How to understand the higher Hit ratio in the SmartPartition Feature?

A higher write hit ratio means that if the data to be read is in the cache, the hit data is directly read from the cache and does not need to be read in the hard disk, greatly improving performance. The larger the cache is, the higher the hit ratio is because the large cache can store more data, and more data may be hit.

In the Smartpartition Feature, read and write caches are separated. It's either it or it's independent. Here is the write cache instead of the read caches.

Hello

The higher write hit ratio means that the data written to the cache is found to be written to the same address but not flushed in the cache. In this case, you only need to disk the newly written data.

Thank you very much
