Simply because distinctive technologies are utilised, the read and create speeds of SSDs are usually a single to many orders of magnitude faster than mechanical really hard drives. Plus the safety of SSD information is also higher than that of mechanical really hard drives. However, as a result of high price of SSD and smaller capacity, etc. The mechanical hard disk continues to be the principle storage disk and has become the mainstream in individual computers.
The mechanical challenging disk itself has only one particular benefit, that may be, substantial capacity. The rest are practically all disadvantages. As an example: it can be quite unsafe. It does not mean that it really is uncomplicated to become invaded, but that the information around the hard disk is quickly damaged and lost. When important data is lost, it could expense as significantly as 100 yuan for file recovery, and numerous thousand dollars for repairing the challenging disk.
A large number of dollars? Just how much is often a hard drive? Repairing mechanical tough drives has high environmental and technical specifications. By way of example, probably the most simple dust-free space, this is hard to reach. Men and women who decide to repair mechanical difficult drives are often not for the tough drive, but for the information in the tough drive. The data is priceless.
Beneath we talk about some vital misunderstandings of mechanical hard drives

(Just before once more, let ’s initially recognize the internal structure from the mechanical disk. The principle elements within the hard disk would be the prototype disk and also the robot arm on this disk. The probe with the robot arm is only several nanometers from the surface in the disk. The explanation why the really hard disk is afraid of falling. When the mechanical hard disk is functioning, the magnetic disk will rotate at a speed of 5400 revolutions or 7200 revolutions per minute. The mechanical arm also performs high-speed movement on the high-speed rotating disk.
1. Try to remember that the maximum study and write operations of huge data can't be performed in the exact same time
Clarify: In the very same time, I was writing 20G of data to a tough drive, and I was reading an additional 30G of data. And all will be the maximum study and write speeds of mechanical tough drives. This time, the mechanical arm within the mechanical challenging disk jumps on the magnetic disk at higher speed, it is straightforward to scratch the magnetic disk or the mechanical arm can't be recovered. Reflected around the program is the method stuck.
SanDisk SD Card Video recovery has a deep practical experience: At first, the editor made use of Thunder to download 50g of information in to the mechanical disk at a speed of 11M / S. For the duration of this period, the editor mistakenly deleted an additional 60G of information within the mechanical difficult disk. (Since when the data is deleted, the system will scan the file to figure out the file size, which can be a high-speed disk reading approach.) High-speed disk reading and high-speed disk writing are performed at the similar time, and also the files are very significant. Immediately after about 3 seconds, the method is stuck. And also the mechanical tough disk heard a 'squeak' sound. Initially glance, the robot arm did not retract, scratching the disk. There is no method to save, and eventually 2T data is scrapped. The editor had to replace a brand new challenging drive. Please pay interest! !
two. Make sure to take anti-vibration measures
Because of the style in the mechanical difficult disk (talked about above), the distance amongst the robot arm probe plus the disk is extremely close, and it's straightforward to 'knock' towards the disk when encountering vibration. Harm to the disk. Nevertheless, the common mechanical tough disk has been fixed in spot, so long as there is certainly no 'violent' vibration, it's usually unobstructed.
three. The data transmission procedure cannot be forcibly interrupted
This is not to say that the transmission cannot be interrupted, but that it can't be 'forced to interrupt'. Forced interruption contains (use the task manager to finish the transmission process) and (sudden energy off). https://condorsugar53.webgarden.cz/rubriky/condorsugar53-s-blog/two-tricks-to-assist-you-recover , poor tracks are left on this disc. (Disks are utilized to store info rmation one track at a time. If one of the tracks is broken, it truly is named a bad track.) Terrible tracks will not be terrible. They're afraid of a large number. Terrible sectors improve with the variety of improper use of mechanical hard drives. When the quantity reaches a particular level, it is going to bring about errors around the file (file corruption, file loss, and so on.). It can also cause crashes, blue screens, etc. Commonly speaking, bad sectors can't be repaired and can only be shielded. If there's an excessive amount of shielding, there will not be considerably storage space left on the tough disk.
