Planned obsolescence:

Also, and this is just anecdotes, but I personally know three people who have had WD drives fail on them this year.

One of my lightning nodes is on a machine running platter drives and it serves its purpose well enough (it's not a routing node, just a wallet for bitrefill etc). I'm more comfortable with it than a raspi anyway :) but I wouldn't trust WD drives for anything important.
