SSD (Solid State Disk, Solid State Drive) is a permanent memory such as flash memory, or non-permanent memory, synchronous dynamic random access memory (SDRAM) Computer, an external storage device. SSD is used in portable computers instead of conventional hard drives. Although there has no can rotate the disk structure in the solid state drive, but by people’s naming conventions, such memory is still referred to as “hard drive.”

Because the technology of SSD and the traditional hard drive is very different, so a lot of emerging storage vendors come out. Manufacturers only need to purchase the NAND memory, coupled with appropriate control chip; then they can create SSD. The new generation of SSD commonly used by the SATA-3 interface.

What are the advantages of SSD?

And compared to conventional hard drives, SSD with low power consumption, noise, vibration resistance, low heat characteristics. These features not only make the data can be more safely preserved, but also to extend the continuous operation time of battery-powered devices.

The initial high-end solid-state hard drive performance with the fastest traditional hard disk each outcome, but with the continuous development of solid-state hard drive, the performance of high-end SSDs has gone beyond the traditional hard drives.

Most advantages of solid state drives (SSD) over traditional hard drives come from the characteristic of data being accessed completely electronically instead of an electromechanical machine. Solid State drive does not have moving parts. All the storage on an SSD is handled using flash memory chips. The power usage is a key role for the use of solid-state drives in portable computers. Quick data access is another important advantage of using SSD drives. On the other hand, traditional hard drives currently excel by offering much more capacity for the same price.

With businesses using their servers on a daily basis, the more efficient the server can run the better it is for the company. With its quick speeds and wiring, SSD is likely to continue to grow as a viable alternative to standard hard drive memory shortly.

The biggest problem with the current popularity of SSD is the costs and write times. Volatile memory or non-volatile memory, and its cost per megabyte is much higher than traditional hard drives. Only a small capacity SSD prices can be paid by most people. And because flash memory has a certain writing life, after the expiry of life data will not reproduce. Thus it becomes another obstacle to SSD being accepted by the public
