Above it is a small amount of DRAM, which acts as an instruction and data cache, plus it stores a table of data locations on the drive. The chip in the middle is a processor that manages all the instructions, data flow, encryption, and other algorithms. The sample below is of a relatively old SATA model (Samsung 850 Pro), but even the latest SSDs aren't much different in terms of the components that make up the drive. We've taken apart SSDs before and you'll see that there's not much inside of them. To understand why SSDs don't just delete files when you press the button, we need to take a quick look at how they work. Simple, yes? What actually goes on, though, is quite a bit more complex - read on to find out! Digging into the guts of your SSD But when it does, not only does it free up space on the drive, it helps the SSD perform better and last longer, too. The trimmed data isn't always removed straight away, as a complex process decides exactly when this takes place.

Trim works by periodically erasing blocks of data that are no longer in use. SSD trimming is a process that helps to maintain the performance of a solid-state drive over time. Such good questions all deserve thorough answers, so in this article we'll cover all of that. Have you ever noticed when you go into Windows to optimize your storage drives, it says retrim for SSDs? Just what exactly is getting trimmed and why is it needed? Is it the same as defragmenting or something entirely different? (it is different).
