Just returned Pegasus32 R6 as not mountable on M1 mini. Suspect same issue as lack of eGPU compatibility although have not found any other discussion. Any confirmed RAID storage thunderbolt 3 setups out there that are up and running well? (I’m looking to purchase and need something that will work). Apple and Promise tech support were useless. Please help!
 
I read through their post it doesn't look good for now. I'm going to wait for the second gen Mini silicon.
Check out OWC. I would call them and talk to them about their M1 compatible products.
They have been very patient with me. We had a lot of back and forth when Mojave tanked my eGPU. Their customer service is A+. All good for now.

Thanks Meatsuit...confirms what I found...definitely not compatible. Found nothing definitive from Promise except one post from someone purporting to be from Promise (although I'm skeptical)...and he said no support as these are legacy products. For all those who already own these and rely on them I sincerely hope that isn't the case. For me, well, don't care...returned it and went with OWC Flex 8 solution...hoping it will work as stated...
 
I too skimmed Promise's forums for an answer for @jgtuna but didn't find anything helpful. Also bad and strange is that there's something of false, contradictory claims.

Hope not affiliated w/ Promise as this would be a significant miss on their part. I bought a Pegasus32 R6 with my new M1 mac mini and MBP, specifically to use with them, after verifying on both the Apple store and Promise websites that they specifically call out compatibility w/ M1 / Big Sur. Fortunately Apple gave no resistance to my return. But spent >1 hour on Apple tech support. Gave up on Promise tech support after 3 "can I place you on a hold" follwed by 10-30 minutes on hold followed by hang up. Guess they're stumped and can't stomach telling customers "sorry, it isn't working right now and we don't have a solution" followed by either "and we're working on it and expect something by MM/DD" or "and probably won't so might as well toss it in the garbage or return it if you can...good luck"
Even before reading the above post, I (also) saw these listed under Compatibility on the product page.
This thread narrows the problem down to a driver, err kernel extension not being recompiled for arm64.

I've tried manually loading it with kextload and the result is:

Executing: /usr/bin/kmutil load -p /System/Library/Extensions/PromiseSTEX.kext
Incompatible architecture: Binary is for x86_64, but needed arch arm64e
Incompatible architecture: Binary is for x86_64, but needed arch arm64e
Whether it ever will be ¯\_(ツ)_/¯
