Resolved Mac Pro 5,1 NVME Speed?

[Fnstrom]

Hello,

I succesfully installed a M.2 Samsung 970 Evo as a boot drive in my Mac Pro 5,1 yesterday.
With much help from tsialex post, thank you very much, very informative and helpful.

But i am alittle nervous if i get the right speed from it, when i do a test with BlackMagic, my results are around 1400 for both read and write, is this to be expected, or is it to low?

I am using APFS

SIncerly yours

Mac Pro has PCIe 2.0 slots, so the maximum possible speed from a NVMe drive installed into a non-switched adapter (switched ones are HighPoint SSD7101A, Amfeltec Squid 3.0 or IOCrest) is around the 1500MB/s mark.

Do you know if for example I use a western digital black series with 3 GB of writing and reading speeds or a blue series with around 2 GB of writing and reading makes any difference for the Mac Pro 5,1?
I already installed A western digital black with 1 TB of storage, but it’s a very expensive drive in my country at least. and compared with The blue series it’s like a 40% less expensive, so I could easily sell my actual drive and save a bit of money.

Thank you.

with the black series I got Around 1.5 GB/s of reading and writing speeds.
Thank you.

It's not just the bandwidth/PCIe version that differentiate one high end blade from a low-end one when installing on a Mac Pro. People look too much at bandwidth and forget that the other specifications are very important too. The controller used by the manufacturer, the size and type of the cache, type of NAND, RAM size, etc…

Btw, several WD Blue models don't work with Mac Pros, see the first post of the sticky thread.

PCIe SSDs - NVMe & AHCI

This is a general info thread for blade SSDs that can be used in the Mac Pro. This is a WikiPost so anyone with the proper credentials may edit it. NVMe SSDs can be used as a boot drive in the MP5,1 and MP6,1 with the latest firmware installed (beginning with version 140.0.0.0.0 for MP5,1 and...
