Upgrading the SSD on the X1 Carbon


Would it be possible to upgrade the SSD of the X1 carbon to 512 GB, and RAM to 16 GB manually? How hard would that be, if possible?


The SSD of an X1 Carbon can be upgraded to the max of 256GB. 


However, the RAM is built into the motherboard and cannot be upgraded manually.


Here is the parts detail for the system board:

The SSD for the 1st generation Carbon X1 has a proprietary "SFF" interface on it.  So mSATA and M.2 SSD drives will not work.


You're pretty much limited to these drives:


45N8481 2 SD 128GB 3.7mmH SanDisk SF X10-128
45N8483 2 SD 256GB 3.7mmH SanDisk SF X10-256 
Though there are adapters to add an M.2 drive to the SFF slot, I have not used them.

Hi Folks!

Just to end the debate if it is possible to upgrade the 1st Generation of X1 Carbon (Type 3460) here some Fotos. I'm working several month with this 512 GB Samsung 850 msata SSD.

Happy Upgrading!

And of course it's possible to use other msata SSDs from different manufacturers. Essential is just the msata-port an the formfactor.

What happens if a 512 GB SSD is installed? Will the X1 only show usage of 256 GB?

I have an X1 Carbon (20BSCT01WW)  with a 512GB SSD and looking to upgrade to 1TB SSD.  

Is the Lenovo 1TB SSD PCIe TLC OPAL2.0 compatible?

Dear Gents, I have Carbon X1 1st generation. Can I uprgrade to 256GB 1/8 inch factor Kingston SSD disc? I have just 128GB SSD in stock configuration. My product code is 3460. Many thanks for any advice.


Kindest regards

Hi  f_lux, sorry to revive an old thread, but I've read this adapter cauuses the keyboard to bulge up slightly due to it's thickness.  Can you confirm if this is correct?.  Looking to put a 256 msata in my x1c1.  Thanks.
