@PierreRochard Pros of HDD: Large volume, cheap Cons of HDD: Very poor random access performance Pros of SSD: Turbo random access performance & sequential performance Cons of SSD: Small volume, relatively expensive
The UTXO database (chainstate) is heavily accessed, which is quite a nightmare for HDDs. Storing gigantic block data on a SSD is quite a waste, because it’s not frequently accessed.
Therefore, it’s optimal to use HDD for block storage only, while SSD is supposed to deal with heavily accessed chainstate/txindex etc.
“Migrating block storage” could be worded in other ways, like “migrating chainstate to your turbo SSD to significantly accelerate syncing process”.
