Like any other storage device, NVMe SSDs can fail. However, it’s rare for them to fail suddenly. Usually, the SSD will give out a few warning signs, such as slow performance and random disappearance of data, before it completely gives out. The quality of an NVMe SSD will vary across manufacturers, so it’s recommended you only buy them from reputed companies such as Samsung, SK Hynix, WD, Kingston, etc.
