[B]Yeah joba, I bought the Viking 512mb and it shows 487.06mb :mad: I guess they just round it off. [/B][/QUOTE]
Here is an excellent explanation I found for this.
Storage is advertised as 1,000 bytes = 1KB. However, computers actually consider 1,024 bytes = 1KB.
Real Storage
8 bits = 1 byte.
1,024 bytes = 1 kilobyte (KB).
1,024 KB = 1 megabyte (MB)
1,024 MB = 1 gigabyte (GB)
1,024 GB = 1 terabyte (TB)
In the marketing world,
1,000 bytes = 1 KB
1,000 KB = 1 MB
1,000 MB = 1 GB
1,000 GB = 1 TB
So, if you do the math:
A storage card advertised as 512MB has the following number of bytes:
512,000,000 bytes
or 500,000 kilobytes
or 488.28 MB
A storage card advertised as 1024MB has the following number of bytes:
512,000,000 bytes
or 1,000,000 kilobytes
or 976.56 MB
A Drive advertised as 100GB has the following number of bytes:
100,000,000,000 bytes.
or 97,656,250 kilobytes
or 95,367 MB
or 93.13 GB
Basically, the bigger the card or drive the more space you are "losing".
.9765 bytes -> kilobytes (KB) a loss of 3% of advertised capacity.
.9536 KB -> Megabytes (MB) a loss of 4.7% of advertised capacity.
.9313 MB -> Gigabytes (GB) a loss of 6.8% of advertised capacity.
.9094 GB -> Terabytes (TB) a loss of 9.1% of advertised capacity.
.8882 TB -> Petabytes (PB) a loss of 11.1% of advertised capacity.
.8674 PB -> Exabytes (EB) a loss of 13.3% of advertised capacity.
.8470 EB -> Zettabytes (ZB) a loss of 15.3% of advertised capacity.
.8272 ZB -> Yottabytes (YB) a loss of 17.3% of advertised capacity.
Leave it to the marketing guys to come up with such a confusing system!!!
