Disk Caching Configuration

For applications with heavy I/O, like Primavera, it is advised to use the writeback setting.

• none: Strikes an ideal balance between native-level speed and data security by circumventing the host cache, making it the go-to option for production and live migration.
• writeback: Provides maximum performance by leveraging the host's RAM as a temporary buffer, but carries a risk of substantial data loss if the host fails prior to disk synchronisation.
• writethrough: Ensures absolute data integrity by only confirming writes after they are committed to physical storage, at the expense of very sluggish write speeds.

A system restart is required after altering this setting.
