Does upgrading to a larger harddrive increases the speed of your computer?

Hi,
I was wondering if increasing the size of your harddrive is going to speed up your computer?
Thanks,
Brandon

Tough question that depends on several factors. First is how full was your old drive, the closer it comes to capacity the slower that makes your computer. As a general rule of thumb OS X should have a minimum of 10% free disk space to operate OK. Next is the RPM speed of the drive drives, you can buy hard disks that spin at 5,400, 7,200 & 10,000 RPM, the faster the RPM the quicker the input/output. Theoretically if you replace a 7,200 RPM drive with a 10,000 RPM drive that will speed up the input / output.
So if you are replacing a drive that is currently filled to 70% capacity that spins at 7,200 RPM with a larger capacity 7,200 RPM drive then no you probably won't notice any difference in performance. However if you are replacing a drive that is at 90% capacity that spins at 7,200 RPM with a higher capacity 10,000 RPM drive then yes you will probably see some performance increase.
Bottom line, not simple question to answer.
Regards,
Roger

  • How can I increase the speed of LabView computing?

    Dear all,
    I have a problem which I didn`t thought to face.
    My problem is the folowing. I have Implemented some applications in Labview but with my great surprise the program is incredibly slow!
    One of these was just a simple try to produce sinusoidal signal. I simply made a While loop where the sine of the "i" iteration number was calculated and then
    sent to a NI- 6559 DAQ through an USB port and the DAQmx Assistant.
    Well this simple program runs at 300 Hz Maximum. A similar program in C can without problems reach 20000 Hz!
    Now I am asking if Labview is the wrong choice for more than 100 Hz applications and if it is not convenient to shift directly on C language.
    Namely I want to let you know that the apllications I need require a loop speed of at least 800Hz.
    Really I cannot understand why the system is so slow. It cannot be otherwise Labview should be unusable for the large part of the applications.
    Can you suggest me what I am doing wrong, or maximum speed reachable on a normal 3 Ghz Pentium, 1 Gb RAM?
    Best regards
    Principiant
    Solved!
    Go to Solution.

    Hi Principiant,
    I tried to reproduce your LV VI, which calculates the sine from the loop counter and get a cycle time of 0,125 microseconds, calculating the sine of every degree (0 .. 359). This means 45 us / cycle, which is 22222 Hz.
    So it is likely that the communication with Your USB- device is the bottleneck. Is this device capable of buffered output? This would be preferable, it puts a block of data (pattern) into a FIFO and the device sends it to the DAC on its own.
    greets, Dave

  • How do you increase the speed of your iPhone 4?

    Sometimes when switched from page to page on the home screen is delayed. Also, typing is delayed at certain times.

    Your iPhone must has a lot of junk file. I tried a tool for this problem--Macgo iPhone Cleaner. It is helpful as their description--an excellent iOS cleaner tool to free up storage space for more fun securely. Whenever you found your iPhone running slow or running out of space, you can ask help from it. If you want to have a try.Search "Macgo iPhone Cleaner" at softonic site's check box.It has versions for MAC OS and Win OS.

  • Whats the best option to increase the speed on my mid 2010 macbook pro?

    What choices are there for me to increase the speed of my computer ?

    More RAM and a SSD. If you're running under 8GB of RAM, I would recommend upgrading to 8GB. You can check out Crucial or OWC for the correct RAM configuration for your model.
    While you're at Crucial, I would also look at the available SSDs that would fit your machine - just use the System Scanner tab, and it will show you the recommended upgrades.
    RAM and SSDs are about the only things you can upgrade to make your computer faster.
    If you're new to SSDs, see my user tip here -> https://discussions.apple.com/docs/DOC-4741.
    Good luck,

  • Upgrading to a larger Harddrive?

    I'm trying to upgrade to a larger harddrive for my HP Pavilion dv6448se from an 80gb to a 500gb.
    What kind of harddrive do I need, specifically? I bought one from Western Digital and it doesn't have the right connectors.
    Can anyone help me?
    This question was solved.

    The connector bar is on the old drive in the caddy. It is a plastic piece that has female ports that accept the male SATA plugs on one side and then a different connection interface proprietary to HP on the other. Look at a new, bare drive and look at the old HP drive in the caddy. The thing that makes the HP drive different is what has to be removed.
    This is what the connector looks like. The bottom part goes over the SATA connectors.

