区块链需要买多大的硬盘呢,区块链需要买多大的硬盘才能用

1. The difference between mobile hard disk 2.0 and 3.0

1. Different interfaces

1. Mobile hard disk 2.0: A mobile hard disk using USB2.0 interface.

2. Mobile hard disk 3.0: A mobile hard disk using USB3.0 interface.

2. Different speeds

1. Mobile hard disk 2.0: The maximum transmission bandwidth is 480Mbps (ie 60MB/s).

2. Mobile Hard Disk 3.0: The maximum transmission bandwidth is up to 5.0Gbps (640MB/s).

3. Different structures

1. Mobile hard disk 2.0: The interface only has 4 wires and two The power line and two data signal lines, so the signal is transmitted serially.

2. Mobile hard disk 3.0: Based on the original 4-wire structure (power, ground, 2 data), USB 3.0 adds 4 more lines for receiving and transmitting signals.

2. Are there any computer requirements for the blockchain major?

The blockchain major has certain computer requirements. Since blockchain requires a lot of calculations and data processing, it requires computers with high computing power and storage capabilities. Specifically, you need an efficient processor, enough memory, a reliable hard drive, and a high-speed network connection. At the same time, in order to support the development of blockchain applications, you need to have certain programming skills and computer science knowledge, and be familiar with blockchain technology and related development platforms. In short, blockchain specifically refers to the fact that the potato industry requires computers with certain performance and functions to ensure the effectiveness of developing and operating blockchain technology.

3. How big is the hard drive?

If it is a home computer, usually a mechanical hard drive with a capacity of 1TB to 2TB from Wcong is sufficient. If you want to improve computer performance, you can also install a 120g SSD solid state drive as a system disk.

A hard disk (English: HardDiskDrive, abbreviation: HDD) is a non-volatile memory based on rotating platters used in computers. It stores and retrieves digital data on a flat magnetic surface. The data is written to the disk by using a magnetic head very close to the magnetic surface to change the polarity of the magnetic current, and the data can be read through the disk.

The reading and writing of the hard disk adopts a semi-random access method. The data in the hard disk can be read in any order, but the speed of reading data in different locations is different.

Hard drives are divided into two types according to their working forms, mechanical hard drives HDD (HardDiskDrive) and solid-state drives SSD (SolidStateDrive). Mechanical hard disk is a traditional ordinary hard disk, which mainly consists of a platter, a platter shaft, a magnetic head assembly, a magnetic head drive mechanism, and a control circuit. solidState-of-the-art hard drive is similar to U disk technology, with an all-electronic structure and no mechanical moving parts. It uses integrated circuit storage technology and is composed of a control unit and a storage unit.
