Most of the user generally upgrade their computer every 2-3 years . basically they upgrade the processor but one thing that doesn't change is the storage . basically they use the tradiational storage that is hard drive and the problem is with that the capacity of our hard drive increase alot i.e-100GB years back and now 3TB of hard drive . The speed at which you can excess your data hasn't improve alot and SSD come into picture .
The problem with the traditional hard drive that our processor is become really very fast but as our hard drive are not able to send that data to processor every things slow down and becomes a bottle neck .
So generally a SSD drive is much faster than a traditional hard drive but to explain why let me give a quick overview how a hard drive works . Basically hard drive is a mechanical device . just imagine a circullar disk like a cd or some thing like that . that basically is on hard drive . these are known as basically platters and your data is stored on them and to excess that data , your hard drive has a motor inside them and this whole spindle rotates very fast . The 5200 rpm , the 7200 rpm is basically the speed at which the splater can rotates . so as you can imagine to excess the data the hard drive has to rotate a lot and the head again has to move up and down to excess the data and all this basically takes time. its in mili seconds but large amount of data it add up time . Their is one more basic problem with hard drive is that generally the hard drive is very fast if the data is sequential . if the data is in circular form transfer rate get upto 80-100Mbps . But generally in computers the data is not stored like that it is stored in scarted every where in disk and many hard drive have huge problem with that.
So basically with random data your hard drive performance get very low . It can go down to as low as about 2MB per second .
On the other hand these problem are not faced by SSD . Basically SSD is a drive in which data is stored in memory chips . Do not mistake it with your RAM . in RAM when your computer is switched off your data get lost but on SSD data get saved because it is a flash memory . so even your power is off your data is over their . and as you know with memory the excess time is very low so it doen't matter is the data is scattered every where . In a typical hard drive the excess time is 15 mili second compare to the SSD 0.2 mili second , so SSD are really fast . Again even in the sequential data access (i.e data is aligned properly )a traditional hard drive get upto 80-100mb per second transfer rate where as the fast SSD can touch 500MB per second transfer data rate .
So you might be asking what are the practical benifits of using an SSD and what difference will it make in real life .
-Yours windows computer generally take 50 second to boot but with the fast SSD it take only 20 second to boot .
-If you open a heavy software like photoshop etc in traditional hard drive it generally take 10-15 second to open that but with the fast SSD it take only 3 second
So generally loading big program will be lot faster and thus your computer will feel lot faster .
