The date type is Date, and I would like to set the default date to now or today.
When a GUID column is used as a row identifier, using NEWSEQUENTIALID can be faster than using the NEWID function.
This is because the NEWID function causes random activity and uses fewer cached data pages.
Creates a GUID that is greater than any GUID previously generated by this function on a specified computer since Windows was started.
The expression can be a noncomputed column name, constant, function, variable, and any combination of these connected by one or more operators.

On SQL Server, clusters of sequential values can develop when databases (such as contained databases) are moved to other computers. You can use NEWSEQUENTIALID to generate GUIDs to reduce page splits and random IO at the leaf level of indexes.
When using Always On and on SQL Database, clusters of sequential values can develop if the database fails over to a different computer. Each GUID generated by using NEWSEQUENTIALID is unique on that computer.
