and what's the deal with hard drives I mean you don't drive anywhere in them
0:05
the hardest thing about them is you buy a th000 gigaby drive put it in your
0:09
computer and you got 931 GB I mean what
0:12
were they shaving in there now I'm sure you guys have seen this before and the
0:16
discrepancy is caused by the fact that there are actually two different ways of
0:21
representing amounts of data decimal or base 10 is the more conventional way of
0:26
representing these numbers but with the Advent of modern Computing bin or base 2
0:31
has sprung up now back when data sizes were much smaller an approximate
0:35
equivalency was drawn between a decimal
0:39
kilobyte that is a th000 bytes and a
0:43
binary Kibby BTE which is
0:46
1,24 bytes sure why not it's all good
0:51
well in their defense the difference was only a couple perc so it didn't matter
0:57
this led to many cases of the incorrect
1:00
use of prefixes but if this has been going on for years why are we suddenly
1:05
noticing it now well customers never really cared when their 16 megabyte
1:09
thumb drives showed up as 15 megabytes in change you chocked it up to
1:13
inefficiencies in the formatting or rounding errors but check out this chart
1:18
right here this shows how much smaller your drive will be if the manufacturer
1:23
is calculating in decimal and the software is calculating in binary the
1:28
difference becomes greater gater and greater as capacities continue to
1:33
increase to make matters worse your hard
1:36
drive is manufactured and reported in decimal capacities but many operating
1:42
systems report the capacity in decimal but are actually calculating it in
1:47
binary and what that means is that that one tbte drive that Jerry Linus was
1:53
talking about at the beginning actually is exactly what it says it is it's 1,000
1:58
GB but it's being reported as
2:02
931 GB and I think we can all agree that
2:06
1,000 GB does not equal 931 gbes so
2:12
there have been product returns thanks for that there have even been lawsuits
2:16
about this but the reality of it is there's not much you can do about it and
2:21
once you look into it you'll find there are many discrepancies some where you're
2:24
getting less than you thought some like computer memory where you're actually
2:28
getting more than you thought you were this contrast sharply with audible.com
2:32
where you get exactly what you thought you were going to get in fact head over
2:36
to audible.com tequi right now you can get yourself a free audio book I listen
2:41
to them when I'm falling asleep these headphones are great they actually stay
2:44
in while I'm sleeping so it acts as noise cancellation for me as well and
2:49
right now I am trying the first Twilight book which I can tell you guys so far is
2:54
definitely helping me fall asleep but if you're not into Twilight don't worry
2:58
there's thousands of other options on audible.com and the first one is free it
3:03
always is so head over to audible.com
