Hi,

So I'm heavily upgrading my PC when Ryzen comes. This mobo is the one I'm going with:

https://www.google.com/amp/wccftech.com/amd-ryzen-asus-crosshair-vi-hero-motherboard/amp/

My question is this: I have two identical (mushkin Reactor 1TB) SSD's and I get that it's really not much benefit to put two SSD's in RAID0 over Sata 3, as they easily saturate the 600 MB/s bandwidth that Sata 3 maxes out at, but does a card/adaptor exist that you can connect two SSD's to that utilizes the much higher bandwidth that board supports over PCIe? So what I want to do is RAID0 the two 1 TB SSD's over PCIe. The adaptor doesn't necessarily have to have a Hardware RAID, it's fine if it does, as I was thinking windows 10 software RAID is fine. Reasonable cost to performance is preferential, and is it possible to hit faster than sata 3 speeds? Like 800-1000 MB/s at least? (Faster is obviously better) Thank you for your answers!

This is the article: http://www.tomshardware.com/reviews/ssd-raid-benchmark,3485.html

My source is, it doesn't work like that.

RAID 0 is able to achieve double the speed in certain tests because you are pulling separate data from both drives, the bus speed isn't doubled, the system is just getting more data at the same time because its coming from 2 sources. This can be accomplished with your onboard RAID controller, as per the test system. The max bandwidth of SATA 3 is on a per drive basis, not on a whole system basis.

Source? Why can't two SATA 3 600 MB/s be striped for a much higher throughput? Toms' had an article comparing single SSD vs RAID0 SSD's and they (somehow) went far above 600 MB/s with the RAID0 in testing/benchmarks, but the article didn't say how they got that. All drives were sata 3. So they had to be using some sort of adaptor or PCIe card unless there's a magical way to exceed sata 3 bandwidth.

Yes you can easily replicate the results of that test with any Onboard SATA 3 and 2 good drives. That said, read the last page of that test. Great for benchmarks, not so great for real life. Then again at least you already own the drives.

Yeah, I wouldn't be trying this if I didn't already own them. One is already in my desktop, pulled the other from my laptop I already sold and I'm waiting to install it since I'm doing a mobo/CPU/RAM overhaul anyway, I figure I'll just do everything at once.
