With 64 bit sector numbers we will run into problems too one day......

hmm i hope not, well maybe in a million years or so, ...
in fact with todays technology it would take that long just to write all
those sectors.
interestingly sectors are still quite small, usualy used in clusters of

4.

Colin =^.^=

Yes that is true.
There are plans for larger sector sizes.
But if memory expansion continues the way it has done, say from a 250 kB
floppy (Kaypro II) to a 400 GB harddisk = factor 400 000 x 4 = 1 600 000

x,

in say 1980 to 2005 = 25 years, in 25 years we should have:
1 600 000 x 400 GB = 1 600 x 4 TB = 6 400 TB, so maybe it will happen

sooner

then you think:
6.4 TB = 6.4 x 10^15

2^64 = 1.8 10^19

So around 2050 or so.....
But the big comet comes in 2028 or 2029 anyways :-)

IBM just came with a 700GB tape drive.
So maybe...


I gave up with my 4gb dat tape ages ago,
when I first got it people were amased I could store
several copies of all my disc drives on one tape lol,
now it would take a skipfull of tapes just to stotre 1 realy big drive,
its also started to work out cheaper to just use another HD than a skipfull
of tapes,
700gb is good though, I gues its just about keeping pace.

things dont always keep going up at the same rate, just like house prices
here,
people said they would always be going up, and I should buy sooner than
later,
fortunatly I sold one house and the one I was buying fell through,
then the house prices fell lol.

There must be some molecular limit, I cba to work out how many molecules
there are in a std size HD platter these days.
3D storage is already on the cards I hear, although we have only just got
into vertical bits now wich was on the cards eons ago.

I supose after that limit they will have to move to quantum storage wich
would be infinite - apparently.

Holographic (3D storage?) is available now, but too expensive for us peons.
