Does the hard disk of mining machine write big data

1. This depends on what type of server you have. If it's a data server, the read-write capacity of data transmission will be larger. If it's an intranet server within an enterprise, such as OA system, the read-write capacity will be very small. However, the only advantage of using a hard disk with strong read-write capacity on the server is that the price is a little higher

2. Let me first talk about the role of hard disk cache:
when the cache value of the hard disk is large enough, the hard disk does not need to read and write to the disk frequently. On the one hand, it can prolong the life of the hard disk, and on the other hand, it can improve the data transmission speed<

according to what you said:
often download movies, sometimes BT, electric donkey and Xunlei are all on.
and there are optical cables at home, which often reach the download speed of 3MB / s and upload speed of 1.5mb/s
so the hard disk light is always on. In order to protect the hard disk, we have to limit the speed of use.

it must be better to have a large cache, So I recommend that in the case of sufficient funds, we should choose

the latter

3. However, this high load operation can last for a long time. In addition, if you write big data frequently and encounter it carelessly, it is easy to scratch the disk and cause physical damage ring operation Generally, solid state hard disk is used as system disk and mechanical hard disk is used as storage disk

4. A 5400 RPM hard disk can easily reach 50 MB / s, while a 7200 RPM laptop hard disk can also reach 60 MB / s

5. No, as long as the replication process does not vibrate, the temperature does not rise too high, a over and sub almost.

6.

The write speed and read-write speed of mechanical hard disk are about 120MB / s, the speed of solid-state hard disk based on SATA protocol is about 500MB / s, and nvme protocol (pcie3.0) is better × 2) The speed of SSD is about 1800mb / s, nvme protocol (pcie3.0 × 4) Its speed is about 3500mb / s

mechanical hard disk is mainly composed of disk, head, disk shaft and control motor, head controller, data converter, interface, cache and other parts

extended data

capacity of hard disk: the capacity of hard disk is in megabytes (MB) or gigabytes (GB), 1GB = 1024MB, 1TB = 1024gb. But hard disk manufacturers usually take 1g = 1000mb in nominal hard disk capacity, so the capacity seen in BIOS or when formatting hard disk is smaller than manufacturer's nominal value

the capacity index of hard disk also includes the single disk capacity of hard disk. The larger the capacity of a single disk, the lower the unit cost and the shorter the average access time. The mainstream hard disk is 500g, and the high-capacity hard disk above 750g has also begun to be popular

7. This & quot; Write at least & quot;, I've never seen such a term before. In fact, the writing strategy of hard disk is very scientific. Even reading and writing of large and small files can be arranged very efficiently

for example, when the current large file reading task is not completed, the queue enters the continuous writing task of small files. At this time, the small files will be filled into the cache first to ensure that the large files are completed first, It takes more time to transfer the cached data to the hard disk.

the amount of data to be written is arranged according to the demand. For example, when the hard disk is empty, you give it a 1KB write, and it will do it immediately. When it is full, it will not be able to write 100MB tasks. You need not consider the floppy disk, which is too slow

8. Of course not. If you write so much data at one time, the hard disk may run hot, such as the motor. But this is generally within the normal range. Even if you access a large amount of data every day for a long time, you can persist for a long time.

9. Read more than write when playing games ------

because you are before playing online games. Has several G large online game program installed to the hard disk
when installing the game. Write rendant read
later, when playing games. Read more than write
when you are playing games. The game scene you see on the monitor, and the characters. Whether it's a static picture or a character
it's also a dynamic character. The sound of the game and the music of the game are all read and called from your computer's hard disk
these pictures and sound tracks are stored in the game folder on your hard disk
because of so much data, it is unrealistic to read and call from the network. One is that the existing network speed can't reach, because the amount of data is too large. Moreover, if tens of thousands of users call game pictures and sounds from the network server, the server would have been paralyzed
in addition, these scenes, sounds and music are relatively fixed. There is no need to call read from the network, even if the change is small. If it changes. Before you play the game. Will let you update the game. Install small patches

