The difference between 5200 rpm hard disk and 7200 rpm hard disk is not big, such as Internet access, booting, etc.?
The index refers to the number of revolutions per minute of the hard disk. The faster the speed, the faster the hard disk looks for files, and the relative speed of the hard disk is improved. The speed of the hard disk is expressed in revolutions per minute. The unit is expressed as RPM. The 7200-rpm hard disk is obviously faster than 5200 rpm in data fast transmission and storage speed, but the same, higher power consumption, generally not suitable for thin and light products.
Rotationl Speed is the rotation speed of the motor spindle in the hard disk, which is the maximum number of revolutions that the hard disk can complete in one minute. The speed of the speed is one of the important parameters to indicate the grade of the hard disk. It is one of the key factors determining the internal transmission rate of the hard disk, which directly affects the speed of the hard disk to a large extent. The faster the hard disk speed, the faster the hard disk finds the file, and the relative hard disk transmission speed is improved. Hard disk speed is expressed in revolutions per minute. The unit is expressed as RPM. RPM is the abbreviation of Revolutions Perminute, which is transfer/minute. The larger the RPM value, the faster the internal transfer rate, the shorter the access time, and the better the overall performance of the hard disk.
The spindle motor of the hard disk drives the disk to rotate at a high speed, generating buoyancy to float the head above the disk. To bring the sector of the data to be accessed under the head, the faster the speed, the shorter the waiting time. Therefore, the speed determines the speed of the hard disk to a large extent.
The average hard disk speed of a household is generally 5400 rpm and 7200 rpm. The 7200 rpm high-speed hard disk is also the first choice for desktop users. For notebook users, it is 4200 rpm and 5400 rpm, but the 7200 rpm notebook hard disk is more in the market. Server users have the highest performance requirements on hard drives. The SCSI hard drives used in the servers are basically 10,000 rpm, and even 15,000 rpm. The performance is much higher than that of household products.
What is hard disk formatting? How to recover data after formatting?
When using a computer, we often need to format the computer hard disk for different reasons, sometimes it is a mistake, sometimes it is a partition prompt format, sometimes there is a virus in the hard disk partition, then, for the hard disk format How to solve the problem of data loss caused by theization?
First clear: What is hard disk formatting?
Hard disk formatting is generally divided into advanced formatting and low-level formatting. The low-level is generally working on the track of the hardware. Normal users will not touch this step because most of the time we use advanced formatting. .
Advanced formatting can be divided into quick format and normal format. Quick format is to clear the file allocation table, so that the system can not find the file on the disk after automatic detection, and does not really format the entire disk. Ordinary formatting is to scan the disk on the computer, clear all the contents of the disk, and can not recover. At present, most of the situations that people encounter are quick format. For lost data, you can use data recovery software to recover.
You can search for software on the website, but many of them are pirated and need to be identified. You can also download the software from the official website. This software can be used directly after installation and activation. Then follow the steps to do it.
The specific graphic tutorial is as follows:
1. Select the media type: Hard Drive.
Select media type

2. Select the volume label to be scanned: C drive.
3. Select Recovery Scene: Restore the formatted media.
Restore formatted media

4. Check your options.
5, save the file: the software will quickly scan the disk of the lost file, but because the disk is completely formatted, if the disk memory is too large, the scan time will be relatively long.
Data recovery software is very simple to operate and scans are very fast. Easily help users complete the data recovery work of hard disk formatting to avoid loss caused by data loss. For more related questions, please check: Hard Drive Data Recovery.
