As a user who has previously installed an M.2 SATA 2242 512GB SSD on a Lenovo T470, I was curious to know if it's possible to install an additional SSD with the WWAN slot on the Lenovo ThinkPad T495.
I contacted Lenovo's customer service and they informed me that adding an SSD to the WWAN slot is not possible. However, after searching online, I found that some users have successfully installed SSDs in their laptops using BIOS updates or workarounds.
The issue lies in the fact that the M2 WWAN slot on the T495 uses a different keying system than the standard M2 SATA slots. This means that an SSD designed for a standard M2 SATA slot may not fit physically into the WWAN slot, regardless of its compatibility with the laptop's BIOS.
In response to my query, @redxps630 shared their experience with installing an M.2 SATA SSD in the M.2 WWAN (wireless) slot on an XPS 8940 laptop. They noted that the WWAN slot requires a separate USB header to communicate with the card, and that most laptops come with WLAN technology built-in.
@CTG_8273 also chimed in, warning users not to ignore the physical fact that MSATA drives will not fit in M2 sockets. They emphasized that the two systems have different keying mechanisms and screw configurations (MSATA uses 2 screws, while M2 uses 1)., while it may be technically possible to install an additional SSD with the WWAN slot on the Lenovo ThinkPad T495, users should be aware of the physical limitations and potential compatibility issues. It's essential to research thoroughly before attempting any installations, and to consult the laptop's documentation or manufacturer support for guidance.
Key Takeaways:
- The M2 WWAN slot on the Lenovo ThinkPad T495 uses a different keying system than standard M2 SATA slots.
- MSATA drives will not fit in M2 sockets due to physical differences (screw configuration, keying mechanisms).
- Users should research thoroughly and consult manufacturer support before attempting any SSD installations.
I hope this information helps users who are considering installing additional storage on their laptops.
