Research RAID more effectively.
RAID-10 is far more efficient not only as a transfer speed but also as redundancy across large arrays. It’s only nerf is storage inefficiency.
RAID-6 requires serious computing oomph to create the parity bits, which dramatically slows down writes and rebuilds. It also needs only two drive losses across any one array before the whole array dies. Conversely RAID-10 has only duplication, no parity, so compute load is far lower and writes/rebuilds are a lot faster, and it can have up to half of all drives fail before the array is irretrievably broken.





For many places, it’s operational inertia. If you’ve had a hosting account at the same place since 1998, you’re bound to still have username/password access to services like FTP even though other (and better) options exist.
And then there is the issue of sole control. Many greybeards like myself still run traditional username/password auth on services because,
So while my setup is not ideal, it is ideal for myself. if I had anyone else as co-admin, or even clients, things would get stupidly complicated very quickly. But since it’s just me…
