    Is there any value in running defrag utilities with an SSD? It seems to me the re-writing will simply reduce the life of the SSD and do virtually nothing in terms of making it any faster. Am I correct?

    I would agree - the same applies to USB Flash drives...

    I would not defrag an SSD. BTW, here is an interesting MSDN Engineering blog on Windows 7 and SSDs.

    This piece on SevenForums is interesting as well.

    Engineering....and...interesting....hmmmm.

    Ya, no defragging...there are no moving parts to optimize for so access times are equal wherever the data is, and each read/write is one less read/write in the life of an SSD.

    Defragmenting will actually slow down your drives read/write speeds considerably more over time than not defragmenting at all, and thus eating into your total MTTF and it's performance.
    If you really wanted to get anal about drive performance and longevity I would seriously curtail all non essential background operating system read/write processess to a bare minimum.

    Invest a little time and energy in a well thought out BACKUP regimen and you will have minimal down time, and headache.

    Build your own system; get everything you want and nothing you don't.

    Woody's column mentioned that a 'feature' with Windows 7 is an automatic defrag scheduled weekly.

    I checked my SS HD install and found it and disabled it (has been running for eight months)

    Windows 7 is not supposed to schedule a defrag if it detects an SSD. Does your system also have a traditional HD?

    Another reason there is no need to fragment an SSD drive is that defragging benefits mechanical drives because it reduces the time needed for the head to travel and read what's been requested. Since SSD has no moving parts, the principle behind defragging doesn't really apply.

    Definitely do NOT defrag SSDs. It is akin to defragging your SDRam. Not only is it unnecessary, but it will severely reduce its life.

    With Windows 7, any defragging is a waste of time, even for conventional HDDs.
