Can I replace my 16 GB M.2 SSD with 128GB M.2 SSD?
If yes, Can I make Windows 10 to boot from 128 GB M.2 SSD?

I have a T550 and wouldn't even consider adding an M.2 SSD (and I have a spare one handy).
On the T450 I had two separate M.2 SSD (2240/2242) failures within 30 days of install... failure to boot with "M.2 SSD error" message.
Corrupted the SMART logs on the SSD and only mounted them R/O....
They were NOT used as boot devices either, just regular storage (EXT4) under Linux. Both were new from Amazon, one was a Transcend and theo other a HP LiteOn.
I believe the X250/T450/T550 and maybe others have serious issues with M.2 devices.

Thanks for sharing this,
if the problem is with the interface/chipset, how would 16 GB M.2 would work flawlessly that came inbuilt with the new purchase

I suspect specific firmware versions of some models are OK as supplied with the original machines, and then perhaps only for Windows caching.
However most third-party later installs have firmware issues, two failures of brand new M.2 in 30 days very unusual.

Thanks again for valuable information.
My brother users thinkpad and he often comes across blue dead screen.
Official Lenovo service center said the place where SSD is installed is prone inefficient weight management
And when the laptop is kept on a desk, usually blue screen error does not appear. In case I keep it on my lap, the blue screen error appears frequently.
To resolve this problem, is it a good idea to replace hard drive with normal SATA, and use SSD as storage drive?

I have also heard about the M.2 power issue problem and this seems to affect many T450/550 owners.
I would only use the M.2 as a Windows caching device with Lenovo drivers. In fact this is the only recommended way.
Too many problems otherwise!

Just my expereince, I own t550, with M.2 SSD with Windows 10 installed there.( I have Windows 7 on my main SSD (SATA).)
Computer does not survive whole night when it is on, sometimes when eve 1 hour idle.
It seems like Windows 10 is simply disconnectng power (as wrote above). so it cuts it self from hard drive
I think I dont have any control in power management (bios, windows, elsE), that I can prevent it.
So I just keep preventing my laptop idle for more than 1 hour, or shutting down. Because Sleep does not work properly, I have 50% chance from waking up notebook from sleep that I receive BlueScreen for varsious casues.
I have TS64GMTS400 (Transcend 64 GB)

Under linux Gnome Disk Manager power management can be set I think, and possibly in Windows in Device Manager and right click on the M.2 Drive object? Might be options under one of the M.2 driver tabs to control power.
I gave up with the T450 and T550 with M.2. devices.... something about these machines!

I recently purchased a T550 off craigslist. My intention for it was to run 2 flavors of Linux on it. I replaced the primary 2.5in HDD with a 1TB SSD and installed Fedora. I wanted to put in a MSATA drive in as well as I have done with my T430s, but found that it does not have a standard MSATA connector. After digging around the interwebs for a bit, I was able to find the correct SSD. I ordered it from Amazon, installed it, and it was successfully recognized by the bios, and I was able to install ArchLinux on the SSD with no issues. I've been running it for a couple days now and have had no issues at all with it.
