This article is about what a removable hard disk in a computer refers to. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Mobile hard disk can be plugged in or unplugged at any time, compact and easy to carry hard disk memory, mainly refers to the use of USB or IEEE1394 interface. The advantages of mobile hard disk: large capacity; good compatibility, plug and play; high speed; small size, small quality; safe and reliable.

Mobile hard disk is a compact and portable hard disk memory that can be plugged in or unplugged at any time; it is a storage product that exchanges large-capacity data between computers and emphasizes portability.

The advantages of mobile hard disk: large capacity; good compatibility, plug and play; high speed; small size, small quality; safe and reliable.

The vast majority of mobile hard drives in the market are based on standard hard drives, while only a few are based on micro hard drives (1.8-inch hard drives, etc.), but the price factor determines whether the mainstream mobile hard drives are based on standard laptop hard drives.

Because the hard disk is used as the storage medium, the data read and write mode of the mobile hard disk is the same as that of the standard IDE hard disk. The mobile hard disk mostly uses USB, IEEE1394 and other interfaces with high transmission speed, which can transmit data with the system at a higher speed. As of 2009, the mainstream 2.5-inch mobile hard drives had a read speed of about 15-25MB/s and a write speed of about 8-15MB/s.

Problems needing attention in the use of mobile hard disk

(1) Mobile hard disk connection: the USB connection cable of the mobile hard disk is not only a data transmission line, but also a working power supply line for the hard disk. If the connection is too long, it will lead to an increase in resistance and data interference, so that the mobile hard disk cannot work properly, so it should be noted that the shorter the USB cable, the better, except for the original configuration, it is not suitable to connect the extension cable. Second, to connect with the computer, you should choose the USB interface on the back of the chassis (the interface fixed directly on the motherboard), instead of using the interface in front of the chassis (they are connected to the front panel by the motherboard through a lead).

(2) the external power supply of the mobile hard disk: when the mobile hard disk works, the power supply of the hard disk and the data interface is provided by the USB interface of the computer. However, when using mobile hard drives above 10GB, relying solely on USB cable to supply power to the hard disk may lead to abnormal work due to lack of power, so it is necessary to use external auxiliary power supply (DC stabilized power supply).

(3) although the mobile hard disk uses the USB interface and can support hot plug, it should be noted that in the course of use (Windows Me/2000/XP system), you must make sure that the USB interface is turned off before you can unplug the USB connection (the USB interface sign next to the mouse click date, turn off the interface), otherwise the high-speed hard disk may be damaged by a sudden power outage!
