so how much eactly IS a petabyte?Vampiric Rouge said:
Ku-sama said:1,024TB i believe
To put that into perspective, mega is 1,024 times kilo, giga is 1,024 times mega, tera is 1,024 times giga and peta is 1,024 times tera
HD manufacturers say that to make it easy for people to understand it. The fact it that its all based on 2^x and thats why its 1024...MasterEVC said:Actually.
1GB is 1000MB according to HD manufacturers
And to Windows, 1GB = 1024MB, which is why when you buy a 250GB HD and only get 233GB.
The way Windows reads it and the way the manufacturers label it are different things.

The loss of hard drive space is due to the fact that drive manufacturers consider 1KB = 1000bytes, while Windows correctly identifies it as 1024bytes. Doing the math:Vampiric Rouge said:The loss of HD space from 250 to 233 is due to formating it you need room for the directory (FAT, NTFS, ect) (I might be wrong but I beleave this is why.)
ceewi1 said:True, but don't forget, that about 20 years ago, a 10MB hard drive was standard. Now, it's not that uncommon to have 1TB (100,000 times the size). 20 years ago, people would have laughed if you said you could use that much space, and yet some people do. 1PB is only 1000 times the current storage capacity, so in that sense, in another 20 years, it may not seem so enormous. Now granted it's portable storage, and it's always dangerous to predict future trends in this way, but my point is that disk capacities do expand rapidly over the years. Comparing a 1.44MB floppy to a 4.7GB DVD or 30GB Blu-ray disc, also gives an idea of how capacity can expand.
