Best SSD 2011

SSD stands for Solid-State Drive, and this is the new type of memory storage that is increasingly becoming popular with laptop and computer manufacturers. Our computers have been functioning on HDD (Hard Disk Drives) for a long time, and this has been the primary area for storing any data that users need. As computers are getting smaller and lighter, the need to replace heavy parts with smaller and lighter variants is becoming all the more important, and this is where the SSD drive comes into the picture.

In essence, SSD is simply a hard drive for storing memory cells and data. You could even call it an overgrown memory card of sorts. Like the HDD, the SSD also has cache memory (areas where data that is accessed repeatedly and often) but the primary difference between the two is the technology that is used. On an SSD the data is written and rewritten on a memory chip inside, and there is no need for an external power source to access this data. Moreover, there is no spinning motor head inside either. This is stark contrast with the HDD, which requires a spinning motor head and a power source in order to activate the read-write heads for the discs on the drive.
