There was a time when a computer was as big as a classroom, consisting of transistors made out of glass and you had to use punch cards to interface with it. Today, however, not only have these machines been made more compact, but their processing speed has been improved drastically.
There are various components of a computer which account for this performance improvement such as the Main memory (RAM), Graphics Cards (GPU), Processors and last but not the least the Hard Disks. The technological enhancements over the time have not only brought faster, larger and more compact magnetic Disks, but they have also introduced SSD’s (Solid State Drives) which provide a drastic speed improvement from its predecessor.
SSD Feature Highlights Compared To HDD
SSD, the solid State Drives, are the next generation in computers storage medium and bring forth a lot of changes from the older Magnetic Disks. Following are some of the key features which set the SSD apart from the traditional HDD:
Speed: SSDs are staggering improvement over the Toshiba’s 2.5 inch laptop HDD which gives an internal transfer rate of 286MB/s making your Windows boot up in 24s as compared to 95s with an HDD.
Form Factor: The SSDs today commonly come in a size of 2.5 inch, which is similar to the size of Laptop HDDs and smaller than the 3.5 inch HDD’s for Desktop computers. They also use the standard SATA connectors making the laptop HDDs easily replaceable with the SSD, however you will need some additional hardware to replace the 3.5 inch Desktop HDDs.
Data Storing Technology: SSDs rely on memory chips also known as NAND Flash memory, which are immovable as compared to the HDD’s rotating Magnetic Disks. SSD when compared to HDD are not only lighter but virtually make no noise at all. SSDs also generate relatively less heat. Data recovery in the SSDs is also possible with use of special equipment which involves opening the drive and de-soldering memory chips.
Compatibility: SSD’s use the traditional SATA interface so they can easily replace the HDD without much hassle but still there are some SSDs which will not work on older laptops. Sometimes you need to change some BIOS settings on your computer to get the SSDs to work.
Life expectancy: The life of SSD as compared to HDD is smaller, around 18 years in total.
Upgrading : For SSDs, the usual hard drive replacement steps would have to be followed and an adapter would be needed for desktop because of their 3.5 hard drive bay.
In today’s world the average consumer wants more compact solutions with greater speeds and high reliability, and the advancements in technology are striving to achieve just that. SSD’s are a step towards bringing these requirements to fruition. Although SSD’s are more expensive and have lower Storage size than HDD’s at the moment, but at the rate technology is advancing this won’t be a bottle neck any more.
