SSD Made Simple
Keep hearing people talking about them, but not sure what on earth they are and more importantly, why should you care? Let us tell you a bit about the new technology that's changing the face of storage.

Solid State Disk - what's that mean then?

A solid state disk is a device that from the outside behaves a lot like any other hard disk. On the inside, however, SSDs are quite different. Regular hard disks rely on spinning magnetic platters, whereas SSDs use the latest flash memory chips as storage... without a single moving part.

What makes an SSD better?

There are three main advantages that SSDs bring over traditional hard disks.

  1. SSDs have no moving parts. This means they're not susceptible to same mechanical failures as hard disks. A knock to an SSD will do it no damage.
  2. With no platters to spin, SSDs can use less power than a hard disk, which is great news for laptops and netbooks and also means desktop PCs can be made more efficient.
  3. The biggest benefit is performance. No longer bound by the time it takes to move mechanical parts, SSDs deliver a big leap in read and write speeds. That equates to faster boot times, quicker program launches and less time spent waiting for your desktop / notebook to "think about" doing something.
How does a Desktop / Notebook use an SSD?
An SSD drive has a SATA connection just like most modern hard disks. Plugging it in the same way as you would a hard disk will make it appear to the computer as a storage device. It's then ready to use - simple as that! How four user groups can really reap the benefits of SSD technology?

  1. Travellers & business users - Notebooks, especially smaller models and netbooks tend to have lower performance. Replacing the hard disk with an SSD can help speed things along whilst also extending battery life. Better still, the lack of moving parts in an SSD means it can take a few bumps and knocks with no ill effects. 
  2. Home user -If you spend more time waiting for things to load than you do actually using them, the performance boost of an SSD drive could be just what you need to get more out of your PC.
  3. Gamer - With enormous levels and more graphical detail than real life, there's a lot of data to fetch when loading games. An SSD will help you spend less time loading maps and more time laying down your awesome skills. 
  4. Photographer -If you combine an SSD and a hard disk, you can use the SSD for the operating system, applications and as your image editing software's scratch or working area, while the hard disk can be used to store your original and edited photos. With the SSD handling all the intensive stuff, the editing process will be so much quicker. Aren't there other ways to speed things up?
Yes, there are, but if you want the benefits described above, there are few ways that compare to an SSD. Intsalling an SSD is THE single most cost effective upgrade you can do for your PC or laptop - It will boost your desktop or laptops performance, speed and efficiency.  But couple an SSD with a RAM memory upgrade and watch your machine really fly!!! Why should I buy an SSD?
  • Faster - It's five times faster than a hard drives and can boost your system - from drastically increased boot up time, to faster internet browsing, to smoother performance when running a variety of applications and programs.
  • Cost efficient - by replacing and upgrading your hard drive, an SSD lets you revive your system without stretching your budget.
  • Reliable   - offering  increased reliability dropping your notebook no longer means losing your data and  
  • Silent - Heat generation and background noise is reduced.
  • Guaranteed - three-year warranty with  free technical support.
