Also doesn't help when you are running on virtual / networked hardware. Nothing ensure that what you think is a sector write would actually align properly with the hardware.

The design and guarantees of the virtualized hardware provide that guarantee. I've worked on several such products. They all guarantee atomic sector writes (typically via copy-on-write).