when you play online games and walk inside, the picture keeps changing. These are all images read from the hard disk
the game characters you see are also changing. Your character position in the game is also changing. These changes are regarded as points and represented by coordinate data. The coordinates of these points are transmitted to the server. Most of our computers are connected to the server. We all transmit our own coordinates to the game server, and download the coordinates of the other person you can see in the game
these coordinate data are very small. Nothing more than x, y two data, the result is SD game. It's XYZ. Three data
you don't walk in the game map. The coordinate data will not change
examples. You're in the middle of the game map. So your coordinates are x (0), y (0), and you're going up to the right. That's x (1), y (1). If you walk one space from the middle of the map to the top, the coordinates are x (0), y (1). When you walk in the game. Your computer instry sends these data to the game server synchronously. Other players know your coordinates from the game server and download them to their own computers. Then it is displayed on his computer, and the pictures of the game characters are called from his hard disk and displayed on his monitor

finally, answer the supplementary questions
read and write more when browsing web pages. It depends on the size of your temporary folder. In the browser menu - tools - Internet Options - browsing history settings - temporary Internet files, there is a disk space to be used. You can adjust the size if it is smaller. Every time you browse a web page, you have to delete the data and write in new data. If the data is adjusted too large
after a lot of data is written. It will last for a long time. If the screen to be called is in the temporary folder. It will be retrieved directly from the temporary folder in the computer's hard disk. The call is not downloaded from the network. That's why it's faster to set the browser's temporary folder larger. Because many of the pictures you have browsed before, if you browse the previous page again, many of them are read from the local hard disk
the summary is: the size of temporary file settings. Read more than write. The premise is that you often visit relatively fixed websites
if the adjustment is small. So I write back more than I read
as for browsing the web or playing games, which is less harmful. It depends on how you use it.
you use the computer, either to read or to write., When you look at the text of a web page, you don't change the page for a long time. Then the hard disk won't read or write. At this time, the hard disk does not have many big tasks, do not read or write. It does less damage to the hard disk
if you play games. Just stay in a map area of the game. The hard disk doesn't have many tasks. Do not read and write
and the damage is less
if you want to rece the damage of hard disk, you'd better choose a hard disk with a large cache when you buy a hard disk
configure your computer with as much memory as possible
usual attention: do not shut down illegally. If you don't need to download BT, thunderbolt and other software for a long time, you should also set the "hard disk cache" in the software settings larger. This will rece the damage to the hard disk
do not use the computer in the environment with unstable voltage
do not let the hard disk too close to the large magnetic field, such as the subwoofer of the speaker. Better stay away
do not move the chassis while the computer is on
in general. When the hard disk is working. Writing is more harmful than reading

10.

Generally, there is no upper limit for the number of hard disk writes, and its life is the life of internal optical disk, whether it is mechanical disk or solid-state disk. The service life of mechanical hard disk is calculated by hour. Half a million hours

the lifetime of SSD is accumulated by the number of writes, and has nothing to do with the number of writes. The larger the capacity, the longer the service life of SSD

SSD uses NAND flash memory as the storage medium, so there is an upper limit of write time. Full write is called P / e. the lifetime of flash memory is in P / E unit. The lifetime of 34nm flash memory chip is about 5000 times of P / E, and that of 25nm flash memory chip is about 3000 times of P / E

with the improvement of SSD Firmware algorithm, the new SSD can provide less unnecessary write operations. 120g SSD can only be used as P / E when writing 120g files

extended data:

each sector of SD can be rewritten 100000 times (SLC), but some applications (such as operating system log) may read and write a sector many times. In this case, the actual life of the SSD has not been tested

however, through the management of the equalization algorithm, the life expectancy of the storage unit will be extended. The write life of SLC is 100000 times, that of low-cost MLC is only 10000 times, and that of low-cost TLC flash memory is 500-1000 times worse
