Apple I bought a brand new iMac on Tuesday. I'm pretty sure this will come as a surprise to some, so I figured I might as well offer some background information about this choice - maybe it'll help other people who are also pondering what to buy as their next computer.

This is honestly such a deep, complex subject that everyone could argue the living hell out of it and no one would ever agree on a conclusion. ;) There are just too many factors involved, and whether you want to hear it or not, the OS involved does make a difference.

I did a quick fsck on my / and /home partitions for the hell of it earlier just to get fragmentation data, and quite honestly, I am amazed at what I saw; it completely backed up what I said, 100%. It was shocking, considering the cringe-worthy state of my system's partitioning. It's in desperate need of re-partitioning, and technically I'm doing a lot of things extremely inefficiently and just downright WRONG, yet far fewer fragments were reported than PerfectDisk would typically report in much better circumstances. And the biggest culprits? Exactly what I expected according to filefrag: three VirtualBox disk images.

And BTW, the reason I focused on data fragmentation is because in my experience it tends to have a far more devastating effect than a bunch of little files scattered all over a drive. That is, assuming you're running an OS and file system combination that is prone to fragmentation in the first place... luckily, in that case there are some excellent tools to keep the fragments under control.

Not to mention, with the general explosion of the data densities of hard drives that has been going on over the years, even if the rotational speeds do not increase a newer drive will still probably read the same amount of data as an older drive, even faster.

The bottom line is that hard drives are wicked fast these days. And with partitioning, it's easily possible to separate your boot files (/boot), main system (/), programs (/usr), and personal files (/home) and keep them all together to minimize seeking between files... but honestly, in my experience you don't even have to go that far, because I've found (for example) Windows XP running practically exactly the same on a 15GB partition at the beginning of the disk as it did on a 60GB partition spanning the entire drive. The only condition? That the number of file fragments are kept to a minimum.

I will just say that I still stand by what I said and will leave it at that.
