9. Is there data integrity risk during sudden power off?
If volatile write cache is disabled:
• 512n and 4kn HDD, there is no data loss during sudden power off.
• Enterprise 512e HDD with NVC and/or MBC/MC feature (see section 5) also does not have
data integrity risk.
• For 512e without NVC or MBC/MC (Client grade HDD), there is a risk of data integrity
during sudden power loss.
If volatile write cache is enabled, then sudden power loss will result in data cache loss regardless
of the HDD format types.
