ProBook 6360 SSD performance worse b specified by the SSD manufacturer

Hello!

I bought a ProBook 6360 b, LG635EA #UUZ product number, which comes with a 128 GB SSD. I first installed Ubuntu Linux 12.04 and then noticed that the performance of the SSD has been bad. Playback speed is around 260 MB/s, but writing was much too slow to about 36 MB/s. I installed Windows 7 Enterprise 64-bit with Linux now and installed all the drivers from the HP Support site. The software "AS SSD Benchmark" on Windows displays 260 MB/s read speed and 175 MB/s write speed. Clearly the poor write performance must be a Linux question (I have activate the TRIM support).

Did I wonder on this: manufacturer the SSD (Micron) specifies this SSD to reading and writing of 175 Mbps 500 Mbps. The SSD I have is a MTFDDAK128MAM-1j1 Rev. 809 see http://www.micron.com/parts/solid-state-storage/ssd/mtfddak128mam-1j1

Windows 7 seems to reach the full specified writing speed, but Linux and Windows can not reach specified, almost half being as fast playback speed. Am I wrong in thinking I should get 500 MB/s for reading? It is a SATA 3 drive running in AHCI mode, so this should not be the issue. It doesn't seem to be an update of firmware for this particular SSD, and I already day BIOS to the latest version.

Any help or ideas would be appreciated. Thank you!

Hey jlherren,

Drive HARD Tune is a pretty sweet tool. Co-worker colleague he recommended to me. It's a SATA2 drive. Check out the specs on the HP Support page here site: http://goo.gl/Fymnv

If your seeing this speed, the drive is almost positively connected to SATA2.

Hope this helps,

    Hi all that I just had a Probook G1 450, Walker has problems after replacing the HDD with a SSD.

    Windows installed just fine, but as soon as I installed some drivers, mostly related to the media storage to intel and ETC I get a BSOD with the stop 0x0000001E, and I can't solve it.

    Hi Mrstenter,

    In fact, the problem is caused by the HP 3D DriveGuard driver, if you skip the installation when you have an SSD installed, giving no problem. FYI the SSD, I used was a MX1000 Crucial 256 GB. And after I jumped this instalation driver laptop currently works perfectly.

  • What causes the "specified operation cannot be performed when no device in the task.

            using (task NationalInstruments.DAQmx.Task = new NationalInstruments.DAQmx.Task ())
    {
    task. Timing.ConfigureSampleClock ("", 1000, SampleClockActiveEdge.Rising, SampleQuantityMode.FiniteSamples, 2);
    task. DIChannels.CreateChannel ("PXI1Slot6/Port2/Line3", "", ChannelLineGrouping.OneChannelForAllLines);
    task. Triggers.StartTrigger.ConfigureDigitalEdgeTrigger (triggerLine, DigitalEdgeStartTriggerEdge.Rising);

    DigitalSingleChannelReader reader = new DigitalSingleChannelReader (task. Stream);
    drive. ReadSingleSampleSingleLine();
    }

    Why the code above throws an exception DAQmx with message:

    "Specified the operation can only be performed when there are no devices in the task."

    task name: _unnamedTask<2>

    "Status code:-200477"

    There is a device in the task.  I'm trying to PXI1Slot6 (map of IO 6535) to enter the 2 samples off Port 2 line 3.

    Hi CurtisHx

    Thanks for reporting this. I agree that the error message returned by the driver is very unclear and fails to a user of the API provide enough information to determine the cause of the error in the code. In addition, it seems that we don't document the correct order of operations to set up a task well (the best thing we could find was the subject of tasks in NOR-DAQmx , who actually seems to imply that the channel configuration and their calendar can be made in any order). We are producing several bug reports, to fix / improve the following:

    • The error message returned by the driver to the API.

    • The help topic for the tasks in NOR-DAQmx.

    • The documentation of the specific method provided with the NOR-DAQmx .NET API.

    To clarify the error, it seems that 'peripheral' in ' specified operation cannot be performed when no device in the task "is in fact reference to the channels configured in the task. At this point, I'm not sure what "device" can be applied to other entities in the DAQmx driver software, but I'll post at the time where I have an error message created by the development team working on it.

