Advantages disadvantages & RAID and how to assign Qosmio G30 speed

Hello.

I heard that the RAID configuration can increase or not the speed... If someone more expert can explain to me how it works?

1.) first of all what is RAID (explain in words that an ignorant in the calculation as I can uderstand)

(2.) what is the difference between raid 0 or raid 1 and how it affects the computer?

(3.) what are the advantages/disadvantages to choose between this two settings?

Hello

I m not a guru RAID ;) but I used Qosmio G20 with and without a permit to RAID technology and I have not noticed the disadvantages of speed.

I see that you are a beginner and so I will try to explain the RAID feature very easily ;)
What is RAID? RAID (Redundant Array of Independent Disks) allows to save data.

The RAID reflected the content of the first HARD drive to the second HARD drive. This means that all the files (depending on the RAID settings) that are stored on the HDD1 is also stored on HDD2. If the HDD1 will damage, you will be able to recover everything from the HDD2 unit.

The two s of HARD drive can be used with mirror RAID-1 or RAID-0 stripping
When you use RAID-1, data is stored twice (once on each of the hard disks) so if there are problems with one of the hard drives, the other HARD disk can be used to retrieve the data.
But you can use only two hard drives as a single HARD drive. (2 disks hard = 1 HDD)

When you use RAID 0 (stripping) met by the operating system size is two times more!
Using RAID-0 configuration, all data on both disks will be lost, even if only one of the two disks fails!

I think that the RAID is very useful because it safes the contents of HARD drive!
Of course, if you use the mirroring option, you can only use the a HDD available!
But you are on the site course ;)

  • Connection of the loudspeakers and headphones together on Qosmio G30

    My question is, if it is possible to use two different audio out on Qosmio G30. It has two connectors, but seems to be linked together. I want to use my Qosmio with virtual DJ, one audio channel speakers and one for the preparation of music (for headphones). I want to have music on the speakers and headphones to better mix.

    Is this possible, or should I buy an external sound card? Is it inside the map two-channel audio or not?
    Thank you

    Hello

    I'm sure that something like this is not possible. On two ports, you will have the sound of some. Music production you can not choose which port should be used for his outgoing.

  • Fan on Qosmio G30 speed

    My laptop is Qosmio G30-126.
    How can I know the speed of the fan?

    I tried a few soft with sensor hw monitor & fan speed, but it's not watch everything think about the temperature of the CPU just fan speed?
    Where is the problem and what can do?

    Hi vip78,
    If no 3rd party software can detect the speed of the fan due to "unknown chipset" there are two options or even more...
    -Ask your software manufacturer to implement the chipset used, takes long, if it will happen
    -test other software like mb5 maybe it can detect this value

    generally said: If a software cannot detect the value of the speed of the fan
    - either's it the chipset not implemented in your favorite software
    - or the value is not readable cause there is no interface that gives all the values read

    It is only important that the bios gives the operating system of information on the 'heat' - status...

    pls go powersaver options, of course you will get no end of information ventilation speed, but who cares if your system is working properly!

    check mb5, make sure that you have the latest version!

    Good luck

    Hello

    I assume that your RAID settings are set to mirroring (RAID-1) and not to the stripping (RAID-0)

    The RAID may change in the BIOS on the 3rd page.
    Please check this box.

    But note; If you would change the RAID settings you would lose all of the data stored on the HARD drive.

    PS: See you the user manual. There is useful information on the RAID and how to use it.

  • Qosmio G30: How to add the driver RAID without floppy drive?

    I'll put win xp tomorrow, as far as I can remember I will be asked to insert a floppy with additional RAID/SCSI drivers - I guess I need some drivers for XP see my RAID stripe.

    I was able to download 'raid-drv-qog20-xp - 1380.zip', but I'm afraid to look if my laptop has a floppy drive... How can I add the driver did not have a floppy drive?

    Hello

    Maybe a stupid comment, but if you can buy Qosmio G30 I presume that you can also get a used floppy disk. I did this a few times with Vista and Qosmio G30 and it works well.

    Check eBay. You will get the drive used for a few euros. Otherway tries to create CDs and if the RAID drive must travel to ODD, I didn't try because I have a FDD, but you can test it on your Qosmio.

