Solid State Drives : Slowly making its way

First of all I would like to go bake to 80's and show you a picture and guess what its a hard drive!!! And size? massive 5 MB !!! I am sure you will laugh at it now. We have TBs of HDD in our notebooks nowadays. But its only problem is it has a mechanical head that runs at 4200 to 7200 rmp. It is like a jet engine. So what? It is vulnerable to fail if you drops it and it consumes more power. It is a mechanical HDD at the end of the day. Though the technology is improved enormously and there are many protective measures to prevent it from failing we certainly need something that can replace it in the future for better performance and low power consumption. As long as you have desktop you don't bother much about power consumption but as soon as you move to notebooks you started to think how can I make my notebook run for longer without charging its battery. There comes the SSDs in picture. In simple terminology it is just like a flash drive. Why it is called SSD? Simple because it has no moving parts like mechanical HDD and that makes it more reliable and less power hungry. SSD are basically a NAND based flash drive.This means no moving parts, and thus no spin-up speed, which results in shorter boot times. It also means faster read speeds from idle, and faster write speeds for larger files.SSD can be much smaller than mechanical HDD.MicroSD cards are a good demonstration of this, as is the seemingly endless increase in the capacity of USB keys.The nature of flash memory also means that it can survive through a larger temperate range, with some flash drives operating at up to 70 degrees Celsius. Though there are many advantages it is still emerging while mechanical HDD is mature technology but it will eventually replace them. As I write this Intel has released 320GB SSD this month and size will grow and price will drop. So stay tuned and keep your eyes open for SSD.
