Best SSD for WWAN slot in x270? (M.2 NGFF)

I would like to add an SSD to the WWAN slot in my x270. I have read around that the format is M.2 NGFF 22*42mm. This KingSpan seems to be the cheapest option I can find. A similar KingSpec on Amazon. The 2nd link shows the CrystalDiskMark scores, and they are way down on my current main SSD in the x270. Are these cheap SSD drives worth it? Trust worthy? Is there a better / faster option that isn't going to break the bank? As much advice as you have is appreciated.

From the documents, that's a SATA slot.  ~ 500MB/sec is the best it can support.

I bought a Transcend 128GB MTS400 2240 M.2 for my X250 and it works great. The Transcend SSD Scope software lets you easily clone the disk (f needed - a clean install is better) and speeds are good, I'm getting almost the full advertised 560MB/s read and 160MB/s write.


Worth paying a little extra for an SSD backed up by a company that has a UK office and a decent warranty. 

I do not work for Lenovo, I only provide suggestions based on my personal experience and willingness to help others as a volunteer.
