Is Boot Time Defrag Good?


Today we are seeing is boot time defrag good? defragmentation is unnecessary for the ssd drive because there is no moving parts in it also in HHD it shows a placebo effect.

defragmenting your hard drive it’s a lot like changing the oil in your sedan something everyone has to do regularly but it’s an exciting inconvenient and therefore very easy to put off at least with oil though most people understand the purpose but Windows doesn’t really tell you much about what defragmentation actually is other than some vague statement about how it makes your drives faster so what exactly is it the reason that disk defragmentation is a thing is because of the way a mechanical hard drive stores data think of a hard drive as a really really long sheet of paper when you first install your operating system and put things on it everything is stored in basically a straight line

starting at the top and working your way down but over time of course you’ll start changing or deleting files and adding new ones so suppose one of the files you delete is located closer to the top of the sheet of paper say you don’t want to play minesweeper anymore now you have some free space there that’s right in the middle of a bunch of other data instead of being at the very end like it was when you first started using your hard drive so what happens to

this free space well suppose you put another relatively large file on your hard drive like maybe a filmed speech about how much you love gave in or whatever you’re into but your computer will do is it’ll place part of that large file in that minesweeper free space until it’s filled up and then place the rest of the file elsewhere on your hard drive this is called file fragmentation and it can seriously slow performance because in a mechanical

Drive the platters have to physically spin to allow the drives head to access the files and if a file is broken up into several parts scattered all over your disk it’s naturally going to take longer to bring up whatever it is you’re looking for defragmentation reverses these effects by doing two things one it reassembles any files that have been broken into little pieces and places the files in just one physical location on your disk resulting in faster access to it rearranges most of the free space on your drive into one large continuous chunk

so that your PC won’t try to fragment new files or information and divvy them up into little cubby holes of free space like we did when we were in kindergarten now you might be asking

what if I have an SSD

I heard you’re not supposed to defragment those you would be correct defragmentation doesn’t result in the same performance benefits for SSDs and the reason for this is that since SSDs don’t have any moving parts the PC can access all the data at roughly the same speed regardless of which chip of the SSD is actually holding a particular chunk of a file in fact trying to defragment an SSD can do more harm than good the cells that actually contain data on an SSD can only be written to so many times until they wear out and become completely
