Whereas a standard computer hard drive is made up of a spinning disk on which data is read and written, a solid state drive, in contrast, has no moving parts, and reads and writes data to and from memory chips. This article will touch upon the tpe of solid state hard drive which is based flash memory.
Currently, most computers don't use SSD's (solid state hard drives), but these types of computers are starting to appear.
They are most commonly found in so-called rugged laptops which were designed to be used in a variety of different environments and can function even in extreme weather conditions.
Most hard drives have a spinning platter with a read/write head that has to be positioned correctly for each read/write of data, and these moving parts can be more easily damaged than an SSD, and the data lost.
Why Choose Solid State Hard Drives?
* Noise Free - As a result of not having mechanical parts, there is nothing to make noise. This is perfect for people who is easily disturbed by sounds, when concentrating on work.
* More immunity from vibration and shock - When notebook computers are jostled and constantly moved, this is problematic for conventional hard drives. SSD's are less prone to this problem.
* Speed - For random memory access operations, SSD's are much faster than their mechanical counterparts because there is no moving head which has to move to the correct position. However, when large amounts of data are read sequentially, the two are more on a par with each other. Generally, computers with solid state drives can boot faster and load applications faster than their mechanical counterparts.
* Less sensitive to temperature extremes - Most computers work best when they are in areas that meet very specific temperature requirements. When the temperature is too hot, computers can overheat and stop working, for example. Solid state hard drives are not as sensitive so they can keep working well even in more extreme temperatures.
* Lighter - For smaller capacity SSD's, the weight is less than for mechanical hard drives so the computer doesn't weigh as much either. That makes it simpler to walk around carrying such computers. Additionally, the time between battery recharges is typically longer.
Before deciding on buying a computer using an SSD, bear in mind that they are usually more expensive at present. The price disparity per unit of memory is generally quite large. On the other hand, as the technology gets better, the price of these drives is likely to keep going down considerably.
One more thing to consider is the limited life of SSD's. Even if they are not vulnerable to the type of deterioration that can wear down a standard hard drive, they cannot be written to forever. As a result, just as hard drives with moving parts, they can finally wear out.
For many purposes, a computer using a solid state hard drive is a good choice, particularly since the prices are going down, and the SSD memory sizes are regularly getting larger.
