I have a few IDE drives around for some of my experimental/ project pcs. 40gb or so.

I have also had to replace a 500gb or two in the raid5 array I use for main storage on my primary NAS.

I try to avoid buying things like 20tb drives on black Friday because if a drive is going to fail, it probably won’t be while there is a sale going on and I do like have a spare drive on hand.

I did pick up two 2tb drives yesterday, but that is because I am finally at a point where I could replace a 2tb drive in an emergency. I still plan to run them mirrored.

Don’t worry, you just need to wait for the EU to mandate EVERYTHING run off usb-c.
