What are the benefits of write-back caching?

What are the benefits of write-back caching?

Write-back caching improves performance by allowing data to be written to the cache first, reducing latency.

How does it differ from write-through caching?

In write-through caching, data is written to both the cache and the main storage simultaneously, which can slow down performance.

Are there any risks associated with write-back caching?

Yes, if the system crashes before data is written back to the main storage, you could lose the cached data.

When should I use write-back caching?

It's best used in scenarios where speed is critical and data loss can be tolerated, like in temporary data storage.

Can you give examples of applications that benefit from it?

Sure! Databases, web servers, and file systems often use write-back caching to enhance performance.
