What advantage of the SSD

- Jul 02, 2019-

Fast reading and writing speed:

Using flash memory as a storage medium, the reading speed is faster than that of a mechanical hard disk. Solid state drives do not use heads, and the seek time is almost zero. The speed of continuous writing is very amazing. Most SSD manufacturers claim that their SSDs continue to read and write faster than 500MB/s! The speed of SSDs is not only reflected in continuous reading and writing, but the random read and write speed is the ultimate meaning of SSDs, which is most directly reflected in most daily operations. Related to this is the extremely low access time. The most common 7200rpm mechanical hard disk seeks time is typically 12-14 milliseconds, while solid state drives can easily reach 0.1 milliseconds or less.

Earthquake resistance:

Traditional hard drives are disk-type and data is stored in disk sectors. The solid state drive is made of flash granules (ie mp3, U disk, etc.), so there are no mechanical parts inside the SSD SSD, so it will not affect the normal even in high-speed movement and even with tilting and tilting. Use, and minimize the possibility of data loss in the event of collisions and shocks. Compared with traditional hard drives, SSDs have an absolute advantage.

Low power consumption:

SSDs consume less power than traditional hard drives.

No noise:

Solid state drives do not have mechanical motors and fans and operate at 0 dB noise. Flash-based SSDs consume less energy and generate less heat during operation (but high-end or high-capacity products consume more energy). There are no mechanical moving parts inside, no mechanical failure, and no collision, shock or vibration. Since the solid state hard disk uses a flash memory chip without mechanical parts, it has the characteristics of small heat generation and fast heat dissipation.

Large operating temperature range:

A typical hard drive can only operate from 5 to 55 degrees Celsius. Most SSDs work at -10 to 70 degrees Celsius. Solid state drives are smaller and lighter than comparable capacity mechanical drives. The interface specification and definition, function and usage of the SSD are the same as those of the ordinary hard disk, and the shape and size of the product are also consistent with the ordinary hard disk. The chip's operating temperature range is very wide (-40 ~ 85 degrees Celsius).


SSDs are lighter in weight and are 20-30 grams lighter than conventional 1.8-inch hard drives.
