Can anyone else confirm this? I don't know if this is a windows-only

I can confirm that it's only a Windows problem. No UNIX filesystem
that I'm aware of suffers from fragmentation.
What do you mean by suffering? All filesystems fragment files at some
point. When and how differs from filesystem to filesystem. And some
filesystems might be smarter than others in placing the fragments.
To clarify my viewpoint:
To my knowledge, there is no Unix filesystem that _suffers_ from
fragmentation. Specifically, all filessytems have some degree of
fragmentation that occurs, but every Unix filesystem that I am aware of
has built-in mechanisms to mitigate this and prevent it from becoming
a performance issue.
More specifically, this problem was solved on UNIX file systems way back in the
1970's and 1980's. No UNIX file system (including Linux) since then has had
significant fragmentation problems, unless the file system gets close to 100%
full. If you run below 90% full, fragmentation shouldn't ever be a significant
performance problem.
The word "fragmentation" would have dropped from the common parlance if it
weren't for MS Windoz.
