Why is my desktop hard drive 5 inches?

Inch inch A hard drive is based on the outer diameter (diameter, in inches) of the platter.

More than 10 years ago, there were 5-inch hard disks, and the outer diameter of the platters was inches, which was convenient to call 5-inch hard disks. There's an even older 18-inch hard drive, which is bigger than a washbasin.

A few years ago, HGST (Hitachi) produced 1-inch microhard drives, and Toshiba (Toshiba) produced 1-inch microhard drives (the same size as CF cards) - these microhard disks were all knocked down by flash memory, and the inch hard disks were also in danger. Capacity** ratio, hard disk is 10 times larger than flash memory to be competitive.

Why inch, inch, inch? Because the effective recording area is just halved step by step.

Inch HDD, platter outer diameter = inch (inch).

Inch hard disk, platter outer diameter = inch (inch) - special case, there are 3 diameter inch platters used for more than 10,000 rpm hi-end, also called"Hard disk.

Inch HDD, Platter Inner Diameter Outer Diameter = ( Inch).

Inch hard disk, platter outer diameter = inches, inner diameter The specific data of the outer diameter was not found for a while.

No, there are no such big hard drives now!

Inches refer to the diameter of the disc, not to the diagonal. 2 is small, usually used for notebooks; 3 is large, usually for desktops and servers. Now the size is the same, and the mainstream ones are these two. In addition, there are 1-inch, such as micro hard drives, but they are rare.

You're either an antique, or an optical drive, or a 3-inch disc with a bracket to put it in the optical drive position.

To install a hard disk on a desktop computer, first open the case covers on both sides of the caseHow to insert the hard disk into the hard disk slot and fix it with screws, then connect the hard disk and the motherboard with a data cable, plug the power cord into the hard disk, close the case, and enter the system to set up the hard disk.

Desktop, is an independent and separated computer, completely unrelated to other parts, compared with notebooks and netbooks are larger, hosts, monitors and other equipment are generally relatively independent, generally need to be placed on a computer desk or a special workbench. Hence the name Desktop. The advantage of the desktop is that it is durable, as well as affordable, compared with the notebook, the same premise is better configuration, better heat dissipation, and the replacement of accessories if damaged is relatively cheap, and the disadvantages are:

Bulky and power-hungry. A computer is a machine that uses electronic principles to process data according to a series of instructions. Computers can be divided into two parts:

Software systems and hardware systems. The first computer, ENIAC, was born on February 14, 1946.

All the interfaces on the computer are standard interfaces, you carefully look at their correspondence, check the power cord online, don't use brute force, be gentle, you can plug it in is the right hard disk is no exception The hard disk has two wires, one is the IDE, from the motherboard to the hard disk, the other is the power cable, to power the hard disk.

Just plug in the IDE cable.

First, install 2 hard disks and pay attention to the settings on the BIOS

Second, the hard disk can be recognized on the main BIOS, it must be the problem of the first boot item, add jumpers to both hard disks, the primary and secondary disks should be separated, and the jumper positions of the two disks cannot be the same

Do you recognize it in the BIOS?,No, you change the IDE line.,Change the interface or something.。

Desktop, installed in the chassis is not easy to damage, mobile hard disk may accidentally fall to the ground.

Are you changing your hard drive? If you're the kind of desktop with a case, you buy a desktop hard drive; If it's an all-in-one and you can't unbox it, then use a mobile external connection.

1. Sudden power failure is fatal to the hard drive

2.It is also very dangerous to shake and slap the chassis when the computer is running, and it is easy to scratch the disc with the head of the hard disk, and the disc will be damaged, and the data files will be damaged and lost.

3.Hot-swappable, forced shutdown. √

4. Very frequent large-capacity reading of files, for example, you copy large files and delete files at the same time, which is easy to destroy the sector information, which is not good. √

5.It is to install the system often, sometimes the system has a problem or feels that the reflection is slow, on the pirated system recovery, this is very hurtful hard disk, it is best that the system is not often restored or installed.

6.Other aspects such as water ingress and so on hehe.

The hard drive is being used for too long.

Formatting your hard drive too many times.

The hard drive was damaged due to improper operation during installation.

The hard drive you bought is a defective or counterfeit product.

The computer has ever been infected with a virus that causes your hard drive to get corrupted (?). The hard drive has been strongly ** (or dropped).

Disassemble the mobile hard drive, and there is a SATA interface in it, see here.

Yes, as long as the system is installed, it can be used.

Yes, because they work the same way, but you'll need to buy an adapter to connect the laptop hard drive connector to your desktop.

1. Desktop hard disks are indeed much thicker, but the original meaning of this question is "notebook hard disk access to desktop" rather than "desktop hard disk access notebook", so it has nothing to do with the thickness of the hard disk.

2. The hard disk of the laptop has inches.

3. The hard disk of the desktop is used as an external hard disk, and the notebook can also be used, which requires a special mobile hard disk enclosure with an independent power supply interface.

4. Most of the speed of notebook hard disks is 5400 rpm, and there are also 7200 rpm (** relatively high), the speed is only reflected in the speed of transmission, and has nothing to do with the compatibility of mutual replacement.

Yes, but you need to install a conversion interface, because the current mobile hard disk is a notebook-like hard disk.

Theoretically, yes, but you need a corresponding conversion device, you go to the electronic city to take a look

Yes, but the interface is different.

Do laptop hard drives work on desktops.

The old hard disk with the 80G IDE interface of the inch is not available for the current machine, either the old machine from several years ago can still be used, or the easy-drive cable is used as an external hard disk. (But now the USB disk is 64g).

inch of Western Digital's hard drive.

full speed) is 12mbps, which is a small b, that is, a bit, not to mention only a theoretical speed. The conversion is bps

high speed) is 480mbps. 60 bpside: about 133 MB s.

sata:150mb/s

The theoretical speed mentioned above is actually lower.
