What is SSD Drive

As we all know that hard drives are the part of computer system which stores the data of computer. SSD stands for solid start drive. The function of these drives is same as that of normal hard disk drives (HDD). HDD have spinning disks and movable read/write heads which store the data where as SSD use microchips and data are retained in non volatile memory chips and one of the best things about it is that it does not contain any moving data in it.

So it makes it work less unlike HDD. In HDD there are few risks for example, physical socks, lower access, latency and quieter but SSD don’t have to face these issues at all. The interface of hard disk drives is the same as SSD thus SSD easily replace them in most applications.

History of SSD Hard Drives:

In the era of vacuum tube computers SSD came from two similar technologies, core memory and card capacitor read only store (CCROS). This was happened in 1950. But in 1970s and 1980s SDD were implemented in semiconductor memory for supercomputers. SDD were highly taken in hand because it makes expensive computers quite seldom use. So, this is one of the benefits provided by SSD to computer industries.
The fast growing technology of 2010 NAND based flash memory is used in SSD in which memory is retained without power. SSD helps the situations in which faster access is required and do not require permanent power supply with it, back up will be there after removing the power.

Functions and Applications of SSD Hard Drives:

There is one drive which combines HDD and SSD on one unit and that is Hybrid Drive.SSD have faster starting facility because as mention earlier it does not contain disks to spin for booting. It has fast random access because it does not need any seeking motion like hard disk drives. Plus it has silent functioning due to less physical work. It consumes less power than hard disk drives due to this laptop manufacturer keep them as an additional optional to standard HDD. Lack of physical work reduces the risk of mechanical failure. This technology is immune to magnets. Its size varies according to the requirement. Writing/reading data is secure as less failure occur which means there is less chance of data damage. SSD can perform parallel reads on multiple sections of memory which decrease the seek time of hark disk.

In mobile computing flash bases, solid state drives were costly for it. SSD are becoming popular in markets for notebook PC due to its less size and physical work. SSDs have been appearing in mobile PCs and a few lightweight laptop systems, adding significantly to the price of the laptop, depending on the capacity and transfer speeds.

Conclusion:
This is a rapid developing technology. That is why it is been used in many applications. Until 2009, SSDs were used in mission critical applications where the speed of the storage system needed to be as fast. Since Flash memory has become a common, the falling prices have made it financially attractive for many other applications. Organizations that can benefit from faster access of system took this technology in hands. The list of applications which could benefit from faster storage is vast. Any company can assess the ROI from adding SSDs to their own applications to best understand if that will be cost effective for them. Flash-based Solid-state drives can be used to create network appliances from normal PC hardware. A flash drive which is writing protected containing the operating system and application software can substitute for larger and less reliable disk. Appliances built this way can provide an inexpensive alternative to expensive router. Thus this technology helps in any possible way to replace hard disk drives.
