how do you get a mac pro over 5 gbs read and 6s gb write

[Andy goode]

i have an old mac pro 2012 can you get speed of 20 or even 40 gbs out of this with a thunder bolt bootable drive, and a sonnet thunderbolt pci e card. or are you better.
buying a thunderbolt 3 enclosure for graphics card plus another 16x slot.

Thanks a lot Andy

Hi Andy- the Mac pro forum is tucked away under desktops. Here’s a link.

@maflynn. Mike, maybe we can get this thread moved?

With an external thunderbolt 3 drive and an array of SSDs you’re still looking at achieving around 2800MB/s speeds. That’s pretty much the max with Thunderbolt 3.
I don’t think your 2012 model has Thunderbolt 3 though?

Why are you even bothering with external TB bootables on a 2012?

Throw a PCIe drive in it and call it a day. I think NVMe drives are working reliably on these now, and you need a $10 adapter to let you put one in one of the PCIe slots.

They are. In fact this reply is being written on exactly that

I'm still running Snow Leopard as my main OS on my 5,1, and I've not investigated how it plays with NVMe drives.

I can tell you that booting off a "BX" AHCI drive from a Mac Pro 6,1, SL seems almost like it reads my mind with how fast it is.

As much as I'd love to do that on mine (at least on one of the other drives) I can't, I have a GTX 780 Ti in it which won't work on SL. And eventually I'll upgrade it to some Radeon down the line I'm sure.

I have however booted my Mac Pro 3,1 (currently runs Mojave) which is an 8-core model with 20GB of ram, into Leopard. It has the original GPU (Radeon HD 2600 XT) because the 780 that was in it moved to the 5,1 when I acquired it. That's how I found out intel macs will boot off an APM partitioned disk.. I booted it off my "PPC FireWire drive" that has Tiger and Leopard bootable installers as well as full updated installs.

I've tried booting my 5,1 into an older OS but it just KP's. I expect it's because of the GPU.

What does "BX" refer to? I've not come across that before.

According to [http://www.macvidcards.com/drivers.html], the 780 Ti requires at least 10.9.2 and the Nvidia web driver. You could try booting even older OSes after depriving them of all Nvidia-related kexts. I did that to boot Leopard on a 2010 11in MacBook Air for kicks.

You can also run Tiger on that, you just have to install the drivers for the 2600 XT. Should run faster than greased lightning.
