Q: Will BT and other P2P download methods reduce the life of SSD solid state drives? A: First of all, the answer is: basically there will be no impact. Let's take a look at the difference between SSD solid state drives and traditional mechanical hard drives. From the figure below, you can see that traditional mechanical hard drives are composed of disks, heads, shafts, control motors and other parts. When working, the disk rotates and the head is positioned at the specified position of the disk for reading and writing operations. In a sense, it is similar to the structure of an old phonograph. The advantages of traditional hard drives are large capacity, low cost, and relatively long life, which are suitable for large-capacity data writing; but the disadvantages are also very obvious, such as large size and weight, high heat generation, slow speed, no shock resistance, high noise, etc. As for SSD solid state drives, they are actually made of NADA flash memory. Since there are no mechanical parts, the stability, noise, heat generation, and shock resistance are better than traditional mechanical hard drives, and the reading and writing speed is also faster. Of course, the cost of flash memory is higher, so the price of SSD is also higher. Taking the same 1TB capacity as an example, a traditional mechanical hard drive only costs about 800 yuan, while an SSD costs at least 2,000 yuan. So, what about the read and write life of SSD solid state drives? This is divided into two parts. SSD flash memory particles are usually SLC and MLC particles. Relatively speaking, SLC can be read and written repeatedly about 100,000 times, while MLC is only 10,000 times, so SSDs with SLC particles are more expensive. Well, we have already understood the difference in hard disk materials, so why do we usually think that BT downloads will damage hard disks? It is because P2P downloads such as BT usually upload data while downloading, causing uninterrupted reading and writing of the hard disk, and mechanical hard disks will overheat due to the need for high-speed rotation, which affects the life of the hard disk. But since SSDs do not need to rotate, in fact, the impact of BT downloads on SSDs is mainly concentrated on the read and write life. Let's take a look at the stress tests conducted by foreign digital media on mainstream SSD solid state drives, so that we can roughly understand their read and write life. TechReport has conducted a solid state drive durability test since August last year, including models on sale from many well-known brands such as Kingston, Samsung, and Corsair, and continuously wrote 200TB of data, which is equivalent to writing 100GB every day for five consecutive years, in order to evaluate their service life. From the results, the health of Samsung's two SSDs is the lowest, 51% and 19% respectively, while Kingston and Corsair's 100% health is not accurate due to compatibility issues. But even the Samsung 840 series 250GB, which has the lowest health, is still usable. In terms of performance, all SSDs after writing 200TB of content are almost the same as the initial level, and the performance of the worst model has not dropped by 2%. For ordinary users, "writing 100GB every day for five consecutive years" is almost impossible, so the test results show that SSDs already have very good durability and stability, and there is no problem in dealing with daily P2P downloads such as BT. Of course, the quality of SSD solid-state drives is related to the quality of the particles and the main control chip used. You can search for key parameters. Generally speaking, products from big brands such as Samsung, Seagate, and Kingston have more reliable quality assurance and provide a three-year warranty, and basically no serious problems will occur. In addition, it is recommended that you buy from reliable merchants to avoid buying fakes and refurbished goods.
