A freeware tool turns TRIM on for aftermarket SSDs, and we take a look at how well it works.

In the process of relocating data, deleting stale data, and creating space for new data, they operate on larger blocks.

The trouble is that SSDs and operating systems typically dont have a very communicative relationship.

When you delete a file, the OS marks the space consumed by that data as free, but doesnt tell the drive anything.

Over time, you end up accumulating a lot of available space (according to the operating system) the SSD believes is still needed.

Its only when an OS tells the drive to write to an address containing data that it figures out, Ah, that information must be invalid.

Up until then, those pages are still shuffled around by garbage collection, unnecessarily slowing down the SSD controller and wearing the drives NAND cells prematurely.

When a file is deleted, the operating system sends a TRIM command to the SSD, marking those sectors as invalid data.

At that point, the drive knows not to perform garbage collection on them.

Of course, support for TRIM comes from a few different places.
