Review on 💥 Boost Your Mac Performance with OWC Accelsior 1A PCIe NVMe Flash SSD Adapter Card by Nick Santos

They advertise it but I confirm that 2019 Mac Pro has perfect support. My only issue right now is that the rear screw depth puts a lot of pressure on the M.2 SSD when the screws are fully screwed in. The pressure actually bends the m.2 in the middle, which of course has a negative effect on the drive and reduces contact with the cooler. Your M.2 drive may come with a thick copper sticker that you can remove to make this easier and/or screw the screws in about halfway. Look at the heatsink from the side to see if the M.2 is flexing underneath. Slightly shorter screws should be included with OWC.
