Not a dumb question! If you're talking about spinning rust, this is precisely the job of some particularly niche sysadmins (the kind that manage storage clusters) to know. I'm not one of them, but a quick search produces this:
The easier answer I'm comfortable giving (despite me not being a sysadmin by trade) is that good storage software/setups should abstract over and protect you from something like this, because SSD/HDD bit-rot is absolutely a thing regardless of orientation -- if you're not using a WAL-ing (ex. zfs) or checksuming (ex. ceph's Bluestore) file system you're exposing yourself to data corruption. Only thing left is whether you'll actually have your drives long enough for them to exhibit complete failure from orientation, can't know that except to test like Backblaze/other providers do.
