Lenovo Y50-70 WiFi to M.2 SSD Replacement

2019-07-17, 18:17 PM

Hi Admins,


I am planning to replace the Internal WiFi Card with Samsung SSD 970 Evo Plus. What are your suggestions? Whether it will fit? Post which whether it will work?




My WiFi Card - Cbt RTL8723BE 1x1BN+BT4 PCIE M.2


I have not yet purchased the M.2. Hence cannot check the whether it will fit or not.


Whereas for the WiFi, I will use external card.

Hi CrazyArjun,


Welcome to the Community Forums.


There would be a big chance that the SSD will not be detected if ever it would even fit.


First is the different orientation of sockets intended for the wlan in contrast to PCIe NVMe storage. 


The PCB of an M.2 module provides a 75-position edge connector; depending on the type of module, certain pin positions are removed to present one or more keying notches. Host-side M.2 connectors (sockets) may populate one or more mating key positions, determining the type of modules accepted by the host; as of April 2014, host-side connectors are available with only one mating key position populated (either B or M).[4][11][16] Furthermore, M.2 sockets keyed for SATA or two PCI Express lanes (PCIe ×2) are referred to as "socket 2 configuration" or "socket 2", while the sockets keyed for four PCI Express lanes (PCIe ×4) are referred to as "socket 3 configuration" or "socket 3"


Another is that most OEM have whitelist that prevents non intended parts to the machine to prevent damage.


Further on the hypothesis, WLAN slot only offers 2 lane against 4lanes offer so definitely not purposeful. If the objective is adding speed for storage transfer, then perhaps it would cost less just replacing current HDD with a SATA 2.5 SSD instead. 


I hope this helps answer your query.
