Would you trust your precious data to a stick of gum that's masquerading as a hard drive? Errr, maybe. They are a little fragile which is why I also fit a hard drive and move the users folders to the the hard drive on D: . I've not used this brand of M.2 but I did have a Western Digital drop dead in a system and that did have important data on it.
The thing to realise about these is they are the same price as a SATA SSD and 5 times as FAST! That does not mean your computer boots in 6 seconds but it is more responsive. As with any SSD it's how fast it handles the 4k files that determines it's feel after it's booted. NVMe is a format that bypasses a lot of the protocols built in to SATA. SATA is simply the serial version of IDE with the ribbon cables for spinning drives. NVMe realises that this is a new century with new technology so it's not designed to allow for the disk to rotate.
If you have the opportunity to fit one of these then you should. I chose this one as a compromise between price and performance, 2200MB/s but spend more and get 3400MB/s if you feel the need.