    Best regards,

  • Remove all lines and insert them into Oracle can make performance worse?

    I m working in a project that I need to make a batch update regularly (every 4 months) of excel files. These files have doesn´t excellent key in their ranks.

    The development of a code that deletes all lines and inserts the entire base again is easier than one who checks in all the ranks of its primary key and if necessary update. (sometimes may be a key to 5 columns).

    My question is: if I delete all the rows in the tables of the insert it again, it will cause tablespace fragmentation and in a future loss of performance?

    Is there a way to avoid this?

  • VCB Incompatible device specified for the '1' device support

    I'm trying to use vcbmounter to perform a full backup of a virtual machine. After the snapshot is run, I get the following error:

    I've narrowed the problem to a second disc which I configured on 90% of my virtual machines. The second disc is where I placed the OS swap file. If I move the swap file and remove the second SCSI disk, hey presto, it works.

    VCB does not save the second SCSI disk? Is this something unique to me? Any advice would be helpful. Thanks in advance!

    Your problem is probably have two files vmdk bearing the same name. This happens usually if the second disc is on a different data store. You must rename the second disc with vmkfstools.

  • Is it possible to change the behavior of the URL bar so that it performs a DNS lookup on the entry that is clearly not a website? (I want to search :)

    Chrome, for example, does not perform a DNS lookup if the entry is not a valid Web site, instead, it searches in the default search engine.

    I think that if the bar URL have behaved in a similar way, it would increase by many user experience. I really like Firefox and using it for a few years, but these are things that really annoy me as a developer.

    The one big flaw that I find in the Chrome version of manages the entrances to bar URL is that one cannot add custom Chrome of top level domains, which makes working with top level domain websites internal quite annoying.

    32-bit operating systems are limited to 3 GB, but the performance is similar in Internet/desktop applications every day.

    If you do a lot of creating media (e.g. video coding high definition or music production), 64-bit would be a better option.

  • Sense of "component of this VI connector is not a part of the connector that is specified by the user."

    That means the following message from VI Analyzer: "part of connector of this VI is not a part of the connector that is specified by the user."?

    The VI it references has 4 connections: 2 in. and 2 outputs. He was selected from a template.

    Everywhere where the VI that it references is used is relinked and properly connected.

    While it has been warned?

    As it says, this is just a warning.

    Many programmers standardize on a small selection of models of connector. VI Analyzer will tell you if a different connector pane is used. One of your screws apparently uses a connector part 2 x 2, which is not used very often. (Example (1) it must be changed if you need connectors later, (2) it does not match the gap-type-in and error-out lower terminals, (3) if it is mounted in series with subVIs most popular models, the son will have elbows and things not the line-up, etc..)

    Two choices:

    1. If you are really in love with the part of connector 2 x 2, add it to the configuration of the parser as a reason accepted.

    2. Stick to a more standardized connector component, even if not all the connectors are currently used.

  • Edit event managed by this case in LabVIEW 2013 does not show the specifiers of the event, Event Sources and events on screen resolution 800 x 600

    Edit event managed by this case in LabVIEW 2013 shows not specifiers of the event, Event Sources and events on screen resolution 800 x 600.

    As far as I know, the list of supported resolutions is determined solely by the graphics card. It is possible that one used by the PC supports only 800 x 600 as maximum resolution, even if you plug an external monitor.

    Like Dennis suggested, the recommended option would probably be to develop on another PC and only deploy an executable for the industrial PC. That's what we do with our systems (although not because of this problem, but because it makes sense. There absolutely no need to have the IDE installed in most of our systems).

    Other options:

    1. See if you can get an update of the driver from the manufacturer to solve this problem.
    2. Plug a USB Monitor with its own driver.
    3. Try to hide the taskbar and make the smaller title bar in the hope that the bug manifests.
    4. Try remote access in the PC. I think that some remote access programs allow you to specify custom resolutions that are not affected by the original drivers. Remote Desktop seems to be a likely this option even if it has been awhile since I've used it.
    5. Check the BIOS. I saw at least one industrial PC where there was some settings in the BIOS to control the resolution, but I don't remember the details, and it was quite limited. I think that in this case, you can change the resolution, but then the image does not fill the entire screen.
