Avoid using operating system or temporary disks for database storage or logging.

Enable read caching on the disk(s) hosting the data files and TempDB.

Do not enable caching on disk(s) hosting the log file.

Stripe multiple Azure data disks to get increased IO throughput.

Format with documented allocation sizes.

I/O Enable database page compression.

Enable instant file initialization for data files.

Limit or disable autogrow on the database.

Disable autoshrink on the database.

Move all databases to data disks, including system databases.

Move SQL Server error log and trace file directories to data disks.
