Pro tip: Defragmenting only works on spinning drives because it puts the data nearer to the spindle so seek times are shorter. Solid-state drives wear out faster if you defragment them, since every write involves a little bit of damage.

I was about to throw hands, but then I learned something new about how SSDs store data in pre-argument research. My poor SSDs. I've been killing them.

No you didn‘t. All somewhat current operating systems do not defrag SSDs, they just run TRIM and it does not kill them.

Most modern OSeses do defragmentation on the fly and you don't really need to do it anymore.

Which makes me sad because I have so many memories of watching a disk defragmenter do its thing from my childhood.

I loved watching disk defragmenter doing it‘s job as a kid. I miss it too!

Here's a little game I made because I missed it too. https://dbeta.com/games/webdefragger/

It's just Paint behind it, isn't it?

I'm guessing you were making a joke, but the real answer is it is a Godot tile map.

That was super cool.

Thanks. It was a silly toy, but it scratched an itch, and was good for at least one chuckle.

Random reads are still slower than sequential in SSD. try torrenting for a year on SSD, then benchmark then defragment then benchmark. it will be very measureable difference. you may need some linux filesystem like XFS as im not sure if there is a way to defrag SSDs in windows.

That's because the drive was written to its limits; the defrag runs a TRIM command that safely releases and resets empty sectors. Random reads and sequential reads /on clean drives that are regularly TRIMmed/ are within random variance of each other.

Source: ran large scale data collection for a data centre when SSDs were relatively new to the company so focused a lot on it, plus lots of data from various sectors since.