    I own a MacBook Pro 13 inch [dec 2009] 4gb ram. I'm upgrading it to 8gb. Can I increase the speed of the ram from 1066 to 1333 Mhz..?
    Which is the best company and is it necessary to buy it from the Apple store.

    Let's clear the air here between fact and fiction.
    Brand of RAM has little if anything to do with its quality.
    A reliable vendor is more important that brand of RAM.
    Installing faster rated RAM than required for your computer doesn't result in a faster computer. The RAM still runs at the speed of the system's memory bus.
    Installing slower rated RAM than required for your computer will make the computer run slower.
    Using faster rated RAM is a tricky business. Sometimes it will work and sometimes it will not work. This may be due to other factors related to your computer's memory bus speed and clock speed as well as other characteristics of the RAM such as CAS Latency (CL.)
    The reliable thing to do is use RAM that meets the specifications set for your computer. That information is found in either the user manual or the system specs.

  • My performance is very slow when I run graphs. How do I increase the speed at which I can do other things while the data is being updated and displayed on the graphs?

    I am doing an an aquisition and displaying the data on graphs. When I run the program it is slow. I think because I have the number of scans to read associated with my scan rate. It takes the number of seconds I want to display on the chart times the scan rate and feeds that into the number of samples to read at a time from the AI read. The problem is that it stalls until the data points are aquired and displayed so I cannot click or change values on the front panel until the updates occur on the graph. What can I do to be able to help this?

    It may also be your graphics card. LabVIEW can max the CPU and you
    screen may not be refreshing very fast.

  • How to increase the speed of Zoom on TIFF image

    Hi everyone,
    i m doing zooming operation on tiff image.
    when i applied zoom in operation on image which have properties
    Bit per sample =1
    Image Length = 2200 Pixel
    Image Width = 1700 Pixel
    Resolution(x) = 200 dpi
    Resolution(y) = 200 dpi
    then it require 2 sec.
    then i apply the same code with tiff image which have properties like,
    Bit per sample =1
    Image Length = 3300 Pixel
    Image Width = 2500 Pixel
    Resolution(x) = 300 dpi
    Resolution(y) = 300 dpi
    then it require 9 to 10 sec.
    my code is:
    RenderedImage src= oriRndImage[selectedButtonIndex];(orirndImage is Rendered
    Iamge)
    //Transfer Current RenderedImage object into BufferedImage object
    Raster ra= currRimage.getData(); //it take time.
    DataBuffer db = ra.getDataBuffer();
    SampleModel sa = ra.getSampleModel();
    ColorModel cm = currRimage.getColorModel();
    final BufferedImage currImage = new
    BufferedImage(cm,Raster.createWritableRaster(sa,db,null), false, new
    Hashtable());
    //Create new Bufferred Image
    BufferedImage bi = new BufferedImage(zoomW,zoomH, BufferedImage.TYPE_INT_RGB);
    Graphics2D g = bi.createGraphics();
    double scaleW = (double)(zoomW)/(double)(prev_width);
    double scaleH = (double)(zoomH)/(double)(prev_height);
    transAtZoom = AffineTransform.getScaleInstance(scaleW,scaleH);
    g.drawRenderedImage(src, transAtZoom);
    can any one plz suggest me the way ,how to increase the speed. of Zoom effect?

  • How can I increase the speed at which I write to a spreadsheet?

    We are trying to acquire data rapidly during a 1.5 second test. We are able to acquire the data at a variety of speeds, but are unable to write it to an Excel spreadsheet any faster than 10 Hz. Is there a way to speed the writing to a file or are we stuck with this rate?
    Thanks

    Hello,
    I noticed your post was in the DAQ group, but you didn�t mention which
    programming language you are using. This answer is tailored to
    LabVIEW, but if you are using something else, let me know. Since you
    are running such a short test, it might be easier to acquire all of
    your data first and then write it to a spreadsheet file.
    If this is not preferable, you could use lower-level file VIs. Using
    a VI such as the �Write To Spreadsheet File� within a while loop is
    inefficient since it opens and closes the file each time it writes a
    new value. One of the fastest ways to write to a file is to first
    open the file. Then in your while loop, perform your data acquisition
    and write to the file. Finally, close the file after your while loop
    completes. If thi
    s is what you are already doing, you could try
    writing to a binary file instead of an ASCII file.
    Try acquiring your data and then writing it to a file. Or try using
    lower-level file VIs to increase the speed of file writing. If this
    does not address your problem, please provide some additional
    information such as the VIs you are currently using to write to the
    file or post all or part of your VI.
