    Maybe I'm stuck in a Windows mindset, but it seems like I should be doing some sort of regular maintenance on my Droids software, like defrag it or something. Right now I just regularly delete any apps that I'm not using. I'm not rooted as well.

    Is this type of maintenance necessary?

    It's not necessary, since it doesn't have a mechanical hard drive. You're generally not supposed to defragment any sort of solid state drive.

    Android uses the Linux kernel and is backed by a linux-based file system (Ext 2/3). Ext by default handles the locating and storage of your files by finding the least fragmented sections on the 'disk' (or in our case flash memory). Ext can get fragmented, but it's very rare (you have to be fully maxing out the disk in some really awkward ways -- basically trying to fragment it).

    All in all you should never need to 'defrag' it since the file system keeps things nice and tidy. A FAT-based memory card is a different case, however since memory cards have basically no seek time it shouldn't impact you.

    TLDR: The file system keeps things stored properly, and it's all flash memory anyway -- so you shouldn't need to defragment anything.

    Even in Windows anymore defrag is really kinda pointless. NTFS allocates sectors much more efficiently and doesn't simply use the first available sectors like FAT does. If you're defragging your Windows XP, Vista or 7 filesystems often you're just pointlessly using electricity and decreasing the tme you have until you experience a mechanical failure.

    Couldn't disagree more. I changed my defragging software from Diskeeper to Perfect Disk and the results were immediate with the mountain of digital pics I have accumulated over the years. As ACDSee loads them up into thumbnails it does so very quickly. With Diskeeper (or unfragged disk) it was much slower with hiccups along the way. Not an advertisement for Perfect Disk BTW.

    Defragging flash memory (this is what the Droid uses for storage) is a serious no-no. Flash memory has a finite number of read/write cycles before it wears out (this has to do with electrons leaving permanent channels in the transistors) and defragging would only use up more of these.

    @CarControl. This is a common misconception. It's true that solid state memory has a finite life in terms of read/write cycles - that's also true of disk drives. But the access figures are high enough that it will take decades of use and abuse before a solid state drive will start to fail.

    Unless you're aiming for 50-years plus life, it isn't an issue.

    Microsoft don't agree - they provide an NTFS-specific Disk Defragmenter utility in Windows 7. How useful it is depends how fragmented your disks are.
