And after all this bad experience just at the beginning, you still want to
have a hardware RAID?

Anything involving a custom driver will be a problem whenever you
upgrade kernel or upgrade the operating system. An incorrect lock
or synchronization (it happens easily on out-of-tree drivers) can
destroy your data.

If the driver is already in the kernel, you will not have these
issues, but, you will certainly have to face others:
- possibly slow BIOS scan (and "keep fingers crossed" config utilities)
- possibly proprietary format on disk (if the controller dies, you lose the data)
- excessive abstraction of disks from kernel (good luck running smartctl on simulated disks)

As already suggested: evaluate a software-RAID (mdadm) setup.
You will probably be convinced by what you'll get.
