 * Store multiple ServiceControl databases on separate physical disks to prevent multiple instances competing for the same disk resources.
 * Disable disk write caching (read caching can remain enabled) to prevent data corruption if the (virtual) server or disk controller fails. This is a general best practice for databases.
 * [Database paths](/servicecontrol/servicecontrol-instances/configuration.md#embedded-database-servicecontroldbpath) should be located on disks suitable for low latency write operations (e.g. fiber, solid state drives, raid 10), with a recommended IOPS of at least 7500.
+* Use fixed-size (not dynamically expanding virtual) disks
+* Use solid state drives (SSDs) to significantly reduce seek times and increase throughput
