What is Disk Fragmentation on Windows and how does it optimize your hard disk?

It’s amazing how not eli5 this sub always is. Especially now when it’s easy to Eli5. 5 year olds can’t read essays lol. I’ll give it a shot
When you write to a hard disk, files are stored in a certain order, like alphabetically. Like a bookshelf. When you remove a book, you leave a gap and the hard drive just starts putting in pages anywhere that they fit. It takes the hard drive longer to find the full book because it needs to go look on every shelf for the pages.
Defragmentation is just kind of ordering the books again
This isn’t so important with SSDs because there’s no seek time, which means, a hard drive has to spin and spin looking at each shelf, but a SSD just goes and gets the thing it wants
