Which mechanical hard disk reads and writes faster

Computer hard disk in addition to SSD, mechanical hard disk which is the fastest?

The brand of the hard disk is recommended to buy Western Digital, Seagate and so on.

The transfer speed of SATA hard disk is also related to the interface standard of the motherboard.

Desktop mechanical hard disk Western Digital’s blue disk performance is good, do not buy green disk. Notebook can choose Western Digital or Seagate brand. The old machine to buy attention, the hard disk SATA interface must be consistent with the motherboard SATA interface standard, high motherboard BIOS can not be recognized.

Mobile mechanical hard disk is recommended to buy Seagate, its internal hard disk interface is the SATA interface, once there is an external circuit problem, you can remove the shell, placed in the hard disk enclosure as a mobile hard disk to use

What is the fastest read/write speed of a mechanical hard disk MB/S?Which brand of mechanical hard disk is better?

Currently the fastest read/write speed of a mechanical hard drive with SATA 3.0 interface will achieve a peak data transfer rate of 800MB/s for the hard drive. hard drive brands are recommended to buy Western Digital, Seagate etc.

The internal data transfer rate of the hard disk, the internal data transfer rate is the data transfer rate between the magnetic head and the hard disk’s cache, which can be said to affect the overall performance of the hard disk is the key to the general depends on the hard disk platter speed and platter data line density. In this indicator, MB/s or Mbps is often used as the unit, which means megabits per second, and if you need to convert it to MB/s (megabytes per second), you have to divide the Mbps data by 8.

Transfer rate of the hard disk: As the most important data storage device and data exchange medium in the computer, the speed of the hard disk’s transfer rate has a direct impact on the system’s operating speed. Different types of hard disks often have very different transfer rates. Now there are three main types of mainstream hard disk: according to different interfaces can be divided into parallel port ATA hard disk (i.e. IDE hard disk), SCSI hard disk and SerialATA hard disk.

SerialATA hard drives are often referred to as serial hard drives, which use a point-to-point approach to realize the group transmission of data to bring higher transmission efficiency.

The transfer speed of SATA hard drives is also related to the interface standard of the motherboard.

Desktop mechanical hard disk Western Digital’s blue disk performance is good, do not buy green disk. Notebook can choose Western Digital or Seagate brand. The old machine to buy attention, the hard disk SATA interface must be consistent with the motherboard SATA interface standard, high motherboard BIOS can not be recognized.

Mobile mechanical hard disk is recommended to buy Seagate, its internal hard disk interface is the SATA interface, once the external circuitry problems, you can remove the shell, placed in the hard disk box to do mobile hard disk use.

Computer hard disk in addition to SSD, mechanical hard disk which is the fastest?

Originally Western Digital’s Black Disk series, now Seagate’s single-disc 1TB hard drive, with a seek time of only 10.6 milliseconds, shorter than Western Digital’s 1TB Black Disk’s 11.7 milliseconds, is the fastest consumer-grade mechanical hard drive. But after a while it’s hard to know which one it is.

Mechanical hard drive read and write speed

Mechanical hard drive is an indispensable part of the computer, can improve the computer memory running speed, can be said to be a lot of computer fanatics favorite thing. However, some computer white friends do not know the mechanical hard disk read/write speed, the following small introduction to the mechanical hard disk read/write speed.

First of all, there are various specifications for the rotational speed of a mechanical hard disk, such as: platters at 4400 rpm, 5400 rpm, 7200 rpm, 10000 rpm. The characteristics are: the higher the platter speed, the faster the read and write speed.

In addition, the performance of laptop hard disk and desktop hard disk have different differences. Some of the different manufacturers of the main control chip, there are also some differences in the impact. The size of the cache capacity of the hard disk will also have an impact on performance, read and write speed.

For example, a desktop mechanical hard drive with a 7200 capacity will typically have a read speed of about 110M, a write speed of about 90M, and an access time of about 14ms.

For example, if it’s a 3TB mechanical hard drive. The relevant test data says that the sustained read speed is 155.2MB/s speed, and the write speed is 152.3MB/s.

Also, the SSD solid state disk, because there is no mechanical rotating parts, uses flash memory chips as data storage units, that is, it uses the electric charge storage method to record the data. Its electronic efficiency is much higher than its mechanical efficiency. Its market products, random sequential read and write speed of up to 540MB/s or so. The read/write speed of the lowest-grade products can be compared with that of the highest-grade mechanical hard disks.

For example, the mainstream OCZ now has a read speed of 220M, a write speed of 200M, and an access time of only 0.01s.

Ask the gods to recommend a best mechanical hard disk 1t with unlimited price. Requires fast read/write speed. Good quality.

Western Digital VelociRaptor1TB

This is considered to be the fastest 1T mechanical inside.

10,000 rpm, 64MB cache, SATA3 interface

Expensive price, 1799, might as well change SSD
