Why this difference in speed?

I have the Sandisk Ultra 480 g, why am I burst speeds of 350 MB and 300 MB on average during its 550 MB advertised? I used HDTACH and crystalmark to the bench it. I use a port SATA3, what gives? Thank you

What is the MB you have? I can't find the exact part that you number provided

http://www.gigabyte.com/products/product-page.aspx?pid=4139#SP

If this map looks like so he has 2 different SATA 6 GB chipsets. One is Marvell and the other is not listed in the specifications. You can try the connected both SSD and see who gets the best speed. The Council has also SATA 3 Gb ports so make sure that you are not connected to one of those.

With regard to the pilots to check the MB manufacturers website and see if there are drivers updated, you can try. If the MB has a chipset intel use intel RST AHCI driver. It has the best performance. If the Committee does not have a chipset intel, you will need to use that provides the MB website or the Microsoft driver.

  • Why this difference in query count

    Hello friends,

    running the following query say
    (1) SELECT table_name, num_rows, OWNER OF ALL_TABLES where table_name! = 'KEY_IDS' AND TABLE_NAME NOT LIKE '% BKP %' AND TABLE_NAME NOT LIKE ' % $% ' AND OWNER = 'KUMAR '.

    output:
    TABLE_NAME, NUM_ROWS OWNER
    ADDL_INFO_VALUE_LANG 4457845 KUMAR


    But when I run the query as

    (2) select count (*) KUMAR. ADDL_INFO_VALUE_LANG;

    NUM_ROWS is above all an approximate count

    And you can set the value of NUM_ROWS using package DBMS_STATS (set_table_stats)

  • Why are my download speeds so slow with flag and windows 7. My dell inspiron becomes 10-13 mb

    Pavilion dm1

    REF ly133av

    [Redacted] SN

    Windows 7 operating system

    This Pavilion is brand new and only get like . 2 Mbps of speedtest.net. The download speed is normal, but the dwnload speed is terrible. Now, I still have my old computer sitting here and it is on the same network WIFI get 10 to 15 Mbps of speedtest. It's a dell inspiron with windows vista. This must be a matter of hardware/software. I saw many posts to ask this question but I havnt seen the answers. Please tell me you can help...



    -Ray

    All,

    I have this SAME problem.  I just bought my m6 Pavilion three days previously and immediately noticed that the download speed is very slow.  In addition, a lot of things people recommend this site do take into account that the laptops are brand new, the parameters are already factory installation and things are not running in the background whenever we try to download.  And just like the original - poster I have my old laptop awkward, almost dead here and it's the things download 5 times faster than my new laptop.

    Also, I found another post online from a user in HP Pavilion, who bought a new laptop and this is the slow download.

    So taking all this into account, a PERSON LOGIC CAN CONSLUDE THAT THE PROBLEM IS WITH the computer PORTABLE PAVILION.  Yes, is there an employee HP mans this site who can lift this problem and come back with the official HP answer to why this problem occurs?  I will definiately go online and noted the low ratings sites flag if I don't get an adequate response.

  • Remote Desktop. Why the differences?

    In this case I use Remote Desktop to connect a system from Vista Home Premium to Windows XP Professional on a local network.  Still, it establishes a connection, but can behave in 3 different ways:

    1. the session starts and works very well.  After entering the password (I ask the password), it goes directly on the desktop of the remote PC

    2. the session begins, then I am taken to the login screen of the normal remote PC (what you expect to see if you were working on this PC).  When you enter the password, it then goes to the desktop.

    3. I get the blah "can not load your profile...". ", where Windows will load a temporary profile that takes you back office.  Logging and lumbering back to still seems to work, i.e. log on normally.

    So, no show stopping issues, but why?  Certainly why the difference between 1 and 2?  Thoguh that you arrive at the same place, with 2, you get also present with all the other user accounts on this computer.  For my part, it is not a constraint, but what happens if I don't want to have other possibilities of connection presented?  Remote Desktop Client indicates the account to Log On with, so why present all others?  On the question of the profile, there are a lot of intel available, but I have yet to find the cause in my configuration.  It's exhausting rather than as a problem, but I would be very happy to eliminate this behavior.

    Create a new profile as a test to see if your profile is the source of the problems.

    See "basic troubleshooting: a new profile:

    There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

    If this new profile works then you can transfer files from the old profile to the new profile, but make sure not to copy corrupted files.
