How many times can a hard drive be written? What is the number of writes in a typical hard disk?

BT will hurt the hard disk because the developers of BT make full use of the network bandwidth, and make reasonable use of all the bandwidth of upload and ** to share the tasks of the server, this principle as long as you understand the working principle of BT yourself.

However, the author omitted the consideration of the hard disk cache when developing BT, so when using BT, the hard disk is repeatedly read and written, which will make the temperature of the hard disk continue to rise, and repeatedly in this way, it will directly lead to a great shortening of the service life of the hard disk

Therefore, the use of BT will hurt the hard disk, but now the BT software has considered the cache, and the damage to the hard disk has been reduced to a minimum, and it will generally not have fatal damage to the hard disk, although the hard disk that uses BT will break faster than the hard disk that does not use BT, but it will not be outrageously fast, so as long as it is not used for a long time, there will be no additional damage to the hard disk, because the hard disk will have a service life

The so-called damage to the hard disk means that the hard disk workload is very large when you use BT, and the life of the platter is affected by reading, reading and writing all the time, maybe the head will occasionally fall and break the platter when reading and writing: d But even think that buying a hard disk is used, so be careful not to buy a computer.

Let's calculate an economic account: **A TV series (such as: 70 episodes of Dachangjin) takes 3 days, and 121 can be played in 365 days a year, 121 * 70 = 8470 episodes, even if you use your 80g hard disk for a year, it will be 450 yuan.

450<6351, or BT is cost-effective.

BT damages the hard drive to the same extent as it does in the book. In addition, the current BT software has taken into account the problem of caching. So don't worry too much.

If you want to be more protected, put the BT file ** into the NTFS format hard disk, **cut the file to another partition after completion, and then cut it back, ** when the file fragments are gone, and the head will not frequently look for the road when reading these files in the future. Every time you do this, there will be less disk fragments, and the head will be much less able to read and write, and the life will naturally be extended.

The principle of a mule is the same as that of a bt, but a mule is of a universal nature. The ** that goes to the mule can find and** very old things, and the BT to** the hot things of the recent fashion are also very fast because of the large number of people. The old stuff bt can barely get down.

Millions of times.

The number of times you can do it is unlimited. Lifespan is related to time.

One of the indicators of hard disk is MTBF (Mean Time Before Failure). Basically, it can be seen as lifespan.

1. Generally, the average failure time of home hard drives is 600,000 hours.

2. Server hard disk, usually more than 2 times that of household hard disk. That's 1.2 million hours.

3. If it is a solid-state drive, the life is calculated based on the amount of writes. Generally, about 128G, an average of 40G data is written per day (ordinary users can't reach it at all), and it can also be used for more than 20 years.

It's about 30,000 times the so-called BT bad hard drive. Yes, it is true. However, just set the bt buffer to be larger. Reduce the speed of ** and upload a little. This will allow the drive to last a little longer. Hehe.

It's hard to say accurately!

It is mainly related to the density of use, the use environment, and the quality of the hard disk.

Generally, there is no upper limit to the number of hard disk writes, and its life is the life of the internal optical disk, whether it is a mechanical disk or an SSD. The lifespan of a hard disk drive is calculated in hours. Typically 500,000 hours.

The lifetime of an SSD is calculated by the number of writes, regardless of the number of writes. The larger the capacity, the longer the lifespan of the SSD.

SSDs use NAND flash memory as the storage medium, so there will be a write time cap. The full write is called PE, and the lifetime of flash memory is measured in PE, and the life of a 34nm flash memory chip is about 5000 times that of PE, and the life of a 25nm flash memory chip is about 3000 times that of PE.

With the improvement of SSD firmware algorithms, the new SSD can provide fewer unnecessary writes. A 120G SSD can only be used as a pee when writing to a 120G file.

HDD has no write limit, and the lifespan is the life of the disc inside, which is ten years.

The SSD uses NAND flash memory as the storage medium, so there will be an upper limit on the number of writes, and NAND is divided into two categories: SLC and MLC, the former can write up to 10W times, relatively speaking, ** will be much higher, only enterprise-level SSDs will be used (such as Intel's 720 series), and the latter cost is relatively low, so the number of writes will be reduced accordingly, and the latest particles in the SSD using MLC on the market are 25nm process, The number of writes is only 3k times, while the older SSD uses a 34nm process, and the number of writes can reach 5k times, but there is a certain gap between performance and power consumption (especially power consumption) compared with 25nm.

There is no such limitation, and the life of the hard disk mainly depends on the model and batch of the hard disk, as well as the usual maintenance.

