Hello, you can take high-speed rail bus line 2 to the urban area. I don't know where you are going to the urban area, so this bus is your best choice. Qiushui Square is also very prosperous
bus line: High Speed Rail bus line 2, the whole journey is about 13.3km
1, walk about 10m from Nanchang west station to Nanchang west station
2, take high speed rail bus line 2, pass 3 stops, reach Qiushui Square Station
3, walk about 810m to Nanchang city
2. It depends on how fragmented you are
if it is scattered, it can be increased by about 20%< However, it is estimated that the average person is less than 10
once every three months or half a year, the effect is not bad, it will be more convenient to use...

5. To improve the writing speed, you can only replace it with a better hard disk. For example, Samsung's popular solid-state drive can write more than 3000 + m, which is already very fast.

7. Transmission rate of hard disk: as the most important data storage device and data exchange medium in the computer, the speed of hard disk transmission directly affects the running speed of the system. Different types of hard disk, the transmission rate is often very different. Now there are three main kinds of hard disks: parallel ATA hard disk (IDE hard disk), SCSI hard disk and serial ATA hard disk according to different interfaces
IDE interface hard disk is the most widely used in current computers. The mainstream specifications include ATA / 66, ATA / 100 and ATA / 133. This naming method also shows that their theoretical maximum external transmission rates are 66mb / s, 100MB / s and 133mb / s respectively. It should be noted here that 100MB / s and 133mb / s are peak speeds, which does not mean that the hard disk can maintain this speed, that is to say, it is the highest peak speed in theory
the real transmission rate of hard disk is affected by the internal transmission rate of hard disk, and its stable transmission rate is generally between 30MB / s and 45Mb / s. Thus, with the continuous improvement of CPU, memory and other hardware running speed, the low speed rate of ATA hard disk has graally become the bottleneck affecting the running speed of the whole machine. Therefore, a new way of hard disk interface, serial ATA, came into being
serial ATA hard disk is what we often call serial port hard disk. It uses the point-to-point method to realize the packet transmission of data, which brings higher transmission efficiency. The initial transmission rate of serial ATA version 1.0 hard disk is 150MB / s, while serial ATA version 3.0 will achieve the peak data transmission rate of 600MB / s, so as to finally solve the system bottleneck problem of hard disk
SCSI interface is not specially designed for hard disk. In fact, it is a bus type interface and works independently of system bus. The hard disk with SCSI interface is widely used in servers and professional workstations for its high stability and low CPU occupancy. Its transmission rate can reach 320mb / s. Of course, for the overall performance of the hard disk, in addition to the transmission rate of the hard disk, the speed, cache and average seek time of the hard disk are also important factors< The internal data transfer rate of the hard disk is the data transfer speed between the magnetic head and the cache of the hard disk, which can be said to be the key to affect the overall performance of the hard disk. It generally depends on the disk speed and data linear density of the hard disk. In this indicator, MB / s or Mbps is often used as the unit, which means megabit / s. if you need to convert to MB / S (megabyte / s), you must divide the Mbps data by 8. For example, some hard disks give a maximum internal data transfer rate of 240mbps, but if calculated by MB / s, it is only 30MB / s. From this we can see that the current hard disk as the bottleneck of the computer, its root cause lies in the internal data transmission rate of the hard disk
2. The external data transfer rate of the hard disk
refers to the rate of reading data from the hard disk buffer. It is directly linked to the interface type of hard disk, so it is often replaced by data interface speed in advertisement or hard disk characteristic table, and the unit is MB / s, as we usually call ata100 / 133 hard disk
transmission rate of optical drive: generally, the transmission rate of optical drive depends on the multiple speed of optical drive, such as 16x DVD and 52X CD-ROM. generally, the higher the multiple speed of optical drive, the faster the data transmission. So what is the concept of "double speed"? Long ago, the transmission rate of CD-ROM was very low. It could only transfer 150kb bytes per second. That is to say, the original speed of CD-ROM drive was 150kb / s, which was called the 1 x (single speed) CD-ROM drive. Later, with the rapid development of CD-ROM drive technology, its speed is faster and faster. In order to distinguish different speed optical drives, the initial 150kb / S is used as the benchmark to measure and get the corresponding speed multiplier value. For example, a 50x CD-ROM means that its transmission speed is 50 times that of a 1x CD-ROM drive, that is, its speed is 50 × 150KB/s=7500KB/s Now the popular rate algorithm of DVD-ROM is basically the same, but the single rate of DVD-ROM is much higher than that of CD-ROM. theoretically, the speed of double speed DVD-ROM can reach 1358kb / s, so we can calculate that the speed of popular 16 speed DVD-ROM should be 1358kb / s × 16=21728KB/s

today's hard disk is about 50-150m per second

9. This has a lot to do with your hard disk. Those old hard disks with 7200 RPM parallel port can only write 23m and read about 20m when tested by the optimization master. If the serial port is 7200 rpm, the 8m cache can read 56m and the read is 52m
the read / write speed of hard disk is related to many factors, such as speed, single disk capacity, serial port or parallel port, cache, etc
