Are these drives better than normal SSDs?

I am seeing some with write and read exactly the same, while others with insane write/read speeds, are they true or just because of other factors?

They're tidier (no cables) and can be faster, but that's probably down to how much you spend on the drive and the board.
Older ones run off the SATA bus, so you probably wouldn't notice much difference.

I have a 500GB on mine. New board (a year ago). It is very quick. A test showed five times quicker than the 1TB SATA SSD it replace and which is now my Data drive.

What model did you get?

NVMe is much faster than M.2

Now I'm really getting confused

NVMe drives use the PCIe bus, whilst M.2 uses the SATA bus and M.2 is just a form factor and can come in SATA or NVMe versions.
It's the speed of NVMe that's important. SATA III has a max throughput of 600MB/s whilst NVMe can run at 3500MB/s.
When I upgraded my mobo last year, I really should have bought an NVMe instead of the SATA version, but money was tight.

I know it's not SATA but it still says M.2

So invariably I will have to take one of my SSD drives out?

I think M.2 SSD are similar to those that look like WiFi cards in laptops and some desktops motherboards

If it's M.2 NVMe then it should be using one of the PCIE buses (you can buy them in the PCIE form factor).
If your board doesn't support NVMe, then the drive probably won't work.
If you are limited to M.2 SATA then you'll normally lose one of your standard SATA ports, but it depends on the board/chipset.
i.e.
If it supports 8 SATA devices and has 8 SATA ports, you'll lose one, but it might support 8 SATA devices and only has physical connections for 6 (two being reserved for M.2 devices)
Some laptops will have this configuration for 4 SATA devices (one for a standard internal SATA SSD, one for eSATA devices and 2 for internal M.2 SATA upgrades)

Could I use an adapter to add additional nvme drives using a pcie card? Aka hyperkit?

Didn't realise until now that the SATA port the drive took out was my blu ray player

There's always a price to be paid you didn't expect.

I knew it was going to knock out one of them, but forgotten about the bluray because it was one the port where the pcie is used

Can I instead put a separate M.2 NVME in the top slot (top centre) while the other one (bottom right) is occupied?
