Z440 M.2 PCIe RAID help

[pcrispy]

We have (4) HP EX920 M.2 1TB PCIe 3.0 x 4 NVMe drives that we would like to put into our Z440 using something like this QNAP QM2-4P-384 controller card in the PCIe3 x8 lane.  QNAP tech support said that they thought it should work since the specs for the drives and controller card match up all around.  They just weren't 100% sure if everything would be good to go with the computer itself recognizing the card/drives, etc, or how to best go about creating them all as one big RAID 0.

Any help or other suggestions would be awesome.

qnap can only support this card on their own products, so it's no supprise they don't have any info/support for 3rd party systems all you can do is try it and see what happens

or you can buy the HP version of the qnap card

I talked to the HP Workstation division on the phone after posting this (required a lengthy online chat first in order to get to the next level) and they obviously pushed their Turbo card, but when they realized that you can't buy it without SSDs already installed then they suggested that the 3rd party might be a better option since we already have the drives.  HP said that it should work no problem.  QNAP obviously is only real familiar with it's use in NAS systems, but the guy did say that it should work fine in a PC and he has talked to other people using it that way.  For just the card, the QNAP is $269 compared to HP's cheapest option being $779.  I may look for some Turbo's that are used to see if I can get a cheaper option, or one with the drives already pulled.

it would have been most helpful if you had posted the details you provided in your second post  as i would have known that it was not nessary for me to post anything since you allready had the nessary information you required

I actually got an alert about your message when I wasn’t on the phone with HP, so the timing was basically simultaneous.  Either way, since neither manufacturer had first hand experience with the setup actually working or not (just that it should) then any additional help would be super helpful.

i'm aware of only 4 other quad raid cards two of which are enterprise (with prices to match) the other two are the Asus and Asrock  quad m.2  SSD consumer cards i'm not sure if these cards require PCIe port bifurcation

Thanks!  I just now looked them up and the ASUS is only $85. Maybe worth a shot for something that cheap just to give it a try.
