Windows And so the smartphonification of the general purpose computer continues. This time around, though, it might actually be for the better. Microsoft has detailed two new features in Windows 8: refreshing and resetting your computer. Reinstalls will be a thing of the past.

I personally use MyDefrag (formerly JkDefrag), and it does its job well enough although I miss its predecessor's extremely straightforward UI. But that's not what I was referring to in the parent post.

My ext3 and ext4-based Linux installs have never reached a level of fragmentation that forces me to manually defragment them. They stay constantly at something like 1% fragmentation, and apparently it's not a 1% that matters much for overall OS performance.

Yet it doesn't seem like they have to perform any scheduled defragmentation/maintenance tasks, save for the occasional fsck that has become extremely quick in ext4. So I have to wonder what it is on Windows that requires regular defragmentation to be performed for good HDD performance to be achieved.

Either there is something fundamentally wrong in the NTFS spec, or Windows' file management routines are very badly written. I don't know enough about either to conclude. However, since implementation mistakes are relatively easy to fix in software, I'd spontaneously believe that after so many NT releases, if something could be fixed in Windows' code without a breach of software compatibility, it would be fixed by now. So I assume that NTFS is the problem.
