Solid State Drives (SSD) is a term used in computer literature. SSDs refer to types of memory which does not have any moving objects. Hard disk drives we use every day on our computers have a spinning disk and a moving head inside them. Even though these Hard Disk drives are ideal for daily home usage, they may produce unreliable results if a significant force is applied. Therefore in these circumstances, SSDs provide much better dependability.
As SSDs do not have any mechanical parts inside them they are ideal for field and mobile devices. Since 1990’s the military and other organizations which demanded high data reliability has been using SSDs in their equipment. Today, most of the laptops, netbooks and high capacity MP3 players are migrating to SSDs because of its benefits. SSDs are silent during operation and they are much faster than mechanical drives. Also they consume less power – which means improved battery life for mobile devices.
Few years ago consumers had a reluctance to buy Solid State Drives because of their high price. However now the price has come down to a more affordable range and it continues to drop as the competition and market maturity increases.
Along with all those benefits, there are still few negative points with SSDs. Solid state drives are still limited in their individual capacity. Even though there are no mechanical parts, the performance of SSDs can still degrade over time after a large number of re-writes.
There are also hybrid drives under development which uses SSDs as a buffer for larger mechanical hard drives. These drives provide the benefits of having access to a large capacity disk drive with much faster speed and reliability.
Advantages and Disadvantages of Solid State Drives (SSD)
The interest in SSD’s has become overwhelming, its begun a storage race with the normal HDD that aren’t quit out of the game yet but with more and more SSD’s coming into the market, it looks as if they are taking over in a big way. Let’s begin with the question of exactly what is an SSD and what are the benefits. The easiest way to explain what an SSD is, it’s a flash drive larger than the ones you place into your phone or your camera’s. The memory is much like the ones used in ram but can retain the memory without power
The SSD is totally different from RAM, in that it is made of flash memory rather than volative memory, thus bringing into existence the term ‘solid state memory’. With computer memory (RAM) when you turn off the computer it wipes the memory clear, basically its starts free and clear on startup. With an SSD, like a hard drive, it permanently stores and remembers the data you put on it. That data can be anything from an OS to a word document.
The advantages of a SSD are numerous. First and foremost the sheer speed of the SSD is the most obvious feature. There is no requirement for the disk to spin and the arm to find the exact position of the information it is retrieving. SSD’s are essential large flash drives that zip information to and from drive to motherboard. Boot-up times have been cut in half since there is no spinning involved, it’s almost as fast as our brains telling our fingers to type or tell our legs to walk. Initial performance results of the SSD were very good; however, the write speeds were its downfall, some being as low as 14bs. Another great advantage of the SSD is how silent it runs and lack of heat created through the SSD. From these benefits come additional benefits such as unbelievable lifespan and incredible reliability.
But, there are some disadvantages to the SSD, these being price and storage capacity. While we see prices dropping gradually, people are still looking to spend around $250-$1800. Size is then another consideration. We can run out and grab a 256GB SSD as seen here for around $500, but the 64GB have just gone into value in the market.
It’s easy to setup an SSD, backup your system with a disk imaging program, pull out the HD and replace it with the SSD (both being SATA of course) and restore your system. Similarly, you can do a clean install just as easily as having the HD inside the system. There are no additional cables or carriages to worry about. The solid state drive has become the high-end, highly sought after storage drive. It has quickly found a position where, if manufacturers can find the lower prices, higher storage capacity and availability, the SSD could threaten the mere existence of the HD. The first obstacle of performance was surpassed long before many knew what SSD stood for. There appears to be so many benefits to owning an SSD for business or personal use, the simplicity of the SSD lies in the absolutely break neck speed in which it completes its tasks. Quicker start-ups, incredible performance, no moving parts, less heat, longer battery life, incredible reliability and durability will soon dominate the market and possibly rid of the old HDD
