How to Check if TRIM is enabled and Working on your SSD in Windows 11/10

Basically, data in SSDs is written on something called Pages. And 128 pages make it one data block. Now, for an SSD to write into a block, the entire block must be empty. Even when there is one page with valid data (out of 128 pages), the new data cannot be added to that block unless the entire block is free.TRIM feature tells the OS about the Pages in a specific block that can be discarded. This helps in efficiently managing the storage in SSDs and thus increasing its speed and performance.

In Windows 10, the TRIM feature is enabled by default. However, some third-party utilities can disable it. If you need to cross-check and see if TRIM is enabled or not, read along. In this article, we have listed out fixes that can verify if TRIM is enabled and working on your SSDs.
