Disk Cache Settings

If you're running an I/O-intensive application like Primavera, switch to writeback mode.

• none: Strikes an ideal balance between raw performance and data protection by skipping the host cache, which is why it's the go-to setting for production environments and live migrations.
• writeback: Delivers top-notch speed by buffering writes in the host's RAM, but comes with a serious risk—if the host fails before data is flushed to disk, you could lose a lot of information.
• writethrough: Guarantees rock-solid data safety by waiting until each write is physically committed to storage, though this comes at the cost of extremely sluggish write performance.

You'll need to reboot after adjusting this setting.
