00:00:00.120 --> 00:00:05.640
defragmenting your hard drive it's a lot like changing the oil in your sedan

00:00:03.719 --> 00:00:10.759
something everyone has to do regularly but is unexciting inconvenient and

00:00:08.080 --> 00:00:15.000
therefore very easy to put off at least with oil though most people understand

00:00:12.799 --> 00:00:20.279
the purpose but Windows doesn't really tell you much about what defragmentation

00:00:17.760 --> 00:00:24.720
actually is other than some vague statement about how it makes your drives

00:00:22.160 --> 00:00:28.800
faster so what exactly is it the reason that dis defragmentation is a thing is

00:00:27.039 --> 00:00:34.000
because of the way a mechanical hard drive stores data think of a hard drive

00:00:31.240 --> 00:00:37.760
as a really really long sheet of paper when you first install your operating

00:00:35.719 --> 00:00:41.840
system and put things on it everything is stored in basically a straight line

00:00:40.079 --> 00:00:46.920
starting at the top and working your way down but over time of course you'll

00:00:44.600 --> 00:00:51.480
start changing or deleting files and adding new ones so suppose one of the

00:00:49.280 --> 00:00:55.760
files you delete is located closer to the top of the sheet of paper so you

00:00:53.039 --> 00:00:59.039
don't want to play mind sweeper anymore now you have some free space there

00:00:57.559 --> 00:01:02.559
that's right in the middle of a bunch of other data instead of being at the very

00:01:00.840 --> 00:01:06.600
end like it was when you first started using your hard drive so what happens to

00:01:04.479 --> 00:01:10.640
this free space well suppose you put another relatively large file on your

00:01:08.560 --> 00:01:14.200
hard drive like maybe a filmed speech about how much you love gay Ben or

00:01:12.479 --> 00:01:19.000
whatever you're into what your computer will do is it'll place part of that

00:01:16.320 --> 00:01:23.240
large file in that mind sweeper free space until it's filled up and then

00:01:21.280 --> 00:01:28.119
place the rest of the file Elsewhere on your hard drive this is called file

00:01:25.640 --> 00:01:32.360
fragmentation and it can seriously slow performance because in a mechanical

00:01:30.200 --> 00:01:37.119
Drive the platters have to physically spin to allow the drive's head to access

00:01:35.079 --> 00:01:41.399
the files and if a file is broken up into several parts scattered all over

00:01:39.600 --> 00:01:46.399
your disc it's naturally going to take longer to bring up whatever it is you're

00:01:43.520 --> 00:01:50.840
looking for defragmentation reverses these Effects by doing two things one it

00:01:49.240 --> 00:01:54.719
reassembles any files that have been broken into little pieces and places the

00:01:52.640 --> 00:02:00.200
files in just one physical location on your disc resulting in Faster access two

00:01:58.000 --> 00:02:05.479
it rearranges most of the free space on your drive into one large continuous

00:02:03.119 --> 00:02:09.039
chunk so that your PC won't try to fragment new files or information and

00:02:07.280 --> 00:02:13.000
divy them up into little cubby holes of free space like we did when we were in

00:02:10.680 --> 00:02:16.879
kindergarten now you might be asking but L hold on a second what if I have an SSD

00:02:15.440 --> 00:02:22.360
I heard you're not supposed to defragment those you would be correct uh

00:02:20.360 --> 00:02:26.840
defragmentation doesn't result in the same performance benefits for ssds and

00:02:24.599 --> 00:02:31.560
the reason for this is that since ssds don't have any moving Parts the PC can

00:02:29.440 --> 00:02:37.120
access all the data at roughly the same speed regardless of which chip of the

00:02:34.319 --> 00:02:43.360
SSD is actually holding a particular chunk of a file in fact trying to

00:02:39.239 --> 00:02:45.480
defragment an SSD can do more harm than

00:02:43.360 --> 00:02:50.440
good the cells that actually contain data on an SSD can only be written to so

00:02:48.480 --> 00:02:55.000
many times until they wear out and become completely useless and

00:02:52.840 --> 00:02:59.280
defragmentation uses up a lot of those right Cycles playing digital 15 puzzle

00:02:57.800 --> 00:03:04.640
if you're running Windows 7 or newer though don't fret the OS actually won't even let you defragment any connected

00:03:02.480 --> 00:03:09.000
ssds and will instead give you an option to optimize the SSD what this will do

00:03:07.200 --> 00:03:13.480
instead of defragging is send something called a trim command unlike mechanical

00:03:11.400 --> 00:03:19.000
hard drives on which the data can simply be overwritten the cells on ssds have to

00:03:16.120 --> 00:03:24.040
be erased before new data can be written to them or else you can seriously lose

00:03:20.959 --> 00:03:26.360
performance over time trim erases cells

00:03:24.040 --> 00:03:29.519
with old data that hasn't actually been physically removed from the drive yet

00:03:27.920 --> 00:03:34.239
which I explained in this video by the way ahead of time so the SSD can write

00:03:32.280 --> 00:03:38.200
new information to those cells much more quickly in the future trim is usually

00:03:36.560 --> 00:03:41.640
handled automatically by Windows so you don't need to do much to keep it running

00:03:39.720 --> 00:03:45.480
other than running a trim Checker to ensure it actually is working but if you

00:03:43.959 --> 00:03:50.159
have a mechanical hard drive make sure de fragmentation is running periodically

00:03:47.720 --> 00:03:54.720
otherwise halflife 3 might actually be confirmed by the time the game you're

00:03:52.120 --> 00:04:01.239
playing whatever one it is actually loads speaking of loading I'm sure our

00:03:57.200 --> 00:04:03.959
sponsor is coming soon wait for

00:04:01.239 --> 00:04:08.640
there it is audible.com audible.com has over 150,000 audiobooks that you can

00:04:06.239 --> 00:04:14.280
download and listen to on the train while you're training with earbuds so

00:04:11.200 --> 00:04:15.879
you can block out your train Central HV

00:04:14.280 --> 00:04:19.199
fact unit okay that joke got old but they've got everything from the latest

00:04:17.600 --> 00:04:23.040
popular audio books to Classics like weathering Heights by Emily Bronte

00:04:21.440 --> 00:04:26.520
sometimes the original author even narrates the audio book but in the case

00:04:25.000 --> 00:04:30.080
of today's featured title that would have been a little tricky but what's not

00:04:28.400 --> 00:04:35.000
tricky is becoming a member so you have a new audiobook to listen to every month

00:04:32.600 --> 00:04:39.800
the first one is even free with no obligation so head over to audible.com

00:04:37.240 --> 00:04:42.520
tequ to try it out thanks Audible for supporting our Channel thanks to you the

00:04:41.240 --> 00:04:46.400
viewer for supporting our Channel and you know what thanks to me for

supporting our Channel I always thank you guys and say I couldn't happen

00:04:48.199 --> 00:04:55.000
without all of you but damn it I'm an integral part of this too I mean imagine

00:04:51.680 --> 00:04:55.880
a three-way without the third which is

00:04:55.000 --> 00:05:00.919
just you know what I'm just going to quit while I'm ahead make sure you're subscribed if you aren't already
