Memory?

vbimport

#1

How come when you buy any hardware such as flash drives, ipods, etc, the memory is always a little less then specified?

For instance, my 30gig ipod only holds 27.84 gigs? What the space that is missing?


#2

The difference is a result of comparing two different definitions of kilo/Mega/Giga etc.

One definition is based on decimal (SI) prefixes: k=1000, M=1000^2, G=1000^3 …

The other is based on binary prefixes: k=2^10=1024, M=2^20, G=2^30 …

Those who sell drives and disks/discs use decimal prefixes, perhaps in order to claim the highest possible numbers.

Operating systems usually report sizes in binary prefixes, thus reporting lower numbers than for decimal prefixes.

…plus don’t forget that however you count the bytes, some space is also taken up by the disk filing system itself.

I purchased a 1 TB HDD and, it only shows 920 GB so, HDD companies state more HDD space to sell the product. However, PC RAM they are honest about it :smiley:

Unfortunately they don’t tell people or endusers that 1TB is the unformatted capacity and not the true capacity when formatted. Now if the formatted capacaity is 1TB I be more then happy when formatted in windows xp.
