this is kind of a random video so we thought we'd shoot it in kind of a random location I'm actually just

00:00:05.560 --> 00:00:12.160
lounging on the balcony outside my office my desk is on the other side of

00:00:09.200 --> 00:00:17.000
this wall so this balcony oversees the warehouse operations here at NC anyway I

00:00:14.960 --> 00:00:21.279
recently uploaded a video to my other channel where we took the cameraman's

00:00:18.960 --> 00:00:26.560
computer and we upgraded it with an SSD featuring trim and Windows 7 so I got a

00:00:24.279 --> 00:00:31.400
few messages asking me what exactly is trim and why did you emphasize so many

00:00:29.480 --> 00:00:35.440
times that that was important and that it was a key feature of Windows 7 well

00:00:33.559 --> 00:00:41.120
first of all Windows 7 is the only operating system right now that does

00:00:37.600 --> 00:00:42.600
feature trim support so there put that

00:00:41.120 --> 00:00:46.800
in your pipe and smoke it that's why it's important but that doesn't actually

00:00:44.760 --> 00:00:54.079
answer the question the question is what does trim do so here's what trim does I

00:00:49.719 --> 00:00:56.199
devised this um example trim is kind of

00:00:54.079 --> 00:01:00.800
like the insert key because normally with any SSD drive the performance is

00:00:58.760 --> 00:01:05.400
actually going to degrade as soon as you take that fresh never

00:01:02.879 --> 00:01:11.360
written flash memory and write over it once every time you try to write it's

00:01:08.560 --> 00:01:15.960
like this so even after you delete a file in clear space if you want to

00:01:13.439 --> 00:01:21.920
rewrite that H you actually have to delete it first which takes up one cycle

00:01:19.080 --> 00:01:26.840
and then you have to write to it after so it takes a lot longer what trim does

00:01:24.560 --> 00:01:30.560
is it's a way of the operating system telling your drive whenever you delete a

00:01:28.799 --> 00:01:35.479
file immediately hey that bit isn't there anymore so you

00:01:33.640 --> 00:01:39.079
can just write right over that so it clears it out right away so it's kind of

00:01:37.600 --> 00:01:45.119
like the insert key if I press the insert key and you know I want to write

00:01:43.520 --> 00:01:51.159
something over this well it helps if I type correctly

00:01:48.159 --> 00:01:54.000
then what it does is it enables you to

00:01:51.159 --> 00:01:59.079
write data without first removing it and it really increases the speed and the

00:01:56.079 --> 00:02:01.119
performance of your SSD especially over

00:01:59.079 --> 00:02:04.960
time now there are other Solutions like garbage collection but trim really is

00:02:02.960 --> 00:02:09.599
the most elegant solution because all you do is pop it into your system and

00:02:07.880 --> 00:02:13.200
forget about it keeps your SSD running in tiptop shape
