Moving valid data to another block and then erasing the invalid data is a lot of work compared to normal write operations. This movement of valid data to different blocks on the SSD is called write amplification. It must erase the entire block so the task of relocating the valid pages of data is created. Once the SSD starts running out of empty pages, it will begin looking for invalid pages that can be erased, but SSDs cannot erase just an individual page. Having this leftover information means no further information can be written to the block before it is completely erased. It is like a family moving out of the house and having their name removed from the city registry, but leaving all of their belongings behind. This lingering unused data is called invalid data. The reference of the data is removed from the LBA, but the data is not actually erased. When data is deleted from an SSD, the information is not actually deleted. In our analogy, a family would move into an empty house within the city block first. When data is written to the SSD, it is first written to the empty pages.

Related: Don’t wait, upgrade to an OWC SSD today! Think of the LBA as a city registry that knows where everyone lives. SSDs keep track of which pages have information saved on them, and this is called the Logical Block Address (LBA). Let’s think of pages as a house, a block as a city block, and the SSD as the city. These pages make up blocks, which make up the SSD. When data is written to a new SSD, that data is stored in small pieces called “pages”. But before we go further into what TRIM is and why you do not need to be concerned about enabling it on your OWC SSD, let’s take a closer look at some SSD basics.

There is a way to hack the Mac OS to support TRIM on non-Apple SSDs, and we will get into that later on. Apple added TRIM support in 10.6.8, however Apple does not natively support TRIM on non-Apple SSDs.

Microsoft Windows began to natively support the TRIM command for SSDs in Windows 7. But what if you had an SSD so advanced, with a perfect combination of technologies designed to stay at peak performance and speed throughout its life that you had no need for TRIM? Well, you’d have an OWC Mercury SSD, of course!įirst, we should note that support for TRIM is based on the operating system and the SSD manufacturer. Most manufacturers go out of their way to avoid this by suggesting users run TRIM, a command for cleaning up “garbage” files. If you’ve researched using an SSD before, you may have heard how they can slow down over time.
