What is the difference between solid state hard disk and mechanical hard disk

By  Dahlia Bronson 2020-01-08 1533 56

For DIY installation, the hard disk is a very important part, may be home computers, we are accustomed to the use of mechanical hard drives. However, the slow transmission and short life of the mechanical hard disk restrict the whole machine. Now, even if the price of SSDs is high, it will not affect the choice of SSDs. The former SATA interface has now developed into a high-performance M.2 interface, which is constantly updated. What is the difference between solid state drives and regular hard drives? What's the difference? Let's take a look at it.

Note: the ordinary hard disk mentioned in this article is the traditional mechanical hard disk.

The advantages of Solid-state drive:

1, first of all, fast transmission speed; 2, long service life; 3, easy installation, easy to carry; 4, no noise in the process of application.

The difference between Solid-state drive and ordinary drive:  

SSDS have the following advantages, which are the difference between the two: 

1, SSDs start quickly.

2, read fast, for example, the same configuration of computers, solid-state disk laptops from boot to the appearance of the desktop took 18 seconds; traditional hard disk laptops took a total of 31 seconds.

3, when reading data, the addressing time is not related to the location of the data storage, so disk fragmentation does not affect the read time.

4, SSD has a wider operating temperature range.

5, solid state disk is small in size, light in weight and easy to carry.

6, DRAM solid state drives write faster.

7, when the solid state drive is working, there is no need for mechanical motors and fans, so there is no noise.

8, low-capacity solid state hard disk, in the working state, the energy consumption and calorific value are lower.

9, the biggest advantage is that there will be no mechanical problems, and not afraid of collision, impact. When a laptop is dropped or hit by other objects, the likelihood of data loss can be reduced.


Disadvantages of solid-state drive:

1, high price

2, small capacity

3, data is not easy to recover

The above are many advantages and disadvantages of SSDs shared by Xiaobian. The problem of SSDs is that the price is high, so they have not been fully used yet. When you really use solid state drives, you will find that computers are smoother and faster to switch on and off. The capacity of solid-state hard drives is expanding, and it can also meet the needs of many big data.
