Growing issue that seems over looked.

The 15% disk space free to defragment the drive... Now
this doesn't seem much on a 30gig or less drive, but when
your up to a 50gig or higher that number is just more then
you really want it to be.

20gig/3gig
40gig/6gig
60gig/9gig

So the avg drive now which is 120-180gig in size, thats
around 18gig-27gig of space that needs left free just to
defragment the drive. And drives are only getting larger.

I think the time has come to change how it looks at
requried free space for defragmenting from a percentage to
a flat sum of less then 5gig.

The free space required to defrag is based upon the amount of data contained
on the disk.. the more data that one has on a drive, the more free space
will be needed to sort it all out.. please use common sense before making
statements like this..

Growing issue??? What sheer nonsense.

Different defragmenters require different amounts of free space. The
built-in defragment requires 15-20% in order to effectively defragment.
That is due to the design of it's defrag engine.

It's like comparing fuel economy for cars. Some simply don't go as far on a
gallon of gas as others do

Sorry, but the statement is thought out. Data is still
moved in blocks and clusters of bytes of data ireguardless
of the compacity of the drive. Unless it's moveing data
in megabytes or gigabytes haveing more then 2-5gig is a
waste of free space. But we wont be seeing data moved in
that size of blocks and clusters until compactiys get into
terabytes or thetabytes.

Agreed. However, there are some defragmenters that haven't yet developed
the technology to defragment without having a large amount of free space.
