Difference between solid state hard disk and ordinary hard disk Knowing

1, speed, solid state hard disk transmission speed can reach 500MB / s, which read speed to 400-600MB per second, write speed to 200MB per second. The traditional hard disk read speed limit can not exceed 200MB per second, write speed in the 100MB per second or so. If encountered non-contiguous bulk data, SSD can reflect the extremely fast read and write speeds. Traditional mechanical hard drives have slow transfer speeds due to head seekers and other reasons.

2, security, solid state drives do not have platters, so as long as its chip is not subject to shape extrusion deformation, the data can be safely preserved. The traditional hard disk does not have this advantage, once in the high-speed rotation process platters and magnetic head collision, or even unreasonable contact, will cause damage to the platters, data loss.

3, economic, in the same capacity, solid state hard disk at this stage, the price is higher than the traditional hard disk 3-5 times, but with Moore's law moving forward, solid state hard disk NAND flash chip density will be more and more, then the storage capacity is higher and higher, will one day replace the traditional sub-storage devices.
