6 4K Sector HDD FAQ | Dell Inc., 2014

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.
