SSD (Solid State Drive) is the storage media (mass storage drive / hard disk) that is widely used today, since some time ago prepared to replace the hard drive. It can be seen from the use of the latest SSD (Solid State Drive) in a notebook.
The use of the term solid state, refers to the use of semiconductor devices on electron tubes, but in the present context, has been adopted to distinguish solid-state electronics from electromechanical devices. Therefore, solid state drives are more robust than on the hard disk.
SSD (Solid State Drive) is no longer consists of a disc and disc read-armed head, however, SSD (Solid State Drive) consists of a collection of chips such as flash, or commonly known as NAND Flash memory. Chip on NAND Flash memory type is similar in shape like a memory chip DDRAM, but NAND Flash is non-volatile, which means that does not require electrical current to maintain the data located on it.
There is a 2.5-inch SSD (Solid State Drive) as drive-sized notebooks, and large 3.5-inch SSD (Solid State Drive) for desktop computer hard drive, the IDE connector is greater. For now, the SSD (Solid State Drive) with the world's largest capacity reaches 1 TB which is a breakthrough product from Toshiba and Keio University in Tokyo. Size of the SSD (solid state drive) is just a postage stamp. Compared to 2.5-inch hard disk drive, the new SSD (Solid State Drive) is about 90 percent smaller but its capacity reached 1TB.
