Works in classic Mac Pro
Installed this in a Mac Pro 5,1 with western digital M.2 SATA drives and it works fine. All drives were seen in Disk Utility and could be formatted. The fan is a little on the whiney side so I have since disconnected this as the card is getting airflow from the case fan anyway. Would recommend to anyone with a classic Mac Pro that needs faster storage than the SATA ports on the motherboard. Not as fast as NVME but a great way to increase the amount of faster storage in your Mac Pro.

Works exactly as expected, plug and play
Bought this to make use of some SATA m.2 drives in my media server. These would be e-waste without this adapter

Great IF you use "b" key m.2
Returned item as "b" key m.2 are very uncommon , the "m" key version is a ridiculous price !
