# Bytes And Harddisks.

The Czar
Well, Everyone has been trying to make harddisks with higher capacity, 2 Terrabytes or so ... My friend asked me why no one ever plans to make the bytes smaller. If there is already a topic on this please show me ....

Hi... Didnt get your question properly... What do you mean by 'make the bytes smaller'? Are you trying to ask why they wont reduce the size of a byte???

A byte is made up of 8 bits and that cannot be changed, full stop.

actually expanding hard drive capacity IS shrinking bytes.
physically making them smaller.
but not only. if you look into how the data used to be written on disk 20 years ago and how it is done now, you will spot a huge difference. then it was simple 1010110111011, now the algorithms for data representation on disks are modern physics (ferromagnetic properties, signals etc.) combined with high maths (compression algorithms which few people can really fully understand, i suppose)
basically that's why you can now have a 500GB disk that you can still carry through the door )
they call it TECHNOLOGY

Is it truly impossible to shrink a byte. Why not make a byte = 16bits then that would make a byte smaller Right?

How does redefining the unit have any effect on the storage capacity itself ?

If we change the definition of "byte" from 8 bits to 16 bits, the current 2 gigabyte harddisk will then become a 1 gigabyte harddisk.
The actual storage of the disk remains the same.

It's like hoping to bring distant galaxies into our backyard by redefining the unit of distance.

Well, you could make a byte equal 7 bits, but then you start loosing ASCII codes.
Instead of the full 256, you would only get 128 possible charachters, which besides the obvious compatability problems, would mean that for specialty charachters you would have to use more than one byte. It's not worth it just to save 1/8th of your disk space. Never mind that you would have to redesign the entire computer down to the traces on the motherboard to change it...

That would double the size...

Hard drives ill be past a Terabyte within a year. Vertical storage of the bits in the new 750Gb drives will soon be common, and once perfected, will easily double the space on the average drive.
