Apples only option is RAID 0, however. And you won't have this issue with RAID 0 in SoftRAID either.

the RAID 5 issue is some kind of threading or pointer issue.

-Select reduced security and enable this:
Select the “Allow user management of kernel extensions from identified developers” checkbox to allow installation of software that uses legacy kernel extensions.
-After enabling third party extensions, reinstall the SoftRAID driver, and go to System Preferences / Security to "Allow" OWC as an identified developer

Then installing the latest beta, I've had zero mounting issues, zero issues using the product, and my workflow has sped up significantly. I feel as though my Thunderbays even perform better with this new system. If you're on the fence, take the plunge. M1 Max is amazing.

AJA is more precise. Try using it, even the Lite version.

Settings are any high end video resolution, 64GB file size and RGBA codec (reduces CPU requirements)

Then see what you get.

I tested with Blackmagic Speed Test. It`s a much used program among filmmakers

What are you using to test?

Note, another solution is a clean install, not using Migration Assistant (which imports whatever macOS setting is triggering this)

Let me know how you are testing. best is using AJA System test, 16GB or 64GB file size, any high video resolution and RGBA codec.

I tested RAID4 and RAID5. RAID 5 was over 100 MB/s faster in read and write speed than RAID 4. So RAID 4 is no option for me. Please fix it, or i will give the Thunderbay back. 

Hardware RAID enclosures generally use inexpensive controller chips, they generally do not contain RAID 4 as an option.

RAID 4 is the same functionality as RAID 4. On RAID 4, the RAID parity is on one disk, rather than spread among all 4 disks. But the end result with modern disks is the same.

Yes, with RAID 4, you have the same protection as RAID 5, if any disk fails the volume will still work.

Why can't I choose RAID 4 with most of the other brands when it's almost the same as RAID 5? Do I have protection with RAID 4 if a hard drive breaks? Because that`s the reason why i bought a Thunderbay. 

I think the M1's are great, but as you read, some users have issues with kernel panics. My current guess is it is 3% of users, but it is really hard to tell.

If you use RAID 4, you can bypsss this issue.

M1 even speed up disk performance, especially SSD performance.
