Disk Cache Settings

For IO heavy applications like Primavera, set to writeback.

• none: Provides the best balance of native-level performance and data safety by bypassing the host cache, making it the standard choice for production and live migration.
• writeback: Offers the highest performance by using the host's RAM as a buffer, but risks significant data loss if the host crashes before syncing to disk.
• writethrough: Ensures the maximum data integrity by confirming every write only after it hits physical storage, but suffers from very slow write speeds.

A reboot is required after changing this setting
