If you pick up the random red/green drives that appear in and around your base, those are the ones that explode.
The drives that you buy never explode, but if you mix them you are in for a bad time.
idk, they seemed fine, but i'll keep that in mind
edit: i'm pretty sure i mixed a few of those into my regular drives too so my single drive rack full of old level 0 signals might be a bit of a pick a diiick but it's whatever
