Disk Cache Settings
For I/O-heavy applications such as Primavera, choose writeback to optimize performance.
- none – By bypassing the host cache, this mode delivers a solid balance between native performance and data safety, making it the go-to for production systems and live migrations.
- writeback – It offers maximum performance by buffering data in the host’s RAM, though if the host crashes before the data reaches disk, you could lose a lot of information.
- writethrough – This mode provides top-notch data integrity by acknowledging writes only once they're safely on the physical storage, but its write speed is painfully slow.
You must reboot the system after modifying this setting.
