"Hello everyone, I hope you are all doing very well!
My name is Joe Chengery III and, thanks to Brian, I will be making some, I
hope to be, useful posts on information that you can use to help you build a
better online business. This will include information on computer hardware,
software, resources, Internet marketing, and more.
If you want to find out more about me, please check out my website, http://www.joechengery.com I'm happy to
provide this information to you.
For my first entry, I would like to talk about external hard
drives' "advertised" space versus "real" space - in a future post, I'll mention
why it would be very beneficial to have at least one (if not two or more)
external hard drive(s) in your possession when it comes to your online business,
but for this post, I'd like you to visit the following site:
http://www.newegg.com/Product/ProductReview.aspx?Item=N82E16822186040
Now, I'm NOT suggesting you get that hard drive (though I do personally
like Iomega - I'll mention why in another entry,) but I want you to look at the
bottom review. Notice this reviewer mentions that he's missing 35 gigabytes
(GBs) out of 500, for a total of 465 GBs.
Personally, I don't think this is a good review - what the reviewer says is
true in the sense that that HD is "missing" 35 GBs, BUT, all brands of external
HDs suffer this problem, NOT just Iomega, and his review puts Iomega into a bad
light when it really doesn't deserve that bad light alone. Fortunately, the top
review mentions this.
Now, check out this site:
and the related site it refers to:
There, you will find the reason why there is always less space on your hard
drive than is stated; essentially, it's because the computer considers 1
kilobyte to be 1024 bytes, NOT 1,000 bytes as 1 kilobyte means by definition.
Therefore, it takes a few more bytes to make that kilobyte, and as a result,
the "real" storage space of the drive is less than the "advertised" storage
space of the drive.
Thanks to the commenter "derkmerkin" on the Digg page listed above, we know
that the advertised space of 1,000,000,000 bytes (also known as 100 GB) is
actually 931,000,000 bytes (also known as 93.1 GB.) Knowing this fact, we can
use that to create a conversion factor to help us determine the real space on
our external hard drives:
100 GB advertised space
------------------------------------- = 1.074114 conversion
factor
93.1 GB real space
Now we can use that conversion factor and the advertised space to determine
how much real space we get on our external hard drives:
250 GB Hard Drives:
250 GB advertised space
------------------------------------- = 232.749969 GB (I believe the
computer recognizes it as 232 GB, even though you'd normally round up the
1.074114 conversion factor number to 233 GB; I
know my Iomega 250GB hard drive shows 232 GB of real storage
space.)
500 GB Hard Drives:
500 GB advertised space
------------------------------------- = 465.499938 GB (465 GB)
1.074114 conversion factor
750 GB Hard Drives:
750 GB advertised space
-------------------------------------- = 698.249906 GB (698 GB)
1.074114 conversion factor
1,000 GB (a.k.a. 1 TB) advertised space
---------------------------------------------------------- = 930.999875
GB (931 GB - this one is close enough for the computer to recognize it as 931
1.074114 conversion
factor GB.)
You can use that conversion factor to determine how much real space you'll
actually get from your external hard drives, no matter what the advertised space
is. As you can see, you lose anywhere from around 18 GB of storage space on a
250GB hard drive to up to 69 GB of storage space on a 1TB hard drive. And like
I said earlier, this is true of ALL external hard drives, not just Iomega.
Hopefully, you find this helpful!
Take care and have a great day!
Sincerely,
Joe Chengery III"
