Hello,
My notes explaining how to do this are available here: https://github.com/gene-git/blog
If you could explain the benefits, we could write a ArchWiki page on this using the notes you have provided. I do believe though that hardware RAID 1 would be better, but if you do not have the ability to do hardware raid 1, then this does seem like a very good idea. The issue is you need to keep both disks syncronised, which I have seen you have done using a script, but RAID syncronises during writes, just like you were writing directly to the disk, not to two disks. Also another benefit of RAID 1 is because the data is contained on both disks, you theoretically double your read speeds, while the write speeds remain the same (as it is not striped). -- Polarian GPG signature: 0770E5312238C760 Website: https://polarian.dev JID/XMPP: polarian@polarian.dev
