With the popularity of mobile office, mobile hard disks have naturally become an indispensable storage tool for office workers. But the core of the traditional mobile hard disk is a mechanical structure, and there has been little development for so many years. Until the emergence of mobile SSDs, with its ultra-fast read and write speed quickly attracted a large number of users, what is the difference between mobile SSDs and mobile MECHANICAL HDDs? Let's take a look!

The traditional hard disk is a mechanical structure, such a structure determines that it will make noise when working; the seismic performance is weak, especially when the disk is working, it is easy to damage the disk when it encounters a violent impact; and the volume is large, inconvenient to carry; of course, the most important thing is that its read and write speed is slow.
For example, Western Digital's ordinary 1T mobile hard disk, now this mobile hard disk on JD.com has not marked its reading speed, and it still uses a USB3.0 interface, which means that the traditional mechanical mobile hard disk has not taken the read and write speed as a selling point. In the past two years, the read and write speed of the new mobile mechanical hard disk is generally around 100MB/S, which is often very difficult to transfer large files. But the mobile mechanical hard disk is not without advantages, first of all, it is cheap, Western Digital's 1T mobile hard disk is priced at more than 300 yuan; secondly, it can theoretically carry out unlimited reads and writes.
Let's take a look at the mobile solid-state drive, the mobile solid-state drive is a circuit board inside, the top is welded with the main control chip and memory particles, the mobile solid-state drive is often small, the seismic performance is good, and the read and write speed is very fast, these characteristics make it widely used in removable storage.
Now many people see the many advantages of SSDs and start to buy SSDs instead of MECHANICAL HDDs. Not enough SSDs also has a big disadvantage, that is, the price is high.
At the current market price, the price of those first-line brands, the same capacity of solid state drives is on average about 3-4 times the price of mechanical hard disks, in this case, how to choose?
In fact, it depends on your use, if it is just to store information, I suggest you still buy a mechanical hard disk is more cost-effective, because of its large capacity, cost-effective, and if in case of damage, the data can also be recovered through technical means, some very precious data will not be completely reimbursed.
And once the SSD is damaged, the data is lost, and now says that technology, cannot be recovered, can only disappear completely.
Therefore, from the perspective of data insurance, it is still relatively safe for mechanical hard disks. If you want to buy, buy big brands, such as Western Digital and Seagate, are all big brands that you can trust.
However, if you are trying to improve the speed and efficiency of the system, I still recommend that you use an SSD, because the SSD can very obviously increase the speed of the computer, more obvious than if you change the memory and CPU effect. Many people seven or eight years ago after the old computer replaced by an solid-state drive, there is a new life, the boot speed from one or two minutes to more than ten seconds, or even less than 10 seconds, the shutdown speed is faster, Xiaobian's own old notebook, after replacing the solid-state drive reinstallation system, the original half a minute, the current shutdown time is about 1 second.
And choose the solid-state drive to do the system, do not need to choose the capacity is too large, mainly the price is too high, there is no need, the average person with 128G or 256G is completely enough, of course, to choose those big brands, such as Kingston, SanDisk, Intel, Western Digital, Seagate, Samsung, etc., although the price is slightly expensive, but it is not easy to have problems, and the use time is also long.
The same is the mobile hard disk, the solid-state price is several times that of the machinery, how to choose? My opinion is that according to your needs to choose, if it is mainly for storage, it is best to choose a cost-effective mechanical hard disk, if it is to improve the performance of the computer, then choose an SSD.
