Now configure the SSD partition as bcache and enable writeback policy.
This will increase the performance of the rust array to SSD level for
writes, and for reads after frequently accessed data is cached in
your SSD.

+1 :) you may also try enhanceIO, flashcache...

i am barely new to this issue. What would you xfs guys recommend me?
i prefer things i can do with kernel, so its dm-cache? bcache?

the raid is an raid5 with 3 disks at moment. xfs filesystem.
do i have to format it again and set special things?

i use nobarrier at moment,

any hints or links or guides or even tipps from you directly would be great,
