Confused about msata (or m2?) internal ssd for Thinkpad Edge e431

2014-03-08, 7:15 AM

I would like to add a mini ssd to my E431 laptop. But I can't figure out if I need to get an M2 NGFF drive, or an msata drive.

 

The e431 has, to my understanding, 2 potential places this could go: The WLAN port, which I understand to be a half height mini pcie port. Its the one located under the main panel, next to the hard drive and motherboard battery.

 

The other port, the one that get's its own panel, is either:

Possibly an m2 port, according to this documentation: http://support.lenovo.com/en_US/product-and-parts/detail.page?DocID=PD027118

 

Or possibly a "full height" msata port, according to this post: http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/problen-with-msata-in-lenovo-thinkpad/td-p/1211038

 

The doc just says M2, it does not specify which size, style of M2, of which I have found at least 4.

According to this page, http://www.mydigitaldiscount.com/m.2-ngff-ssd-compatibility-list.html, the e431 should be using a "2242" 42mm m2, except that model has 2 notches in it ( http://www.mydigitaldiscount.com/mydigitalssd-128gb-super-cache-2-sc2-42mm-sata-iii-6g-m.2-ngff-ssd-with-fnet-hybridisk-software/ ), whereas the port on my e431 only has 1 notch.

 

This one looks like it has the correct number of notches( http://www.amazon.com/Samsung-NGFF-PCIe-Gen2-128GB/dp/B00IT8VTN2/ref=sr_1_13?ie=UTF8&qid=1394262443&sr=8-13&keywords=pcie+2+ngff ), except that it is considerbly longer (either 80mm or 120mm, unsure) It looks like it could maybe fit 80mm tucked in next to the li-on battery?

 


So I am pretty stumped right now! My plan was to remove the wwan card, replace it with an ssd, and then get a new wlan half height pcie card to put in the wlan slot. Any help / clarification would be greatly appreciated!

 

For what its worth, by visual inspection it really does look like an msata port to me.

The E431 definitely has an M.2 SSD slot, not mSATA.  On top of that it's wired for SATA rather than PCIe, so the Samsung XP941 you linked to isn't an option.   (Currently some models of the Sony Vaio Pro 13 is the only laptop I'm aware of that will take the XP941).

 

Now that it's narrowed down to SATA M.2. you then have to consider the length of the drive.  Like you said, it's not specified in the Lenovo docs, which is a shame, but if the illustration is to scale, then it's going to be 42mm long, otherwise known as M.2 2242.    The MydigitalSSD 128GB is a compatible option, even though you're seeing 2 notches on the drive. It still fits and is compatible.  There are larger capacity drives from Crucial and Intel, but they are 80mm long so wont fit.

 

cheers, Rod
