that time and moving to a new SSD when reached maximum after 2 years.
