Use case:
only 4 SATA ports on mobo (most common mATX motherboard configuration)
1 SATA port connected to DVD RW (also common)
2 SATA ports connected to original RAID1

OK, looks like a common desktop - good description.

BTW, please, use fate.suse.com if you want to file a feature request.

I'm an openSUSE user. suse.com is blocked via hosts file to prevent doubling or tripling browser history entries for bugzilla.opensuse.org bugs that show up in opensuse mailing lists and forums as bugzilla.suse.com or bugzilla.novell.com bugs.

That said, I've used features.opensuse.org 10 times over past 5 years. Not once has one been implemented. Highest score reached is 6.

IMO, for several reasons, not least of which is its superior search functionality, any FOSS project using bugzilla software for bug tracking should be using its bug tracker for feature requests. NAICT, every Linux distro (and many other FOSS projects) using bugzilla software for bug tracking, does so, except for openSUSE.

User wants to replace entire RAID by first creating (degraded) new RAID1
on larger disk on last SATA port, then rsync from old to new while
booted from DVD, after which remove old raid intact to some other
machine as a backup, and lastly boot from new with other new disk
connected and complete the new RAID.

This setup is, indeed, for very experienced users who made a mistake
while they were partitioning their disks for the very first time. This

My disks get fully partitioned before any installer ever sees them.

use-case has a bit different answer: Use separate data partition, be it
a RAID or not. Have your system on a different partition, again on a
RAID or without.

I fail to see how a separate data partition helps anything. I already have 14 partitions per HD used for RAID1.

Additionally, I'd suggest such user to buy an external USB disk and save
their backup there, having two disks in the same computer especially
next to each other asks for unexpected failures anyway.

RAID is orthogonal to backups. RAID is protection against hardware failure and downtime only. Data restoration isn't the same ordeal that hardware replacement is.

I have upwards of 20 machines using current openSUSEs. Only one provides USB3. Until someone offers free replacements of those machines with machines having USB3, USB will remain an emergencies-only option here, as pre-3 has always been, painfully slow compared to ATA when GB number triple or quadruple digits, and due to unpredictable device enumeration with mixed buses, more complicated for preparation of new system disks.

But thanks for your use case, Felix. It's still a valid one, while I'm
afraid, it will be quite rarely used.

You're probably right. Only the majority matters any more, unlike with the pre-open SUSEs I remember. :-(
