Hello, I would like to know if I can use the two DIMM2 adapters to make "RAID 0" with 4 samsung evo of 256 gb M.2, I mean to put two units per DIMM2 adapter and use the Intel x299 chip.
My question is to do "raid 0" _with 4 units m.2 if or if the processor must have enough lanes pci.e and must use the Intel VROC hardware key and the ASUS Hyper M.2 X16 card. In summary, the question is: if I buy an i7-7900x with 44 lanes, can I use the two adapters pci.e DIMM2 to put two M.2 units in each and do "RAID O" with the Intel CHIP x299?

From reading the manual, those M.2 Dimm slots act like normal M.2 slots so it should show up like a M.2 drive similar to other motherboards. However to do hardware raid you will need the VROC key to enable hardware raid (link below). Software raid in window still works but it uses a lot more CPU resources. Page 84 explains setting up raid.

Just like SATA drives. Raiding NVME is pointless besides showing off. A single bigger drive will benefit more and less headache than 4 smaller drives.

+1,.. Raiding NVMe SSDs is pointless.

 

Increasing performance through RAID-0 no longer has the same shine it once had. NVMe SSDs are fast enough to satisfy the most demanding user needs. We've hit a point where RAID-0 run off a chipset gives diminishing returns.

 

Using RAID to increase capacity or add redundancy is another story. Two 256GB drives don't make a lot of sense from a capacity standpoint since one 512GB drive cost less than the pair together. Three drives in RAID-5 are technically viable, but you have to be willing to lose one drive's worth capacity to distributed parity.

 

Aside from those corner cases, NVMe SSDs in RAID just isn't worth the trouble or expense.
