And of course we discovered this at around the same time that these AHCI based SSDs started to become rare…yup.
The only problem here is that the Mac Pro requires an AHCI based SSD to be able to start up, despite most machines of similar age being able to use NVMe based SSDs.
Interestingly, a Chinese company called SinTech produced an adaptor that would adapt the Apple specific pinouts to standard M2 2280 type SSDs. To the point where I had to move both my iTunes library and my Photos to NAS based storage. I’m lucky enough to have one of the faster versions, but it was still a 256GB part, and I was constantly running out of space. Early versions had around 800MB/s transfer, but soon after launch these went to a version that could transfer ~1500MB/s. In fact the only thing that I can remember is that the internal SSDs basically doubled in speed very early on. First some background- the ‘trash can’ Mac Pro from 2013 has not been upgraded much over the years.
