Which option is a method for ensuring data integrity during write operations?

The appropriate method for ensuring data integrity during write operations involves how data is handled before it is officially saved. Enabling write caching allows the system to store data temporarily in a cache before writing it to the storage device. This can enhance performance since write operations can be batched and executed more efficiently.

However, write caching must be managed carefully. If the power goes out or there’s a system failure before the cached data is written, the data may be lost. To mitigate this risk, many systems use battery-backed cache or implement other safety measures to ensure that any data in the cache is reliably written to the disk.

The alternative methods presented — disabling write caching, using a solid-state drive, and formatting the storage device — do not primarily focus on the integrity of data during write operations. Disabling write caching could potentially decrease performance without directly improving integrity. Using a solid-state drive improves speed and durability but isn't inherently a method for ensuring data integrity during write operations. Formatting the storage device pertains to preparing a drive for use, not ensuring data integrity during the writing process.
