MBP SSD impending failure
There is an app named DriveDx that can show you if there are problems with the drive. Not that it is 100% full proof but better than nothing.

Also I remember I had issues with Paragon NTFS too (like file system corruption). Microsoft changes NTFS with each release and it is not "open source", so it is not known how compatible Paragon is. I am sure they do their best but it is difficult to be compatible with such closed system as NTFS.
