There are two ways to take advantage of non-volatile storage (NVDIMM) for SQL Server (Direct access or Block Device storage.). Block storage is what you think of today as disk access. SQL works with the operating system to detect the non-volatile storage devices and leverage them for the tail of the log.

For high resiliency systems, it’s even better to use the “rule of three” and quorum based algorithms. This is why most AWS regions have three availability zones. When there’s three ways to succeed, we still have two ways to succeed when a failure is present, and if data is corrupted, we can tell which of the three is the odd one out.
