Hi all. I know there is a thread for SSD and Mac Pro, but it appears to be closed for reply.

So here is my simplified question, after reading through other Mac Pro (Pre 2012) SSD threads.

Bottom line, what is the best SSD PCIe solution for a 3.1 Mac Pro ?

My requirements are that the SSD MUST be bootable.

I have surmised that ACHD will boot, HVME will not boot.

I realize that the age of the Mac Pro 3.1 may limit speeds, but anything is faster in a SSD format .. right ?

I just want to get a PCIe SSD adaptor card and a stick of SSD (Or SATA 2.5 SSD drive) , plug it in and reboot.

My Mac Pros are shoe horned using DOSDUDES MacOS Catlina installer solutions, by the way.
Thanks in advance, and thank you to community members who have posted solutions in the past.

Mike.
 
In my 3,1 I bought A 250GB SSUBX AHCI SSD pulled from a 2015 Macbook Pro. I got lucky maybe but I paid just over £30 from memory, plus under £10 for a cheap eBay PCIe adapter. Worked great!

You have to create a script to enable PCIe 2.0 speeds on boot (otherwise it stays on PCIe 1.0 speeds) using PCItools - there are guides online - but it worked very well. After some research it seemed the most straightforward solution - using NVMe required creating a fusion drive, or injecting something into the Bootrom etc
