    What's the bottom line on this idea of over-provisioning??

    I have an 80 GB SSD with a single C partition covering the entire drive. Windows shows it as 74.5 GB total capacity.

    I take that to mean that I have 5.5 GB of unallocated space available for "over-provisioning".

    Who is to say that is not enough unallocated space? If I need more, how much more and how did you arrive at that number?

    Does the need for additional over-provisioning unallocated space apply to ALL SSDs? Only certain SSDs? Which? With which controllers?

    More clarification on these points requested.
    Ignatz, You are going too scientifically about that. I would play it by ear. A little more or a little less - the difference will be marginal.

    Intel 320 series as you and I have don't need over provisioning for GC/Garbage collection.

    Install the Intel SSD Toolbox and run manual TRIM command once a week and you are good to go.
    Thanks, Hoppy.

    I assume you refer to "Intel SSD Optimizer" from the toolbox, which I have set to run weekly and automatically?

    Windows says my 80 GB drive is 74.5 GB.

    Does the 5.5 GB difference represent unallocated space that Intel has set aside for over-provisioning?

    Or does it represent the well-known approximately 7% difference between the advertised and usable space found on traditional hard drives?

    Or?

    I'm clearly not clear on exactly how Intel drives are different.

    Well and good, WHS.

    But that begs the question: If I am "playing it by ear", what do I listen for? How would I ever know one way or the other?

    What evidence is there of any benefit whatsoever, if it cannot be quantified?

    The 5.5GB is the built in over provision by Intel.

    Sorry I missed answering that question in your original post.

    On the Intels extra OP isn't really a need since it does not use GC.

    At least from info that I have been able to read in the past.

    You set the TRIM for "Auto" so you should not have any problems.

    That is based on what I understand of the info at this time.

    Are you sure. It happens to be the difference of decimal 80 trillion bytes and binary 80 trillion bytes. I thought it was just to the binary reprensentation of the size versus what it says on the box.

    That does not include the 8GB NAND chip used in conjunction with the controller. That is seperate.

    My 120 is actually 128GB of NAND.

    120GB for storage and one 8GB used in conjunction with the controller circuitry.

    9GB of Freespace leaving 111GB usable.

    If I knew what you were talking about here then I could answer maybe.???

    Aha!!!

    So, by inference, an 80 GB Intel SSD is actually 88 GB?

    The 7% decimal/binary differential does not apply, at least to Intel SSDs?

    Where did this 7% come from?

    I'm not sure what you are refering to with that.

    Just trying to provide what memory serves to the best of my ability.

    I had the specs for all the 320's but can't find them at the moment.
    It had the number of chips etc. on each size.

    Here is a pic of the Intel 320 80GB. More pictures here> http://en.expreview.com/2011/03/23/w...b/15569.html/2




    One of the NAND is used with the controller.
