1, the principle of solid state drive is a mainly flash memory (NAND Flash) as permanent memory computer storage devices, solid state here is mainly relative to the mechanical arm driven magnetic head rotation to achieve the read and write operation of the disk, NAND or other solid state storage to the potential high and low or phase state of the different records of the 0 and 1.
2, solid state hard drive media using SATA 3, M.2 or PCI Express, mSATA, U.2, ZIF, IDE, CF, CFast and other interfaces. However, due to the price and storage space and mechanical hard disk has a huge gap, solid state hard disk currently still can not completely replace the mechanical hard disk.

Solid State Drives
1, solid state drives and mechanical hard drives compared to the read and write speeds are far superior, which is its main function, but also has a low power consumption, no noise, anti-vibration, low heat characteristics, these features can be extended by the battery-powered computer equipment running time.
2, solid state hard drive anti-vibration and anti-drop traditional hard disk are disk-type, data stored in the disk sector. And solid state drives are made using flash memory particles (i.e., mp3, U disk and other storage media), so there are no mechanical parts inside the SSD solid state drive.
