Dual M.2 PCIe x8 Card? - Page 3

I don't have windows on that box so I never tested it in windows, but my understanding is that the Intel RSTe driver can combine the 2 drives via software raid. Maybe coupling this with a Z170 board allows you to boot from it. This makes me curious if the P3608 would have better performance with a Z170 motherboard...

from what I have read it works a lot better with the Z170 and can boot it in a raid 0 so suppose to be real fast.. just what I have read. have not bought it yet as it seems to really be more advance that the other hardware that is out there now!!

Has anyone found a PCIE card that has 2x M.2 slots that can have a RAID 0?

I imagine that we'll be able to use something like an LSI card with multiple SFF-8643 connectors, that will then allow us to connect to either U.2 drives, or use a U.2 to M.2 type 3 adapter (allowing us to a SM950 pro on a U.2 cable.

The only thing I found was a website referencing 2x pcie cards and a software raid 0.....

And you're not going to for a while. Samsung is likely using us as Guinea pigs to test out the bleeding edge consumer ssds with these m.2 cards that blow everything else out of the water.

Forget the consumer market right now. The server/database market is where you're going to have to look. Find an LSI controller that supports the newer 2.5" Intel NVMe SSDs that have that U.2 connector. Then you're going to need to use an adapter that has female M.2 socket and a male U.2 port. So that the cables that you'd normally use to connect to the Intel NVMe drives can connect to the Sm951 drives.

Whichever LSI controller (doesn't have to be LSI, that's just what I'm most familiar with) supports this hardware, will have an option on the website for either IR (hW Raid) or IT (sw raid/hba) firmware.

We have the hardware available to us already, just not on some Asus RoG all-in-one card that looks neat under a blacklight.

The look doesn't bother me. I am just tired of these over priced cards that are RAID O SSDs but the modules are built into the card and no way to upgrade except buying a newer/larger card.

I think I have found some PCIE cards with 2x M.2 slots but you would have to RAID 0 via software.

I am running an ASUS Rampage III Formula, so my mb doesn't support booting NVMe and I am out of slots for adding a 2nd Kingston HyperX Predator with my SLI setup.

Here's an adapter like I was referring to.
http://www.microsatacables.com/m2-to-u2-sff8639-pcie-x4-gen-3-adapter-sff-937-4xgen3


Then you can look at some of the cables here. They are SFF-8643 to SFF-8639.

The on something like this. Not sure if this supports it.

Or maybe you can get nutty, attach four of them and saturate PCIe 3.0 x8

Quad adapter. Yes.

I'm not finding any information about connecting an NVMe SSD to a SFF-8639 on an LSI controller running IT firmware.