  • Qosmio G30-126: how simultaneously connect analog TV and TV satellite

    Hi, I have a Qosmio G30-126 and you have a problem with receiving simultaneous TV analog (by TV-in the port of integrated TV tuner) and satellite satellite set - top box (by AV-in ports).

    I can't program Windows Media Center for analog TV (but not satellite STB) per port, TV antenna and it works perfectly.
    I can't program Windows Media Center for digital satellite STB (but no TV analog) channels by AV-in port and it works perfectly.
    But I can't program Windows Media Center for the two TV analog I satellite STB, because during programming WMC forces me to choose between analog satellite or cable or SATELLITE box and does not allow me to choose two signal sources.

    For me, it's a big problem, because I have cable (analog) TV and satellite STB with digital channels. And I want to watch all the channels on my Qosmio.
    Could someone help me?

    >... because during the WMC program forces me to choose between analog satellite or cable or SATELLITE box and does not allow me to choose two signal sources.
    I think that in this statement you answered your question. I got Qosmio G30 a long time ago, and I also know that WMC can't handle with two sources of signals at the same time.
    To confirm that contact Microsoft and ask them. I mean that they have designed WMC and know how it works exactly.

    Toshiba has to provide suitable equipment (TV tuner) to provide the TV option on this laptop.

  • Qosmio G30-145: WinXP and RAID driver - no response

    I did everything that is needed for the installation of windows xp for Qosmio G30-145.

    Installation process is as a result: as in http://support.toshiba-tro.de/kb0/TSB56012H0001R01.htm and that worked, but during the installation of windows has started, you will be asked once more (first time I did format and second time that I did ' t format HARD drive): "INSERT THE DISK LABELLED"TOSHIBA RAID DRIVER"in the A: drive... "Press on enter when ready '- but no reaction... SOLUTION!

    Thanks in advance.

    Hello

    According to the Toshiba page suggested when installing Windows using to partition or format the HARD drive, the RAID driver is deleted in the process. This causes the shot the next time that the machine start-up.
    To avoid this, perform a partitioning and formatting before you run the manual installation of Windows.
    This behavior is not displayed during the installation of Windows XP with SP2 integrated

    Well, perhaps, you need a CD OS Win SP2 integrated?

    But why you do not use the recovery CD Toshiba delivered?
    On this CD, all drivers are preinstalled and you only need to install the OS from the recovery CD. All should work properly.

    PS: Just for the record: in the BIOS, you should find an option to disable (or change) the RAID.

    Well you do almost everything bad that could be hurt.

    Here is the code that works to insert data into your table (the procedure is not even necessary).

    declare
    p_sl_num NUMBER := 1001;
    p_description VARCHAR2(50) := 'Testing Val1';
    inval1 test_type1 := test_type1();
    inval2 test_type2 := test_type2();
    begin
    inval1.extend();
    inval1(1) := test_object1('testx1', 'testx2', 'testx3');
    inval2.extend();
    inval2(1) := test_object2('testy1', 'testy2', 'testy3');
    
    INSERT INTO test_object_tpe
    (
    sl_num,
    description,
    main_val1,
    main_val2
    )
    VALUES
    (p_sl_num, p_description, inval1, inval2);
    commit;
    end;
    /
    

    See example 5-15 making reference to an element of nested Table Chapter 5 using PL/SQL collections and records in the PL/SQL doc
    http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/Collections.htm#CJABEBEA

    1. you don't even have the procedure because it is a simple INSERTION in the table you can do directly (see my above code)

    inval1(1).val1 := 'testx1';
    

    Since you have not yet created all the elements, there is no element 1 "inval1". You need EXTEND the collection to add an element

    inval1.extend();
    

    And then, there is an empty element, but "inval1" is a container for objects of type 'test_object1' not for scalars as "val1", "val2", and "val3".
    If you can not do

    inval1(1).val1 := 'testx1';
    

    You must create an instance of 'test_object1 '.

    inval1(1) := test_object1('testx1', 'testx2', 'testx3');
    

    And so on for the other collection

    You don't need the procedure (as my code example shows), but once you fill in the variables correctly it will work.
