Maybe I should take a look on Aliexpress, the price I quoted earlier is around half of the next cheapest I've seen in the last month on ebay and after that that its several hundred a pair, which is just ridiculous
soo i guess that the m.2 pcie ssd is not bootable either?
My T7500 is booting from an nMVe ssd with a little jiggery pokerey and the assistance of a crappy old usb stick I found down the side of the sofa and a decent NVMe card from overclockers. It did mean a fresh install of windows 10 though and once I've finished playing around and building it, I will put the tiny little usb stick in one of the internal ports out of harms way. At the moment its round the back hidden between the cat5 cable and the usb keyboard cable. I'm sure I have a one of those indestructible old IBM ones somewhere but I'm buggered if I can find it.
Anyway assuming you have a pci-e card to mount the ssd and your machine will boot from an external usb then the method I I used should work. But it does require a clean install of windows. The method can be found here:-

The meat of the method is about half-way down page one but there is useful clarification if needed between around pages 17 to 23 or so. Don't read all the way through from page 1 to 17 because the stuff in-between happened before the middle of page 1, which was edited and tidied up towards the end of the thread (if that makes sense!!).
As you can see the WD black ssd on the left is pretty good at streaming stuff but not so clever at random writes and even worse at random reads. Perhaps I should have gone with Samsung who at least supply proper drivers rather than relying on native windows support.
I just remembered that I left the bios set to prioritise pci-i/o maybe that's what's killing the small packets of random stuff.

Well I solved my stupid little press F1 to boot problem, like a pillock I hadn't unchecked sata-0 in the list of drives......
I turned off the pcie-i/o priority and also numa support and lost a couple hundred Mb/s on the sequential reads & writes without making much difference elsewhere.
