What is the type of HD is compatiable for the the Thinkpad Carbon X1 Gen 3. I am having hard time finding a SSD to fit.
X1 Carbon 3rd Gen (Type 20BS, 20BT) Laptop (ThinkPad) - Type 20BT - Model 20BTS2BV00

A parts lookup for your model shows you have a M2. 2280 SATA slot. It is not a PCI/e 3 x 4 slot.
The Lenovo shipped M.2 is part 04X4440 , a Samsung PM851. Newer part numbers are showing in this list.
To upgrade your device, your specs: M.2 2280 Sata 6GB/s.

I believe that the Gen3 carbon was also available with SM961 SSDs (04x4479 and 04x4480) which are PCIe4 so it appears that those will work also.

PSREF does show:
"Storage: M.2 SSD / PCIe 2.0 x4 or SATA"
The FRUBOM list shows both M.2 2280 PCI/e 2.0 x4 and PCIe 3x4.
Parts lookup on the support page for the users full model name came back with 1 device, the part I showed pictures of from the support page parts lookp. I would assume, depending on model of machine, your M.2 2280 PCI/e support is Gen 2 or Gen 3.
The SM951 made its first appearance at Samsung SSD Global Summit in July 2014 where it was touted to be the first client SSD with NVMe support. Unfortunately, Samsung changed its initial plans and the SM951 as it's known today does not support NVMe, but it still provides an upgrade from PCIe Gen2 to Gen3, which theoretically doubles the available bandwidth. Samsung is tight-lipped about the reasoning behind the decision to dump NVMe support, but from what I understand the current chipsets don't have proper NVMe support by default. It's likely that Samsung's PC OEM partners wanted to stick with known AHCI command set for improved compatibility, so Samsung decided to push the introduction of client NVMe SSD a bit further back.
your PM951 is NOT a Lenovo offered part and was NEVER shipped via Lenovo OEM spec. You can chal·lenge this post and what I report is accurate. Do your homework before you jump on my post.
all respect, kindiss.
