Yup, that was the first thing I noticed - after which I did a facepalm.
I'm having a field day today reading all the reviews.. another gem -
Report abuse?
I have seen some people from US saying internet is so fast there the HDD cannot even store data at that rate ****ers didn't even realise someone else was writing data to there disk and on top of it they say they get 15Mbps and that too FUP and when asked about FUP says they dont have anything like that in US
Although I do know that storage is always 5-10% lower than what is advertised, I don't really know why.
Its always the case with many of the ITians around. They seldom know anything apart from their day-to-day work. Either a person have to know and experiment his pc to even understand most of the comcepts or he has to be a pc gamer. A gamer will come across issues and will try learning something.
For OS 1GB = 1024MB but for Manufacturers 1GB = 1000MB and hence one get ~93% of advertised.
1000 is actually about 97.5% of 1024 so by that standard a 32GB disk should have an actual capacity of 31GB.
While you're correct in the 7% difference, would like to know how you're arriving at it.
kilobyte: 1024(actual) over 1000(manufacturer)
Which is 2.4% more
Megabyte 1024^2 = 1048 576 over 1000 000
Which is 4.86% more (rounded up)
Gigabyte 1024^3 = 1073 741 824 over 1000 000 000
Which is 7.37% more
Terabyte 1024^4 = 1099 511 627 776
Which is 9.95% more
because the 1024 is not just looking at MB-->GB conversion.
For HDD manufacturers, 1 GB = 1000 x 1000 x 1000 Bytes (1GB = 1000 MB, 1 MB = 1000 KB, 1 KB = 1000 B)
For OS, 1 GB = 1024 x 1024 x 1024 (1 GB = 1024 MB, 1 MB = 1024 KB, 1 KB = 1024 B).
For conversion, you have 1 GB(Manufacturer) = 1/(1.024)*(1.024)*(1.024) ~= 0.93 GB(OS) = 7% difference.
having to explain the above math in TE under that thread heading is a big irony, isn't it !!
yeah saw that.
