Final Thoughts

ASRock's Ultra Quad M.2 Card gives us our first look at Direct to CPU RAID. We came away impressed with the card itself and both ASRock motherboards that we used. This comes as no surprise to us as we exclusively use ASRock motherboards for all our consumer and enterprise SSD testing. We use ASRock motherboards because we get the best performance from ASRock as evidenced by our industry leading SSD benchmark results.

We were pleased with the results we got from our Intel VROC arrays via the Ultra Quad M.2 Card. We liked that we could easily create a bootable Direct to CPU array. Not only did we get 12GB/s sequential performance, we also got 1.2 million random 4K IOPS from our 4-drive array via the ASRock Ultra Quad M.2 Card. And that was real RAID not phony JBOD add the individual SSD IOPS together nonsense.

AMD RAIDXpert is another story. RAIDXpert is not a fitting name for AMD's RAID technology because it suggests something good. It does deliver great sequential performance, but that's the only thing it does. We got 1.2 million 4K random IOPS from VROC and only 250K 4K random IOPS from "RAIDXpert" with the exact same SSDs and Ultra Quad M.2 Direct to CPU card.


This isn't even platform problem for AMD, X399 can deliver the goods in a big way. The problem is solely that "RAIDXpert" is total crap. What else can you call a four drive RAID 0 array with less random performance than one SSD on its own?

We haven't tested other Quad Card M.2 solutions because we didn't even want to test them. The ASRock Ultra Quad M.2 Card is an exception. The design is unique and looks to us like it will deliver the best performance of any Quad Card on the market because of the short traces it offers.

The ASRock Ultra Quad M.2 Card is cost-effective coming in at just $79.99 for a very high-quality piece of hardware with features no one else offers. We really like the idea of being able to add additional power to the card via its six-pin 12V PCIe power connection. This makes Direct to CPU RAID arrays running power-hungry M.2 and U.2 SSDs with M.2 adapters much more feasible.

We feel that ASRock's Ultra Quad M.2 Card is a best in class piece of hardware and it is TweakTown recommended.
