I have Softraid 6.3 on macOS Monterey 12.6 on Intel. I have a RAID 4 in a OWC Express 4M2. Recently the performance of the drive got weird, so I did a validation which reported one of the SSDs had a read failure and to replace the drive. Now I have a new SSD that passed a 3 pass certification (in a OWC Envoy Express enclosure). In the 4M2 I replaced the dodgy drive with the new drive and added it to the array. It started rebuilding and then went to waiting for mount.
I've rebooted and tried to mount the volume, but it is still stuck.

If I try to mount the volume with Disk Utility, I get this error:
Could not mount “Super Scratch”. (com.apple.DiskManagement.disenter error 49218.)

Do you have access to Disk Warrior to rebuild the directory? (you need Big Sur or older, however)
the directory must be damaged, so the volume cannot mount.

It is an APFS volume. I think that precludes DiskWarrior. Is there something else?
If the directory is damaged (and it seems like it could be) how did it get damaged? More specifically, why did the rebuild seemingly start then stop right away? It seems to imply (yes, I'm just speculating) that SoftRAID damaged the directory, doesn't it?

Yes it precludes Disk Warrior, if APFS.
SoftRAID's driver is like a traffic cop. It does not write to "files", it does not understand files, it tells MacOS which disk to write to, only. that is how the Apple RAID driver works.
I don't understand APFS. It is supposed to handle volume directories much better than HFS, but on external drives, is nowhere near as robust as Apple engineering claims. Internal disks, yes, but external? no.

Does that imply I should go back to using HFS+? Even with SSD setups? How does the performance compare? I assume there's a performance penalty, but is it a lot or a little?
DiskWarrior doesn't work on Monterey and later. It seems like we're in a weird no-mans land with a filesystem that's not as reliable as we'd like and no tools to help, regardless of filesystem, on modern versions of macOS.

I agree. I still generally use APFS on flash, as they backup quickly and less inconvenient to restore when required.
