    The outside of the disk, as well as having the shortest head stroke is also an advantage because speaking scientifically, a disk spins faster at the outside edge. I'm not saying that on a 7200RPM the outside is spinning at 10000 or something. It's hard to explain.

    Think of it like this; Immagine the platter of a HDD. It's flat and circular. Imagine a line drawn from the centre to the outside edge (the radial line). along this like you draw one dot near the inside of the disk and another near the outside. Now imagine how long a line you would het if you were able to stretch out the circle formed by the rotation of this dot.

    Lets pretend that the drive platter spins at 10 RPM and the inside dot's rotational line stretches out to 1". Also imagine the outside edge dot's rotational path stretches out to 10". From this we can then say that in 1 second, if the heads are at the dot 1 position then 1" of platter goes through the heads per second. In the dot 2 position, 10" of platter goes past the head in 1 second.

    If more physical area passes through the head at the outside, then the outside is travelling faster than the inside. Speed = distance/time even with a disk. Don't you just love physics?

    It's less beneficial for an OS to be restricted to the 1st partition because of a few things. First the drive firmware will do its best to make sure the disk is filled from the outside in, meaning only the last bits of data to fill the drive will be at the slow end. Second, you have Boot Defrag, Prefetcher etc in XP, Vista and 7 which will move all the needed files at boot and all program files to the very outside edge of the disk.

    The reason a page file benefits is because the drive firmware over rides the logic of placing things at the edge when doing a lot of little random writes, as if it didn't 4K write performance would be even more horrible than it is now on HDD's. Performance would suffer immensely.
    You set your swapfile to a fixed sized based on the amount of RAM do you do let the sytem manage it? I've been using 1.5 X amount of RAM and setting it to a fixed size. Curious since you're using a partition for your swapfile.

    Setting my WD Black up now and Perfectdisk put the swapfile in the center of that 12Gb partition I made. Which IS the first partition by the way. Arrived in the very cold last night. Suprised the UPS man didn't ring the door bell. Found it when I let the dog out. LOL

    To prevent or lessen fragmentation you guys should be using the same size for Max/Min on your pagefiles

    Agreed, about the min/max I also make my PF 128MB or so because it's not needed as a gamer at least. (some applications like UltimateDefrag do require it on even if a small amount or I'd have it off completely)

    I also use UD to place it (along with the MFT, USN Change Journal, Logfile, etc.) at the beginning of my HD for maximum performance along with my high performance data. (Windows/Games)

    It doesn't matter if like me you're using a seperate partition. Remember, although the page file is seen by Windows Explorer as a big "pagefile.sys" it's really just a container for loads and loads of small writes ie RAM being paged out then back in.

    Fragmentation performance drop on a page file therefore isn't all that great. Definitely set a fixed size if it's on your System partition and you have plenty of space. If however it's on a small drive, letting it grow as needed up to the max of the drive is fine. The page file will also force itself to shrink should a program need to save to disk.

    Optimum configuration for a page file is to have two identical sized page files on two hard drives/non RAID SSD's. This is because from XP upward a certain amount of parallelism was introduced. Sort of like software RAID but just for the page file.


    You can also tidy up any excess fragments the page file may get into by using PageDefrag. It's so good, Microsoft bought it. download it from here: PageDefrag You can choose to defrag on every boot if you wish.

    Above all, the over riding factor is that if you set a reasonable size for the initial page file quantity, it will seldom grow. Mine only ever does when using Photoshop and sometimes HandBrake (H264 encoding). Usually on a 64bit system with 4GB of RAM, the page file isn't heavily used.

    There are many myths about the page file, like having to set 1.5x RAM amount. This isn't true. You may think that one needs enough to page out all installed RAM, but you don't. The more physical RAM you have the less swap space is necessary. Linux has it correct, partitioning a seperate section of the HDD with an optimized file system just for swap space. It will also use every last drop of RAM before paging anything.

    If you use S3 Sleep though, you may need as much as physical ram right? Just checking

    I'm almost certain that S3 doesn't require a page file.

    When in S3 the PC's RAM goes into a mode called "Slow Refresh". This is supported by all DDR2 and DDR3 as well as some DDR RAM. This means that all pages can be kept "alive" with minimal power. As there are no real Memory operations going on, the sticks aren't really drawing any significant current. In total, the standard calls for 5W of power to be used by the motherboard and components. This 5W doesn't include the wattage the PSU will be constantly drawing to maintain its +5VSB for the "Power Good" signal.

    I've used S3 on systems with 8GB of RAM where the (unexperienced) customer has asked the page file be disabled. Unfortunately I can't test it currently as I have no boards that can successfully resume from S3, even at stock.

    Doh!! Of course not, sorry I was sleeping and must have been thinking of the old sleep S1 days when I posted that!

    Guess I need to be sure I am awake before I start making myself look silly :)

    No harm, no foul mate. :thumbsup. S States aren't the simplest things in the world. |Even "On" has an S state for example (S0).
