SensicoM.2 NVME SSD Convert Adapter Card for MacBook Air Pro Retina (Year 2013-2017), NVME/AHCI SSD Upgraded Kit for A1465 A1466 A1398 A1502 (Black Long Adapter)

Works and fits well with my MacBook Air 2015. I paired it with a WD 1TB SSD. Very easy to install with decent performance

I bought this ssd (Western Digital 500GB WD Blue SN550 NVMe Internal SSD - Gen3 x4 PCIe 8Gb/s, M.2 2280, 3D NAND, Up to 2,400 MB/s - WDS500G2B0C) and this adapter:When I tried 'Internet Recovery' in my MacBook Air, the disc wasn't recognized at all so I thought something was wrong (Maybe the adapter or the ssd itself, I didn't knew).I had to go to a friend house that he has a MacBook Air Early 2017 and after we did the same, it was recognized as expected in the Disk Utility. I've formatted and installed Big Sur on my friend's laptop and then switched back the adaptor and the ssd to my Mac and everything works as expected.So the adapter works as a charm with WD Blue SSN550 but be aware that you may have to do some tricks.

Easy to install

I'm surprised to say, this adapter actually worked as advertised. I was skeptical mostly because I know how Apple likes to lock hardware things down. With that said, it works!I tried this unit in both a MacBook Pro and MacPro. In the MacBook Pro it worked great, the new drive was faster than the stock drive and, of course, was larger. When I moved the same drive into the MacPro, it became dramatically faster! This is obviously a response based on the machine architecture, but it was still very surprising to see. I averaged 120mb/s while restoring from TimeMachine backup. My computer starts up lightening fast and is a joy to use.Highly recommend for users needing a size/speed bump.

Works and fits well. I paired it with a Crucial 1TB SSD. Very easy install.
