PC / TB3 / RAID - Slow read/write speeds - Troubleshooting and help please!

[Cory Johnn]

Hey all,

I've recently built a new PC for my office, everything is working great. But my speeds are not what they should / advertised to be.


Here is my current build:
Motherboard - X99A-ii
TB3 Card - ASUS ThunderboltEX 3 PCI-E x4 Card
GPU - GTX 1080Ti
SSD - Samsung 960 PRO M.2 PCIe SSD 1TB
Memory - Corsair Vengance LPX D4 64GB
CPU - i7 6800K 3.4GHz 15mb
RAID - Pegasus R8 - 48TB TB3

Here is my issue:
Getting the ASUS TB3 card to work was a nightmare, and came down to specific BIOS settings, but it now works and recognizes the R8 RAID.
I've ran the BlackMagicDesign SpeedTest and got an average of 300MB/s R/W speeds, and have also ran CrystalDisk and achieved the same speeds.

I have cut a 3 minute project in Premiere using 8K Epic-W footage, and can manage at 1/2 res just fine. But once I bring the footage BACK from resolve as Quicktime Uncompressed RGB 10-bit - the timeline is pretty much unplayable.

I have another friend who has a similar setup although, with the X299 Deluxe and i9-7900x 3.30GHz and is getting around 1300MB/s R/W speeds.

My question is, HOW do I get my setup to these speeds+, where does my bottleneck lie?

I seem to be getting USB3.1 speeds on a TB3 setup which is silly.

I don't want to have swap out MOBO / CPU to achieve faster speeds.

I have already spend around 12K Canadian on this setup.

Thoughts?!

Thanks in advance!

Cory

Thunderbolt firmware has been a nightmare. From what I’ve been told from drive makers is intel supplies the basic firmware and then the motherboard makers are in control of updating it. So some manufacturers are better at updating it than others. Which has lead to all kinds of compatibility issues.

If you have a friend with the same board try testing it with theirs. Make sure the bios and all the drivers are updated.
What drives and software are you using? Keep in mind your not going to get tb3 pipeline speeds...it’ll depend on drives, raid setup, software, etc

Not sure if this will help you, but this worked on my X99 deluxe ii with Pegasus2 R6. This guy's Bios settings worked for me.

Also, just to state the obvious, different Raid configurations will have different speeds.

Anyways, hope something in there helps.
