Thanks a lot for all hints Stuart.
The isolated 1TB SSD Samsung PRO 860 drives have some AHCI errors
(OpenBSD_6.9beta-RAID5-3x1TB-SSD-isolated.txt in the attachment).
Writing to an "isolated" drive does not crash OpenBSD even there are
AHCI errors and sometimes an I/O error from dd (see directly below).

I am not able to run the commands above as the root ddb{4} console is
dead (I can see only the last error message but I am not able to type in
using the keyboard)
I will connect those Samsung PRO 860 1TB SSDs to a Xeon based system
(another SATA-controller) and check there for AHCI errors.
Maybe it is worth to mention, that the original RAID tests on Debian
buster with six of 512GB Samsung PRO 860 (the same drives andf RAID6 set
with mdadm) worked without crashing the OS.
Kind regards
