You wont notice any difference over your SSD. Usually you use M.2 for your operating system. I have an M.2, an SSD and mechanical drive. I have noticed no throughput difference between the M.2 and SATA in anything other than synthetic benchmarks.

There are which confirm this.

I use my M.2 for windows and key apps. SSD for cache and temp folders and everything else is done from either the network attached storage or the local mechanical drive as often the bottleneck is Vegas rather than any drive throughput. In my playback and rendering testing the difference between network vs SSD vs M.2 vs Mechanical is negligible.

It depends on your project. If you do 4K or even 1080 60p mulitcam editing with 4 or more camera angels, a SATA-III drive will be your limiting factor.

When you mention "M.2" you should always be clear whether drive is SATA or PCI Express 3.0 (NVMe).

"Computer bus interfaces provided through the M.2 connector are PCI Express 3.0 (up to four lanes), Serial ATA 3.0, and USB 3.0 (a single logical port for each of the latter two). It is up to the manufacturer of the M.2 host or device to select which interfaces are to be supported, depending on the desired level of host support and device type."

M.2 has a physical layer specification that allows different interfaces. The fastest interface, PCI Express 3.0, will help make some process run faster, multicam as OldSmoke mentioned, uncompressed or high bit rate intermediates, but some process won't benefit at all.

Right, I am looking at the PCI Express

and I have one 4k camera plus 3 regular high def cams

Fast SOURCE drives are important for editing multi-cam 4K.  The target drive does not matter as much unless you are saving to uncompressed…  My new 9900K system has (2) 2TB Intel 660P M.2 for SOURCE video setup in RAID0 on the motherboard. The 2TB 660P's are $180 USD and have fast read speeds and fast write speeds until they are half-full... Connected to the motherboard's fast U.2 connector via an adapter & cable is another 2TB M.2 for TARGET video. A 4th 2TB M.2 is in on a PCIe adapter card where the 1st partition is the OS & the 2nd partition is background music & commonly used video files for effects, etc. For many years I had a 6-drive SATA RAID0 as SOURCE and a 6-drive SATA RAID10 as the TARGET, so file transfer speeds were around 400 Mbs but that setup was hot & power hungry...

Source Video from (2) 2TB M.2 on motherboard in RAID0
Output Video to (1) 2TB M.2 via motherboard U.2 adapter & cable
OS & background music on partition #1 of (1) 2TB M.2 connected via PCIe
Customer work on partition #2. Entire OS drive backed-up nightly...
Copies of recent client work on (4) 8TB SATA hot-swap drives on PCIe RAID10 card

Copy of Work Files, Source & Output Video, OS Images on QNAP 653b NAS
Blackmagic Decklink PCie card for capturing from tape, etc.
(2) internal BR Burners connected via USB 3.0 to SATA adapter
Old Cooler Master CM Stacker ATX case with (13) 5.25" front drive-bays holds & cools everything..

Workstations A, B & C are 4.0ghz Xeon 5660 or I7 980x on Asus P6T6 motherboards.
I do not upgrade until I can get 2X the render speeds for <$1500...
The 9900K (or Threadripper 1950x/2950X) were the first to make this affordable...
Chose the 9900K because Vegas & Photoshop shine with faster core speeds & QSV enabled...
Next upgrade will likely be when PCIe 5.0 is available next year for faster M.2 I/O on PCIe cards...

@TheRhino your 2x 660's in raid 0 can have I suppose sequential read 2x1.8 = 3.6 GB/s of bandwidth which almost can saturate the DMI link at 3.93 GB/s between the CPU and Chipset. Then there is 2 more M.2's connected via pce adapters, either adding to the DMI bottleneck or stealing PCI lanes from the CPU itself if connected together with the videocard (in the latter case it will not add to the DMI bottleneck, but this will drop the number of PCI lanes available for the videcard from 16 to 8 (or 4 depending), effectively reducing the bandwidth of the videocard. A difficult choice right? Or am I wrong?

Bandwidth requirement for uncompressed 4K is about 12 Gbit/s so 1.5 GB/s. For any compressed stream it is lower (magicyuv capable of 90 fps 4K and compression would be 1.5+ so 1GB/s required per stream, this is CPU dependable).

I'd say that SSDs in raid0 is only needed if you are often editing with more than one uncompressed 4K+ stream on more than 1 track. This is also make sense only if every other component of the system is capable of processing the stream in realtime.

So for me it is an easy choice: I would not set the raid0
