Why disable SuperFetch on ssd, if the RAM is much faster than the ssd?

Directed by Microsoft that SuperFetch and PreFetch must be disabled, if the OS is installed on an ssd, in accordance with article http://support.microsoft.com/kb/2727880. But SuperFetch is used for loading the data components of applications, which were very often used for RAM. Although the ssd is faster that a hard drive is not faster than the RAM. So, I do not understand why Microsoft suggest disabling this feature. The only reason why I want to understand, it's because of a limited RAM. If the RAM is sufficient beyond 6 GB, if we disable SuperFetch, then the boot time and increase the loading time of most used applications. I miss something here?

The other question is about PreFetch. I feel, maybe wrong, it does the same thing with SuperFetch, with one major difference. It loads all the information data on the ssd or hard drive, instead of the RAM, in order to accelerate the launch of applications and time when the OS is installed on a hard drive to boot. If I'm right, let's disable the PreFetch it stores information for one ssd or hdd, while SuperFetch stores data of RAM information, which is much faster and so it must be enabled if there is a sufficient RAM.

I look forward to reading the notice of a Microsoft software engineer.

Hi Leventis,

Prefetch copies frequently accessed files together into a contiguous on the disk area so that they can be located and loaded more quickly. That it takes a lot of old drives to recover data faster.

SuperFetch predict what applications you run next and preload all the necessary data in the memory. She has also done that with startup files. And for all the three days he sends a defragmentation command to the OS drive that will cause problems in the SSD drives.

In traditional hard drives (HDD) data are scattered throughout the disk, so that the operating system for access, it will take more time. It is suggested to perform a disk defragmentation. But storage technology is different in SSD, where, it records the data dynamically and it recovers more quickly. Who will be low down the burden on the RAM and the RAM can be used for uses such as for the opening of the games graphics high-end, etc..

Hope this information is useful.

  • T500 T8700 processor work much faster than on the current of a battery!

    My colleagues and I are having a very annoying problem with our thinkpad t500 (approximately 200 laptops or more). the problem is that the CPU is intel core 2 duo T8700 2.53 ghz works only with 1.6 ghz speed on idle and load the State with alternating current and never jump higher than speed and jumps only to 2.53 ghz speed if and only if the battery is connected to the laptop, the laptop is faster using the battery that is strange indeed.

    My own opinion on this issue, it is that it is a bug in the bios that is the switching in a different way processor modes (processor with power supply ofc should be faster than with battery) I've already updated my bios of the laptop to 3.09 version, but always without success. The serial number of my laptop is "*".

    I hope that fix you this very soon.

    Moderator edit: number masked to prevent improper use.

    Hi mtaher and welcome to the Lenovo user community!

    Connected to a 65W power adapter, the T500 is relies on the battery to power during peak load. If you remove the battery, he's choking back the CPU at a level that the 65W adapter can handle alone. It probably won't happen if you use a 90W Adapter (I don't have anyone around to test - maybe someone can confirm).

    The research community and you will find this discussed many times - that's the behavior designed most of the models.

  • Why disable Superfetch with Windows 7 VDIs?

    According to best practice paper:

    http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1021049

    It says to turn off superfetch in Windows 7.  I would like to question why this is desired behavior.  After all if SuperFetch increases the starting time and the starting time of the physical desktop application, should be with guests as vdi.  The only reasoning I can imagine, it's that extra i/o consumed is too much of a disadvantage to SuperFetch is worth it and it is maybe correct.  If anyone can confirm this?

  • Why Flash cookies are not deleted the first time I'm leaving Firefox?

    I am running XP, Firefox 16.0.1 and Flash Player 11.4.402.287 and have Firefox configured to 'Clear history of Firefox closing', with 'Cookies' (among others) checked "settings to erase history. I also have Flash Player configured to "Block all sites to store information on this computer."

    As I understand it, from Firefox 4 and Flash Player 10.3, have Firefox configured in this way should cause cookies Flash should be deleted out of Firefox. I also understand that even though I have Flash configured as I do, a list of websites that try to plant a cookie Flash is always recorded in the main settings.sol cookie.

    I noticed, however, that this list of empty Flash cookies is not removed the first time I have quit Firefox; on the contrary, the list is deleted after launch and then leaving Firefox again.

