* I/O Crest SI-PEX40129 controller card
* Slot 2
* Two m.2 970 Pro 512MB
* Format RAID/0 HFS boot drive
* 2010 cMP 5,1/12 core 3.46 GHz,
* Boot ROM 140
* High Sierra 10.13.6(17G5019)

Read/Write speeds are only 380/390MBs and should be in the 2000MBs. Any idea what I did wrong? I also tried a single 970EVO 1TB and ran AJA with same low speed results.

Had this same set up in a High Point 7101A with warp speeds in the 5000/6000MBs range.

Thanks!

Would be helpful to install DriveDx and post screenshots of the report. Also include firmware version(s) for blade(s).

The I/O Crest SI-PEX40129 controller card has a 16 lane electrical connection
The board uses an Asmedia 8x PCIe 3.0 PLX chipset, splitting the 8x connection across 2 4x m.2 slots.
In the cMP, the Asmedia chipset runs at 8x, PCIe 2.0,
8 lanes of PCIe 2.0 can deliver a maximum transfer speed of around 3000 MB/s.


The Highpoint SSD-7101 controller card has a 16 lane electrical connection
The board uses an Broadcom 16x PCIe 3.0 PLX chipset, splitting the 16x connection across 4 4x m.2 slots.
In the cMP, the Broadcom chipset runs at 16x, PCIe 2.0
16 lanes of PCIe 2.0 can deliver a maximum transfer speed of around 6000 MB/s.

Your slow speeds sounds wrong and I agree that your system is running toooo slow.

Have you tried the drives one at a time before you built the raid?
Have you tried to rebuild the raid to see if that corrects the issue?
What block size are you running at? I've tried multiple configurations with the Highpoint SSD 7101a, and never experienced a slowdown like you brought up.
Have you run disk utility / first aid?

I did try a 970EVO 1tb before I set up the RAID/0 and seen similar low speed.
I did reformat and used APFS instead of HFS, again in Raid/0, same problem.
Block size (chunk size?) Was set at 128mb.

For whatever reason I did not run First Aid, I will be back in town today and will try that and post results.
Thank you!

Installed a new 970EVO 1TB m.2 after formatting it through my iMac (HFS) and still same slow speeds.
Also ran First Aid on the RAID/0 config with no change in speed...

Sorry...

This is a CCC cloned 970EVO made from the RAID drive~

[doublepost=1553043930][/doublepost]The actual RAID/0 (2x970PRO 512GB) drives are in my High Point 7101A card, but seeing the same low speeds no matter which m.2(s) I install in the I/O Crest.

Been having bad luck last few months with bad electronics!?? My first High Point 7101A died after 30 days of use, got a replacement through Amazon. Thought I'd try this card do to lack of faith in HPT and would be happy with almost warp speed that this card would provide, but....

The replacement 7101A is back to being my boot RAID/0 and doing great, still kinda worried, but really feel I got a bad first card as this one behaves differently. I have thought that maybe it is my cMP killing these cards, but just don't believe that at this point. I have worked on computers and build electronics for last 30 years, I know the 'Laws" of safe handling etc, so can't blame myself either, though I gladly would if I was the problem...

Gonna return the I/O Crest for refund and move forward.

Thank you guys for the help!!

Do not believe High Sierra required permissions for full disk access for CCC, but double check in Menu > Carbon Copy Cloner to see if permissions need to be granted. Believe this is a new change only in Mojave and can prevent a true clone from completing properly.

CCC has issues with APFS / Mojave / NVMe.

It's an apple bug, CCC just aggravates it.

It happens with other disk apps as well. It's an Apple bug.

The issue only happens on NVMe. SATA / SATA Express is not effected.

Not every system experiences the issue, its based on the loading of the pcie bus.
