I noticed reviews of Hynix P31 on Amazon stating it wouldn’t work on their Mac’s or had kernel panics ?When the fast cache runs out (some ppl call it eye candy for consumers or cheatsheet for sloppy benchmark), Hynix P31 2TB sustains 1500MB/s write speed until the very last bit. When the fast cache runs out, Intel 660p 2TB sustains a miserable 250MB/s in comparison.
The level of performance and power efficiency that Hynix P31 Gold brings to the competition is unparalleled for the audience of this thread.
maybe I’ve missed something?
One interesting review :
”So like most everyone, I got pretty mad when I found out that this NVME's driver chip was not compatible with Macs. Nonetheless, I tried. I got the same kernel error as everyone else. I tried a bunch of different formats, JHFS+, FAT32, APFS, all would pull a kernel panic on boot. I was going to return the drive, but chose to keep it for emergencies. Alas, a windows NVME failed, and I had this. I ran windows on it until I was able to get a more permanent drive in, and then removed the NVME. I had to transfer large files of a shop Mac one day, so I put the SK P31 in a Mokin NVME to USB-C 3.0 enclosure. Formatted it via disk utility in terminal as an APFS drive on Big Sur, and it worked great. One day I noticed that I turned the Mac on and it booted fine, and showed the P31 as a functioning external. Running Disk Utility, I see that somehow there is a small Windows EFI partition that is a sort of remnant of the initial windows install, but the APFS formatting has also created an Apple EFI partition. That got me to thinking, so I formatted it as APFS again. Copied the EFI off my main drive onto the P31's Apple EFI. Then I kept it in the USB-C enclosure, and rebooted with a Big Sur Install USB. The install booted up correctly, let me choose the APFS formatted P31 as an option and promptly installed. After a few restarts to finish out the install, it successfully would boot Big Sur from the P31 via the USB enclosure. Then I said, why not just plug it into the NVME slot and see what happens..... and it works! I have no idea why it wouldn't throw a kernel panic now, if it was something to do with the onboard driver. But doing an APFS format, copying an Apple EFI or Clover EFI into the EFI partition, and rebooting seems to make it work. This is obviously stupid af but if you have one of these drives around, and you want it on your Mac, give this a shot. For reference, I am running mainly on a Z370n-wifi, i5-8600k hackintosh with Big Sur and the latest Clover. I assume an open core EFI holder would function the same. I later tried this same method, with a factory apple EFI folder, and was able to successfully make a P31 drive function in a A1708 MacBook Pro via an NVME adapter. The adapter is meant for 2230/2242 drives, but with a little ingenuity, it'll fit.”
