I am like Voodoo in the sense that I told myself not to spend any more money on Chia yet I have. I went out a few weeks ago and there was a sale on an SSD 1TB at Walmart. Best Buy had a 5TB USB HDD on sale (that Walmart didn’t come close to). I got both. The main reason I purchased them was so I can pool to the 5TB drive and leave all my plots alone till the 5TB is full, then wipe a drive and start over with the pool plots.
I am of the mindset that I am not to purchase anything else for Chia at all. However, I am still occasionally looking for sales/deals on drives or servers/JBODs. If the sale or deal is too good to pass up, I may go for it, but I’d have to look at it in the moment. If I purchase anything else, it will be something I can repurpose if and or when I stop doing Chia.