    Here is a step-by-step example:

    (1) Control Panel-> Flash Player-> storage tab-> storage Local to Site-> button settings confirm that the list is empty

    (2) output, that manage Flash Player settings

    (3) launch Firefox-> go to http://www.Hulu.com/ and click on a video to start playing

    (4) recovery Control Panel-> Flash Player-> storage-> Local website storage settings... tab button-> make sure that the list indicates http://www.Hulu.com/, 0 bytes, block

    (5) leave the Flash Player Settings Manager

    (6) Firefox exit

    (7) raise Control Panel-> Flash Player-> storage-> storage settings Local to Site-> NOTE THAT THE LIST SHOWS AGAIN http://www.Hulu.com/, 0 bytes, block

    (8) leave the Flash Player Settings Manager

    (9) restart Firefox

    (10) raise Control Panel-> Flash Player-> storage-> storage settings Local to Site-> NOTE THAT THE LIST SHOWS AGAIN http://www.Hulu.com/, 0 bytes, block

    (11) exit the Flash Player Settings Manager

    (12) exit Firefox

    (13) stimulus Control Panel-> Flash Player-> storage-> storage settings Local to Site-> NOTE THAT THE LIST IS now EMPTY

    Once again, my question is - why this list is not emptied the first time around?

    Safe mode disables plugins, I think not, so that you can put those aside for now.

    I suggest disable all non-essential extensions. We all tend to accrue to those who are not really necessary. You can do so here:

    Orange Firefox button or classic menu Tools > Modules > category: Extensions

    If the kernel extensions, you really like the cause of the same problem, then I think you will have to just live with it. Please note that Flash is followed correctly your bet as a block, so I don't think that something is actually stored.

    Hello Beth.

    I must inform you that (as directed by your user agent string), you use Internet Explorer 8 for the moment, not Firefox. I hope that you are aware of this.

    On the toolbar, you sure it's the download which is the problem and not the installation? The toolbar may be browser specific (for example, it can work only on Internet Explorer), so if it is the facility that gives you trouble, you should contact the author of the toolbar for support.

    If it is the download that is problematic, you can have a problem with an extension or plugin that is an obstacle to the normal behavior of your Firefox. Have you tried to disable all add-ons (just to see) to see if Firefox goes back to normal?

  • Why my old emails disappear from the cloud?

    Why my old emails disappear from the cloud?  After only a month or two, they are gone! (and I pay extra each month more space!)

    Hello Unhappywoman,

    Thank you for using communities Support from Apple!

    From your post, I understand that old emails are deleted after a month. This can be due to behaviors of the mailbox defined for your iCloud account.

    The following article explains how to look at these settings. My suspicion is that the section "permanently erase deleted messages when:" is set at one month old.

    Use Mail preferences to set or change options for e-mail accounts , you use mail and to work with messages and mailboxes. Choose Mail > Preferences, and then click a preferences panel for the options:

    • Accounts: Add, remove, and disable your email accounts in mail. Use only the part of the mailbox behaviors to control how the project, junk, sent, and deleted (or "Basket") messages are stored. Advanced pane includes options for messages, attachments and more.

  • Vista, why my cursor jumps around on the screen without reason?

    Vista, why my cursor jumps around on the screen without reason?

    You are using a laptop with a touchscreen?  Chances are good that you accidentally touch the touchpad while typing, and that moves the cursor.  Go to start / Control Panel / mouse and see if there are controls for adjusting the sensitivity of the touchpad or to disable the touchpad while typing.  Go to the web site of the manufacturer of your and download the latest device drivers, firmware, and software for touchpad you and your mouse (if you also have a mouse - you may have to go the manufacturer of the mouse for these drivers, if she did not come with the system).  New updates can offer options that did not exist before like the ones I mentioned.

    This happened to me also and I bought a separate mouse and disabled the touchpad and the problem disappeared - but he had me past for awhile until I finally figured it out by typing differently (with my hands up higher so the Palms do not touch and had no problem).  Even if this isn't the problem, update the drivers, firmware or software can solve the problem on its own.

    If none of the works above, we will need either to run a complete troubleshooting procedures (post back and I'll meet with them) or the touchpad or mouse is defective and must be replaced.  You can discuss these last with the computer manufacturer when you talk to them (if you talk to them).

    I hope this helps.  If you have any questions along the way, come back and I'll do my best to answer.

  • Any ideas why Outlook 2007 "violently" flickers between the windows and window main? How to fix?

    It is not all the time, but when it gets into fashion, sometimes you can close the application yet.  The only thing we can do is to shut down the pc.  The task Mgr will not stop it.

    I can't identify exactly what initiates it.  But usually, I have other applications open (Word or Excel) MS & Firefox, maybe.

    It is an example, when you explore Contacts and open a contact window to edit or review.  You leave Outlook to go to the other application and then you see the fast flicker goes into the taskbar.

    Another example similar to the above, this is when you change a contact window.  Right-click to change something, then display studders and falls in flashing mode.

    Intuitively, I think it has something to do with the display or the video card.  I've done R & are the driver for the card.  The only reason why I think it is that the problem decreases in frequency of appearance, apparently with the largest size of display text.  In addition, I don't think that this has happened after the update of the graphics card (see below)

    FYI...

    Windows 7 64 bit
