Will bt download reduce SSD life?

Let's look at the difference between SSD and traditional mechanical hard drives. The following figure can be seen, the traditional mechanical hard disk by the disc, magnetic head, rotating shaft, control motor and other parts, working disc rotation, magnetic head positioning in the disc at the designated location for reading and writing operations, in a sense and the structure of the old phonograph similar. The advantages of traditional hard disk are large capacity, low cost and long life, which is suitable for large capacity data writing, but the disadvantages are also very obvious, such as large volume weight, high calorific capacity, slow speed, no earthquake resistance, high noise and so on.

As for SSD solid-state drives, it is actually made of Nada Flash. Because there is no mechanical parts, so stability, noise, calorific value, seismic resistance is better than the traditional mechanical hard drive, and also faster read and write speed. Of course, the high cost of flash memory, so the price of SSDs is also higher. Take the same 1TB capacity as an example, the traditional mechanical hard disk is only about 800 yuan, and SSD needs at least 2000 yuan.

So, what is the read-write life of SSD solid-state drives? There are also two parts to be divided. SSD flash particles are usually two particles of SLC and MLC, whereas SLC can read and write about 100,000 times and MLC only 10,000 times, so the high price of solid-state drives using SLC particles is higher.

Well, about the difference between the hard disk material we already understand, then why do we usually think that BT download will damage the hard drive? is because of BT and other Peer-to-peer downloads will be downloaded at the same time upload data, resulting in hard drive uninterrupted read and write, and mechanical hard drive because of the need for high-speed rotation, overheating will occur, the impact on the hard disk life. However, since SSD does not need to rotate, the effect of BT download on SSD is mainly focused on the reading and writing life.

Now let's take a look at the stress tests of the foreign digital media on the mainstream SSD solid-state drives to get a sense of how well their reading and writing life is going.

Techreport has been carrying out a solid-state hard drive durability test last August, including Kingston, Samsung, pirate ship and other well-known brands of the model, continued to write 200TB data, equivalent to five consecutive years to write 100GB daily, in order to evaluate their service life, the results shown in the following figure:

Health performance after continuous writing of 200TB data in mainstream solid-state drives

From the results, Samsung two solid state hard disk health is the lowest, respectively, 51% and 19%, and Kingston and pirate ship due to compatibility problems, the display of 100% health is not accurate. But even the lowest-health Samsung 840 series 250GB is still available. In terms of performance, all solid-state drives written to 200TB content are about the same as the initial level, and the worst model performance declines by 2%.

Continuous write performance changes after continuous writing of 200TB data in mainstream solid-state drives

For the average user, "five consecutive years to write 100GB daily" This operation is almost impossible, so the test results show that SSD has a very good durability and stability, to deal with the day-to-day BT and other peer-to-peer download no problem.

Of course, SSD solid-state hard disk quality and the use of particles, the quality of the main control chip are related, you can search for key parameters. In general, Samsung, Seagate, Kingston and other major brands of products have more reliable quality assurance, and provide a three-year warranty, basically do not have serious problems. In addition, we recommend that you buy in a reliable business, to avoid the purchase of fakes and refurbished goods.

Q: BT and other Peer-to-peer download method will reduce SSD solid state hard disk life?

A: First of all, the answer: basically will not have any effect.
