m.2 and PCIE SSDs work great.
Benefit is the performance which can reach up to the speed of 4 PCIe Lanes.
Downside is the missing reduandancy and a lot of time it is hard to use them as boot devices.
m.2 compared to single SSD it is always the way I would go.
SSD Raids can get faster than PCIe SSDs and m.2 when you build a system with 8 or more regular SSDs.
m.2 and PCIe SSDs are also limited in size.
With a good 8x or 16x SSD Controller you can easily get 6 or 7 TB of Storage.
I have worked with systems using PCIe SSDs (Intel), m.2 (Samsung) and SSD Raids (PB Servers).
Hope that helps.
