Today, the editor will share with you the relevant knowledge about the advantages of choosing solid state drives for computers. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

No matter what kind of computer you buy, solid state disk (SSD) is recommended to install the computer in 2018.

Solid-state drives are not only fast to boot, but also bring a smoother sense of control. The simplest example is to open a browser, mechanical hard disk may take 3 seconds, solid-state disk 1.5 seconds, so more than a second difference, the feeling is different.

Over the past 20 years, the performance of i7-6700K 386DX40 CPU has improved thousands of times from 1995 to now, memory capacity has increased from 1m to standard 8G (8000 times), hard disk capacity has increased from 210m to present 1TB (5000 times), but hard disk speed has increased less than 10 times (from 5400 rpm to 7200 rpm, coupled with performance improvement brought about by increased disk density), due to the inherent shortcomings of mechanical hard drives. Solid-state hard drives are 4-6 times faster than mechanical hard drives, which can be said to be a qualitative leap. Now the real bottleneck with the computer is not CPU, but the hard drive!

Due to the high price of solid-state hard drives, there are three mainstream options for installed hard drives:

1. Use 120g SSD single hard drive (for customers with low capacity requirements, photos and video materials can use free cloud disk.)

2. Use 240g SSD single hard disk (for customers with certain capacity requirements, photos and video materials can use free cloud disk.

3. Use 120g SSD+1TB mechanical hard disk (double hard disk scheme, taking into account the requirements of speed, price and capacity.)

From the perspective of development prospects, the price reduction of SSD is an inevitable trend, and solid-state hard drives will replace mechanical drives in the household field. If the price factor is excluded, the biggest disadvantage of SSD compared with the mechanical disk is that once it is damaged, the data cannot be recovered (although the mechanical disk may not be able to recover 100%, and the recovery is expensive). Therefore, non-confidential information, such as personal photos and videos, can be placed on the free cloud disk. If you want to keep it secret, you can buy a mobile hard disk.

Remarks: three conditions are necessary to give full play to the power of SSDs.

1. SATA3 interface is required.

The old model only has SATA2 interface, so switching to solid-state hard drive will not give full play to its performance. To put it simply, a solid state hard drive that can run 10000 points can only run 6000 points with the SATA2 interface (but it is also more than twice as fast as the 2000 points of the mechanical disk).

2. The hard disk mode is AHCI.

The current motherboard defaults to this mode, only the old motherboard may default to IDE, which needs to be modified BIOS.

3. 4K alignment must be done.
