The whole “SSD’s lose their data if they’re unplugged” is a bit of a moot point especially if your plan isn’t to bury it underground for centuries. That said personally I’d still go for HDD mainly because you get 4+ times the storage for the same price. If you only need a terabyte or so and the amount of data isn’t going to grow then sure, SSD works just as well.
