Two RAIDS, both APFS, one recognizes the format, the other one doesn't. Is that normal?
The one with the unrecognized format (which is only 7 days old) is also giving us crazy slow-down issues after a bad kernel panic after the computer went to sleep and SoftRAID locked the drives. I can't even get access via BM Speedtest. Multiple restarts and no luck. Any thoughts what could happen here? I am on BigSur 11.5.2
FYI, I noticed I don't have full disk access for SoftRAID. Does that matter?
Thank you.

You should give SoftRAID application full disk access, so the app can talk to the disks.
I am not sure why SoftRAID app can see the APFS in the volume it does, generally it does not support APFS for the most part.
Can you get me the first 100MB of the drive? We may want to send it to Apple for evaluation. Also, with a System Diagnose report. Do both with these terminal commands and let me know when you have them:
sudo dd count=100 bs=1m if=/dev/rdisk12 of=~/Desktop/Tatooine
(If you have a problem saving the file, let me know, we may need a more specific path)
sudo sysdiagnose -f ~/Desktop/
After you do this, then backup/erase the volume with Disk Utility (as APFS). You cannot erase a SoftRAID HFS volume as APFS, but you can erase an APFS as APFS in Disk Utility. See if that helps with performance.

@softraid-support Thanks, since I have to start from scratch, would you just recommend to do a RAID as HFS+ instead of APFS? There really isn't a benefit to APFS, isn't it?

With HDD's, HFS is faster.
With SSD's, APFS takes better advantage of the capabilities of the drives.
APFS is more "reliable", i.e, more immune to volume directory damage.

@softraid-support Thanks. I am using HDDs. So you would recommend HFS? And since SoftRaid still has occasional hiccups with APFS, wouldn't at this point HFS disk be more reliable somewhat? Ironically what I had was a SoftRaid LOCK after the computer went to sleep by accident (silly me) that caused some volume damage on my APFS drive...
Looking forward to your advice. Thank you!

Keep in mind that inside a volume is a container that macOS manages entirely, not SoftRAID. We recommend HFS for HDD's primarily because of performance, HDD performance over APFS can degrade quite signicantly over time, and be more than 50% slower than HFS.
There are no known "hiccups" with SoftRAID APFS volumes. Can you give me more information? did you have a volume that was damaged when for instance disks ejected from the system momentarily? (the thunderbolt crash/reset issue) We are very interested in trying to get Apple data any time there is an APFS corruption issue, this is the future and APFS should have minimal issues with volume/file system damage.
