Erm. You just doubled your failure rate. There are times when
that's worthwhile, but if you want performance, SSDs are a
better way of getting to it.

I think my company is in the medium-sized datacenter group. We
use 8-14TB 3.5" spinning disks at prices pretty similar to what
you've got above, and 0.5-8TB SSDs at prices... above what
you've got below, but not breathtakingly more expensive.

ext4 on MD RAID1 and 10, ZFS in equivalents.
