Review on 💨 High-Speed 2TB OWC Accelsior 1M2: PCIe 4.0 NVMe M.2 SSD Card - Lightning-Fast Storage Solution by Junior Samson

They advertise it but I confirm perfect support with 2019 Mac Pro. My only issue right now is that the depth of the rear screw 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.
