TRIM is a command that allows an SSD drive to remove (delete) 1 page at a time instead of a whole folder at a time. In fact it’s slow to deal with writing large chunks of data. With an SSD drive they are different and so it’s much faster to do it 1 page at a time. This is because spinning hard disks deal with huge chunks of data called blocks, which are like a folder, and they can’t deal with anything smaller than a block of data. They spin so fast and the blocks are so big that doing an entire folder at a time is the fastest way to do it. If you think of data as papers in a filing cabinet, to remove an empty page (if you were an old hard drive) you would need to take out an entire folder of papers, then find and remove one page, and then put back the entire folder.
