performance - How to more efficiently use SSD?

Background:
I am using a standard used laptop which I have upgraded(SSD and RAM) to reduce bottlenecks in performance.

Problem:
The CPU has become the main bottleneck now, but what I have noticed is that even when using very I/O intensive tasks, disk usage rarely exceeds 10% according to Task Manager(I am using Windows 10). I have seen tasks such as the Windows Search Indexer get as high as 50% disk usage, so 10% is not some kind of limitation.

Question:
How can I make more efficient use of the SSD? This includes general tweaks, Windows specific tweaks, anything related to process/thread management, optimizing software, etc.

Regards.
