Dell Precision M4400 and NVME.

Hello, I want to contribute here some information for those who want to dust off or like vintage hardware (like me), this is purely for informational purposes since it is end-of-life hardware and without any support, I bought 2 NVME units with their respective adapters specifically for my M4400 M6400 and T500, I will leave it although it is not possible to put a purely MSATA unit, because it does not recognize it, you can put a modern NVME unit, with a Mini PCI to NVME adapter, but do not expect the transfer speed to be as fast as in modern devices, in fact in the images that I will put you will see that the normal Sata SSD is much faster than an NVME unit.

Something to add is that if you were to place it in the WWAN port. It won't let you put it in properly, you have to cut the adapter a little more with a grinder, and you won't be able to put the screw in for the 2242 size, so I recommend you get a 2230 size unit, which will let you put the little screw in, logically for the 2242, although it won't let you put the grip screw in, since it goes in all the way, you can secure it with black insulating tape or capton tape, whatever you have on hand and it will stay fixed, in the BT port you won't have a size problem with the 2242, it's up to you, and you can even put 2 NVME units inside in the WWAN and BT ports and it will recognize both, in my case I won't put one in the BT port since I like to have 2 wifi cards for emergencies.

Regarding compatibility with older devices, I don't know which brands are compatible and which ones aren't, in theory all NVME 3.0 should support PCI EX 1.0, but I don't know which specific brands, at least you can be sure that in the images the brand that I put supports it.

Obviously this doesn't work as a boot disk, only as a static/data disk that you install and use within windows/linux, the bios won't recognize it in any way, well without further ado here are the images.

P.S.: This is for informational purposes as a legacy for older hardware, I hesitate to answer responses to this post since everything is in the images and finally if you want to do this verify that everything is for mini PCI express, using NVME, do not use ngff or sata/ata variants, it will not work.
