This article introduces some information about mobile hard disk, including its features and damages.
Mobile hard disk is a portable storage gear used for storing massive computer data.
Considering price, the mainstream mobile hard disk is based on the standard notebook hard drives.
In addition, the mobile hard disk read-write mode is equal to the IDE mode.
Mobile hard disk uses USB, IEEE1394 and other interfaces to quickly transfer data.
In addition, it is not very expensive.
And, the capacity of mobile hard disk can reach 12TB.
Therefore, this kind of storage rig has been widely accepted by the public.
Besides, there is desktop mobile hard disk whose capacity is 4TB.
With the development of technology, the capacity of mobile hard disk will get larger and larger.
Small Size
Mobile hard disks come in different size, including1.8 inch, 2.5 inch and 3.5 inch.
Mobile hard disks usually use USB interface whose function is not very well.
And actually the 2.5 inch disk is different from the hard disk that notebook uses.
The starting current of notebook is about 900mA, while mobile hard disk needs 700mA.
3.5inch hard disks use desktop computer hard drives.
Although it has external power supply and cooling fan, its volume is relatively large.
High Speed
Mobile hard disk uses USB, IEEE1394 and other interfaces to quickly transfer data.
Some monitors also provide USB adapters, and USB interface is the essential PC interface.
But, larger capacity hard disk like 160G disk needs external power supply since its high rotation property.
Reliability
The security of mobile hard disk is the topic everyone concerns.
Mobile hard disk has won over many users since its high-speed, large capacity and convenience.
But, its greatest advantage is that it can ensure data security.
This kind of disk adopts silica discs that provide large capacity and reliability to improve data integrity.
Hard drive, made of silicon-oxygen, makes USB has a high reliability.
Besides, it provides shockproof function to prevent disc being damaged.
As a result, the head cant read and write data normally.
Comprehensive Damage
Comprehensive damage mainly refers to the problems brought by some minor changes.
Physical Damage
Hard disk physical damage is resulting from collision, head disk friction and other reasons.
