What drive gives max speed for MacPro and is enough (not to pay for those not used by PCIe speeds)

I would like to create topic about increasing Mac Pro 3.1 drive speed.

As all of us know, main disadvantage of MP 3.1 is SATA II speed limit.

My Mac Pro is very slow with FCPX or Premiere (latest versions). I want to upgrade disk subsystem.

After a lot of reading I understand that PCIe SSD adapter gives much more speed than 2xRAID0 SSD on standard bays.

Surely, I need bootable Drive.

What are the limitation of our PCIe lane? (I mean If we buy the fastest SSD's possibe, could we get max speed or it would be limited and there is no reason to buy 1200 mb/s or 1600 mb/s drives?)

Is there are reason to buy M2 drives, instead of SATA III SSDs? As I understand these small SSD's gave better performance.

By the way, I don't want to buy OWC products because of high prices. But I want to buy the best PCIe Sata adapter and drives (or, if after discussion we understand that it gives better performance - then I would buy PCIe with M2 drive).

Is there reason to buy Samsung 950 M2 SSD to mainly use it in Mac Pro 3.1? (Also, in future desktop, when needed)

Also, I want the SSD adapter to include SATAIII ports for additional drives.

P.S. In any case sorry, English is not my native English (Russian is).

I hava a M2 drive ... It's slow in cMP 3,1.
And I downgraded the ram.
A fast SataIII on a PCIe slot would be cheaper ...
It boots ... read/write is just a lot slower than the drive can achive.
Maybe others were more succesfull with the speed, I read some can't get it to boot.

Old thread but the question is still valid...
I use a Kingston HyperX PCIe card as a boot drive in my MacPro3,1, maybe not the fastest but fast enough to make me smile.:D

I got that one on my nMP on TB where it is faster.
But got the samsung that should be faster in my mp 3.1,
and get both 700/700.
The samsung should be the faster card.

Anyway I'm happy for you. :)
