Which is better, dual hard drives or solid state drives?Mechanical hard drives use advantages to distinguish lifespan

It's best to use dual hard drives for laptops, so you won't regret buying a 256g solid-state drive.

There are 2 types of computer hard drives:

1. SSD: The advantage is that it is very fast, and the disadvantage is that it has a short lifespan (3-5 years).
2. Mechanical hard disk: The advantage is that it is used for a long time (5~9 years), and the disadvantage is that the speed is not as fast as that of solid-state hard disks.

What is an SSD solid state drive?

Compared with mechanical hard disks, Solid State Drives (SSD, Solid State Drive) are called "solid state" because they do not contain mechanical parts, but are mainly composed of solid-state electronic components, including the main control chip, NAND flash memory and DRAM cache.

• Solid-state drives work on the principle of electrical signal transmission between solid-state electronic components with relatively low latency.
• Therefore, the biggest advantage of solid-state drives over mechanical hard drives is the fast read and write speed.
• In addition, solid-state drives also have the advantages of light weight, low noise and drop resistance.

What is an HDD mechanical hard drive?

The following picture is the internal structure of HDD mechanical hard disk▼

• As the name suggests, the reason why it is called mechanical hard disk, English Hard Disk Drive, referred to as HDD.
• Mainly because there are many mechanical parts inside a mechanical hard drive, such as air filters, motors, disks, heads, head arms, magnets, etc.
• Mechanical hard drives also work based on the precise fit of the internal mechanical components that read and write data on the disk's tracks.

Due to the large number of mechanical parts, mechanical hard drives have many disadvantages:

1. First, they are heavy.
2. Secondly, it is not resistant to falling, and slight vibration will affect the reading and writing of the hard disk.
3. In addition, the operation of mechanical parts can generate a lot of noise.

Is dual hard drive better or pure solid state better?

The following is an analysis of the advantages and disadvantages of the solid-state drive box with dual hard drives:

1) Dual hard drives are usually solid state drives plus mechanical hard drives.

• Solid state drives are used to install the system andsoftwareAs well as storing non-critical data.
• Mechanical hard drives are used to store important data files.
• In pure solid state, the system and data reside on the same solid state drive.
• Today, there is no way to recover data after an SSD failure, so dual drives are better than pure SSDs.

2) Pure solid-state drives can read and write data much faster than mechanical hard drives

• Therefore, if it is a dual hard disk, the security of the data can be improved;
• However, the read and write efficiency is not as high as that of pure solid-state drives.
• This is also a big advantage of pure solid-state drives.

3) Is it better to use dual hard drives or pure solid state drives for laptops?

• It needs to be determined according to the usage of its own computer.
• If it's used for gaming and entertainment, and there's no important data, a pure solid-state solution is the way to go.
• If this is a work computer and you have important data to keep, a dual hard drive solution is best.
• After all, hard drives have value and data is priceless.
• So, some people really regret buying a 256GB SSD...

To give a practical example:

• After using the system for a long time, most of the time for the mechanical hard disk to start is 1 minute;
• In extreme cases, it may be 3 minutes, and the hard disk is still reading after entering the system, and it will take some time before it can be used.
• If you use a solid state drive, you can basically get in in 10+ seconds, and you don't have to wait after getting in.
• Vibration and heat can damage mechanical hard drives, and no matter how well-maintained your disks are, they can still fail.

The speed at which the laptop runs is determined by the hard drive:

• Install the system on the solid state drive, the system runs very fast;
• However, if the solid-state drive has a lifespan of 3 to 5 years, the speed may be slow.
• It is recommended that solid-state drives be used exclusively for system installation, and mechanical hard drives are used to store files.

"My dear, if you don't download things to the system disk, it's the same speed for 3 years; don't download the 360 ​​to update the system, many of the junk software that comes with the 360 ​​will cause the computer to slow down. If everything is used normally, the speed will always be fast."

• The reason you feel rewarded is because helping others is helping yourself.

The difference between SSD solid state drive and mechanical hard drive

The following is the analysis and difference of the advantages and disadvantages of the solid state disk box and the mechanical hard disk.

Advantages and disadvantages of solid state drives

• Advantages of SSDs:No noise, extremely fast read and write speed, anti-vibration, low heat generation, light weight and other advantages.
• Disadvantages of SSDs:The price is high, the capacity is small, and SSDs have a limited number of PE writes, so they have a shorter lifespan than mechanical hard drives.
• SSD lifespan:The average service life is only 3 to 5 years.

Advantages and disadvantages of mechanical hard drives

• Advantages of mechanical hard drives:Large capacity and cheap price.
• Disadvantages of mechanical hard drives:High noise, fear of vibration, generating a lot of heat and slow reading and writing.
• Mechanical hard drive life:Can be used for up to 5-9 years.
