Configuration options for performance

SQL Server provides the ability to affect database engine performance through a number of configuration options at the SQL Server Database Engine level. With Azure SQL Database, Microsoft performs most, but not all, of these optimizations for you.

Options	Description
Disk configuration options	Disk striping and RAID
Data and log file configuration options	Place Data and Log Files on Separate Drives View or Change the Default Locations for Data and Log Files (SQL Server Management Studio)