Solid state drives are available on the market today.

and mechanical hard disks, the life of the two is different.

1. Solid state drive.

The standard for judging the life of solid-state drives is generally the number of writes or write capacity, and the calculation of write capacity units is not intuitive, among which there are 4k and 8k random write capacity.

The role of the flash memory medium is to allow the integrated circuit to replace the platter, write and read the data through continuous charging and discharging, and complete the data exchange through the main control chip. SSDs do not have a simple mechanical structure and do not require seeking, so the read and write speeds are much faster than HDDs.

However, due to the limited number of charging and discharging of flash memory chips, every time you read and write, it is a process of charging and discharging, so the life of the SSD is mainly affected by the number of reads and writes, and the capacity.

Depending on the type of flash memory chip (SLC, MLC), SSDs can read and write 1-100,000 times, and professional-grade SSDs can reach 1-100,000 times, and the shortest service life can also reach 5-10 years.

2. Mechanical hard disk.

Mechanical hard disk is more like the working principle of optical drive, there are hard disk platters (similar to optical discs), motors that drive the platter to rotate, magnetic heads, belonging to precision mechanical devices, the working principle is to find information on the high-speed rotating platter through the magnetic head, to complete the data exchange work, it is completely a closed optical drive. If the mechanical structure is not maintained, it will also be "fatigue", so the mechanical hard disk will be used for a long time, there will be noise, seek time becomes longer and other problems, the life of the mechanical hard disk is generally calculated by years, generally more than 3 years or 5 years, so many hard disk manufacturers are guaranteed for 3 years or 5 years. Of course, more than 3 years does not mean that the hard drive cannot be used.

HDD has no write limit, and the lifespan is the life of the disc inside, which is ten years.

The SSD uses NAND flash memory as the storage medium, so there will be an upper limit on the number of writes, and NAND is divided into two categories: SLC and MLC, the former can write up to 10W times, relatively speaking, ** will be much higher, only enterprise-level SSDs will be used (such as Intel's 720 series), and the latter cost is relatively low, so the number of writes will be reduced accordingly, and the latest particles in the SSD using MLC on the market are 25nm process, The number of writes is only 3k times, while the older SSD uses a 34nm process, and the number of writes can reach 5k times, but there is a certain gap between performance and power consumption (especially power consumption) compared with 25nm.

The general HDD does not have a write limit, the life is the life of the disc inside, generally ten years and the SSD due to the use of NAND flash memory as the storage medium, so there will be an upper limit of the number of writes, and NAND is divided into SLC and MLC two categories, the former can write up to 10W times, relatively speaking** will be much higher, generally only enterprise-level SSDs will be used (such as Intel's 720 series), and the latter cost is relatively low, so the number of writes will be reduced accordingly, The latest particles in the SSD using MLC on the market are made of 25nm process, and the number of writes is only 3K, while the older SSD uses 34nm process, and the number of writes can reach 5K, but there is a certain gap between performance and power consumption (especially power consumption) compared with 25nm.

In addition, this number is only a theoretical value, because NAND particles have a certain probability of writing errors, this probability will increase with the increase of the number of writes, and as long as a piece of NAND scraps the entire SSD can be thrown away, so there will be an algorithm to evenly disperse the written content to all the particles to avoid some particles writing too heavy load, in other words, the larger the capacity, the longer the life of the SSD.

However, the general civilian SSD actually doesn't need to consider the life of much, because before reaching the upper limit of writing, it may have been replaced by you for another piece, my Micron M4 64G bought a month and a half The overall number of writes is only 4 times, according to this calculation, it takes more than 90 years to write at this speed to reach the theoretical upper limit! So you say you need to worry.

There is no limit to the number of reads and writes on the hard disk.

Whether mechanical or solid-state drives.

The life of a hard disk is measured in hours. Typically 500,000 hours.

The life of an SSD is accumulated by the number of writes. It has nothing to do with the number of times.

..There is a limit on the number of repeated writes, generally 10-1 million times, so the hard disk has no such limit?..The disk is not touching, so there is no possibility of damaging the disk.

Before the hard disk is scrapped, it is not calculated in this way, it is based on how much time it takes to read and write continuously! Tens of thousands of hours can be used (ps: refers to the cumulative time, the hard disk is not read and written).

I've tried using an old hard drive, and I've been using it for two years, and the hard drive doesn't work

Theoretically, it is more than 50,000 times, and a well-protected Seagate hard disk can last for about 10 years, and you can see a lot of information about the hard disk on the Seagate official website.
