I’m not a gamer, but I remember their drivers for even their high-end cards were a fucking nightmare on Linux.
It’s not that hard to give the open source community what they need in order to build their own drivers, or enough source for them to get things working properly. This was one of their dumbest moves among many dumb moves.
First, if you have more than one disk, you should be either getting redundancy through mirroring, or building arrays of several disks with redundant methods like RAID5 / RAID6 / ZFS zraid2.
Second, no single copy of data is safe, you must always have recent, tested backups.
