How to solve a problem with setting up a RAID array?

Question

Iron

They installed a server for me on Hatzner. For my RAID controller . you can additionally order a caching system .
Is it worth fooling around with the additional configuration of a dedicated server? In my case, when an SSD is installed (for a data center) and a SMART monitoring system is configured.

Answer 1

If you have normal SSDs (and for hetzner you need to find out this separately - they can put frank garbage under the guise of datacenter ssd) - then you don’t need a RAID controller at all.
Unless you know how to accurately configure this controller to work with SSD. Otherwise, you will run into the performance of the controller, and not the capabilities of the drives. RAID controllers have not kept up with good SSDs for a long time

Answer 2

The question is impossible to answer.
In general, it is not clear what your task is and what requirements and what exactly you need.
