Disk Cache Settings

For I/O-heavy applications like Primavera, go with the writeback option.

• none: Strikes the ideal balance between native-level speed and data integrity by bypassing the host cache entirely, making it the standard pick for production workloads and live migrations.
• writeback: Delivers the fastest performance by using your host's RAM as a temporary buffer, but if the host crashes before those writes are flushed to disk, you could face significant data loss.
• writethrough: Prioritizes rock-solid data integrity by confirming each write only after it's safely on the physical drive, though write speeds take a noticeable hit.

A reboot is needed after applying this setting.
