RAID 50 doesn't really solve it, it exposes you to some more risk since you can still die with 2 disks but now you have more disks in each sub array.

The correct answer is either a 3-mirror RAID1 or RAID6.

Bcachefs also promises some solution to this by allowing both erasure encoding and replication to co-exist, according to it's documentation.
