You could. But someone else could add 8 SSD's for the same money and plot multiple times as fast as you, until the SSDs break.

And what happens if the SSDs break? You lose your plot? Has to be right - since it's proof of space? But what then is the use of burning through SSDs so fast?

the SSDs are used just to create the plots, once the plots are created they can be moved into HDDs where they get farmed (checked to see if they can solve blocks for the blockchain)
