Speed up Your Computer

The Slowness Problem.

One of the problems with computers is that as they get older, new operating systems and software patches come out and inevitably the computer seems to slows down. When it gets to the place where you get frustrated with your computers speed, you are supposed to follow the script and go out and buy another computer. But there may be another way! Over the last couple of years I’ve managed to bring new life to a few old Windows and Mac computers and generally the cure is less costly than a new computer. The cure is what’s called an SSD (Solid State Drive). They range in price from about $100 to over $1000 but a cheap 1Tb drive is only about $375.

How it works

The reason this works is because the slowest item in your computer is your hard drive. The hard drive is where almost everything is stored. So when you first press the power button, the computer goes to the hard drive and loads the programs that make it work – the user interface, the drivers for sound systems and the screen and all that stuff. When you do anything from there on, the computer goes back to the hard drive to get more stuff or write files etc.

However most computers older than a couple of years will have a mechanical hard drive (not an SSD). So when they need something from the drive, the systems moves the read heads to the right place and then extracts the information from the files store on the magnetic disks that are spinning very quickly beneath the heads. It takes a while for the heads to move into the right place and then the reading speed is determined by, amongst other things, the spin rate of the disks so there is a physical limit to how fast they can read the information.

With an SSD drive, everything is stored in integrated circuits – or chips. So there is nothing mechanical to move. The system simply tells the chips to give it the information stored at a particular location. As you can imagine this is a much faster way of accessing the files. In fact a friend of mine said he measured his SSD drive and sometimes it was as much as 30 times faster than the old one.

But First Check This.

So how do you replace the hard drive? It is fairly simple but there can be some catches. Before you start, there are some things to check.

You should check what disk storage you are currently using on your computer. On a Mac click on the Macintosh HD icon, press and hold the command key then press the I key. That will give you a window that tells you the capacity of the drive, the used space and the available (unused) space on your drive. In Widows, navigate to your hard drive icon then right click on it and select properties.  It will give you a graph with used space, and free space on it. You should purchase a hard drive with enough for your current situation plus at least 20% more because both operating systems use some of that free space from time to time.

Next you should check the physical size of your drive. If you have a laptop, the physical  size will be about the same size as a new SSD drive but if you are replacing the drive in a desktop, you will need to purchase a cheap adapter to fit the smaller drive into the larger space.

My 2011 MacBook

If you are planning to replace a drive in a MacBook Pro older than 2012, just be aware that my experience tells me, if the battery is not an Apple battery, there may be some speed issues with booting from the SSD. Apple seems to measure whether the battery is one of theirs and slow the computer down for some reason I can’t explain. It runs fast after the system is loaded but booting takes a while. Maybe it was something I did wrong! The latest operating system uses the hard drive in a different way to the older operating systems. So it could just be the new file system or the hard drive or something else. Maybe I should just go back to the older system!

What to Do Next.

Do a backup of your files as would normally do, then start the steps below.

  1. Set up the new drive as an external USB drive for your computer using an external drive case.
  2. Copy the whole of the old hard drive to the new drive using specialist copy software. For windows I use Easus copy software because it’s free. Here is the link.  For my Mac, I use the built in Disk Utility using the clone function. Use this link to find out how to do that.
  3. Remove the old hard drive. From some computers that’s easier than others. So you probably have to Google how to replace the hard drive in your particular computer. In some Mac computers you simply remove the bottom cover but in iMacs, you probably have to remove the screen to find the old hard drive. That’s easier in iMacs from 2011 and before though if your careful you can replace the hard drive in the others. However, in the 2009 – 2011 iMacs, there was a heat sensor built into the drive and when you replace it, the fan will run flat out. You can fix that with some simple free software. Follow this link for details.
  4. Fit the new drive into your computer. If you are replacing a laptop there should be no issue as the new drive will be a small physical size like the old one. If you are replacing a desktop hard drive you should buy a bracket that allows the new drive to adapt to the old space.
  5. Insert the new drive. Put the covers back on and switch it on to make sure it works. If it doesn’t go back to the old drive and start again!

Your computer should be better now!

If all this seems a bit high tech for you ask your trusted local computer tech/site about it.
