Is there some obscure use case scenario where *maybe* you could run a node with an HDD?

I know.. I know…

"it is impossible to sync with an HDD"

​

But what if I didn't care about syncing? All I want to do is keep a historical record of the blockchain for my own massive historical querying purposes. I don't care if it lags behind the current chain even a couple of blocks.

​

HDD is so much cheaper than SSD, especially if I want a full historical set. 40Tb SSD is going to be ridiculously expensive.
