Is it advantageous to use Optane Memory if running SSDs in Raid 0?
Not sure of it's real benefits or limitations

m.2 runs through a Pcie lane rather than a Sata lane. so you get a lot more speed.
Will you notice the difference, that's up to you.
I prefer m.2 but anything is better than a 5400rpm hhd.... well maybe not a floppy or cd...

In Raid0 you already see an increase in read/write speed that can be nearly double. An Optane Memory won't make a difference, only on files you use so much that the optane memory loads them automatically. You can have greater read/write speeds if you install a nvme m.2 ssd. Make sure it is a nvme one, for example the m.2 Samsung 860 doesn't really have a improved speed than the standard Samsung 860 sata. The Samsung 960 however is m.2 nvme, communicating through pci-e x4 lanes.

But how am I to believe, just check with Linus:

not worth it... could run into problems with lack of PCIe lanes if you're using a mainstream intel cpu as well.

yes.. but what if you decide to add two I/O cards for example? I have a system that is like this (6700K + m.2 ssd + gtx 1070 + 2x decklink quad2 cards) and sometimes on boot up the computer just doesn't detect one of the decklink cards because it can't decide what to allocate the PCIe lanes too.. theoretically it should be
8x for GPU
4x for m.2 (chipset)
4x for decklink1
4x for decklink2

but in practice that isn't what always happens... so on systems since then when using the consumer intel chips I've gone for SATA SSD RAID-0 instead to save the headache a bit.

if you aren't adding any I/O cards (or just using one) then you should be fine.. or if your motherboard lets you control the lanes.

From my understanding of that post, the m.2's use mobo Pcie lanes not CPU Pcie lanes.

If you run a second m.2 this isn’t the case in my experience.
