Disk Cache Settings

When working with I/O-intensive applications such as Primavera, choose the writeback setting.

• none: This option bypasses the host cache to deliver the best balance between native performance and data safety, making it the standard pick for production environments and live migrations.
• writeback: Delivers peak performance by using the host's RAM as a buffer, but it comes with the risk of significant data loss if the host crashes before syncing to disk.
• writethrough: Ensures top-level data integrity by confirming writes only after they've reached physical storage, though this results in very slow write speeds.

A system reboot is required after you change this setting.
