Will SSD be affordable

By Alex Gerovski


Netbooks were specified for being small and light from the start. These are mobile windows on the web which can be carried around anywhere you travel. The absence of an optical drive has drastically bought down the weight of an netbook when compared with a laptop.

But there is still an element inside netbook that prevents it from being truly light. That is the hard drive. A hard drive consists of 3 or maybe more platters which are electromagnetic disks on which data is stored. It has an actuator arm with heads on the tip that read and writes data from each side with the disk.

These traditional hard drives weight too much and noisy. They occupy a lot of space within the architecture of a compact computer. Also as they are made of moving parts they are really susceptible to damage when receive a shock be a catalyst for corruption and loss of data.

As compared to these a Solid State Drive is free of disks or some other moving parts. They happen to be comprised of many microchips which are used to save data. They are really effectively similar towards the flash drives that people plug into USB ports to keep data. As they do not have any moving parts they really are very silent.

In addition they weigh way less than conventional hard drives they do not possess heavy platters. And that is great for netbooks which make them even lighter. They really are incredibly not hard to install and do not require different motherboards because the interface is similar to hard drives.

These SSD are also lightning fast you really need to use one to view how fast they can indeed be compared to a magnetic hard drive. They have got virtually no spin up times as a consequence of absence of disks the random access time is merely 0.1 milliseconds while at the same time a hard drive takes ranging from 5 to 10 milliseconds.

In case of hard drive the access time is longer if the hard drive is fragmented meaning data is divided and stored in various parts of the disk. This can lead to a delay when accessing a selected data. It does not happen with SSD because they do not fragment data to hold it.

Because there are no moving parts in an SSD it does not require maintenance and would not encounter mechanical breakdowns. The information stored on a hard drive is also susceptible to electromagnetic interference be a catalyst for loss of valuable data. Nothing of this sort can affect the info stored on an SSD.

The only drawback from mass scale deployment of SSD is the cost factor. When it comes to cost for each Gigabyte of data to be stored an SSD is expensive in comparison with conventional hard drive. Though case of every new technology the price tag on SSD are anticipated to come down with time.
