What are the benefits of using a write-through cache?

A write-through cache ensures that data is written to both the cache and the underlying storage simultaneously. This provides data consistency and reliability.

How does it compare to a write-back cache?

Unlike write-back caches, which only write data to the cache and defer writing to storage, write-through caches write data immediately, reducing the risk of data loss.

Are there any performance drawbacks?

Yes, write-through caches can introduce latency since every write operation involves both the cache and the storage. However, they enhance data integrity.

In what scenarios is a write-through cache preferred?

Write-through caches are preferred in applications where data consistency is critical, such as financial systems or real-time data processing.

Can you give an example of a system that uses write-through caching?

Sure! Many database systems and web applications use write-through caching to ensure that user data is always up-to-date and consistent.
