Re: SSD Hard Drive for Carbon X1 Gen 3 20BT

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.

This is a misleading (almost, if we don't mean the number of PCIe lanes).
.
A quote from the x1c gen3 specification:
"Storage: M.2 SSD / PCIe 2.0 x4 or SATA"

...disregarding the MT or MTM.
I have x1c gen3, MT 20BT. The SSD installed is PCIe Samsung SM951.

Re: SSD Hard Drive for Carbon X1 Gen 3 20BT

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. 

 

Sm951:

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.

In SUMMARY,

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.

Re: SSD Hard Drive for Carbon X1 Gen 3 20BT

Hi - Thanks for the details in this posting. It helps a lot, but I am still kinda bummed out that on the parts page it shows a sm951 as a compatible ssd to install in the unit.  i purchased one hoping for a bit of a faster drive but keep getting a boot error 2103 ( i think) and i even called tech support and gave the fru number for the sm951 (512 gb) (4XB0N10300) and was told it was compatible. I don't kbnow if this is a 'samsung' hush hush issue or a lenovo thing or what, because Crucial shows a similar nvme ssd as compatible with the 20bt carbon x1 3rd generation and that ssd also comes up with a 2103 error. 

this is a big mystery to me, as this posting shows a sm951 worked in a 20bt model carbon x1.

https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/Found-a-960GB-SSD-with-AHCI-for-X1-Carbon-3rd...

 

do i need to change bios settings, or install an alternative bios? or is this laptop restricted to a 6Gbps ssd? please help.

if the pm951 isn't compatible, lenovo should make it clear and remove it from the parts list and clearly state that a pcie or nvme ssd won't work in that laptop.

here is the lenovo link - i'm saddened and disappointed!

many thanks

Re: SSD Hard Drive for Carbon X1 Gen 3 20BT

Hi,

 

I don't have one but IIRC the PCIe SSD in the X1C G3 is AHCI, not NVMe.  To make things more confusing - and perhaps explain what's going on - the SM951 came in AHCI and NVMe versions.

 

The base spec says SATA or PCIe but not PCIe/NVMe, and here's a page (chosen at random) that shows both versions of the SM951 - even says "Lenovo" on the AHCI version.
