What are the differences between disk cache and memory cache?

What are the differences between disk cache and memory cache?

Disk cache stores data on a hard drive, while memory cache stores data in RAM. Memory cache is faster but volatile.

When should I use disk cache instead of memory cache?

Use disk cache for larger datasets that don't fit in memory or for data that needs to persist after a reboot.

Are there any performance trade-offs I should be aware of?

Yes, disk cache is slower than memory cache due to read/write speeds of hard drives compared to RAM.

Can I use both types of caches together?

Absolutely! Many systems use both to optimize performance and resource management.
