BT download is damaged SSD?
-SSD solid state hard drive BT download, P2P download-IT information BT download is damaged SSD?

Summary: description of the test stability of SSD is very good, P2P and BT are generally not a problem.

Q: BT P2P download way will reduce SSD SSD life?

Answer: first of all, find out: there will not be affected.

We'll see SSD solid state drive differences from traditional mechanical hard disks. By the figure below you can see that traditional mechanical hard disk platters, heads, parts such as hinges, motor control, working disc rotating, positioning of magnetic heads for read and write operations on the disc at the specified position, in a sense similar to the old-fashioned Gramophone structure. Traditional hard drives has the advantage of high capacity, low cost, have a relatively long lifespan, suitable for large-capacity data is written; but the disadvantage is obvious, such as dimensional weight, heat capacity, slow, non-earthquake-resistant, noise, and so on.

Traditional mechanical hard disk drive (left) and SSD solid state drive (right), the internal structure of

SSD solid state hard drive actually use NADA made from Flash memory. Because there is no mechanical parts, stability, noise, heat and shock resistance are better than a traditional mechanical hard disks, in addition to read and write faster. Of course, higher cost of Flash memory, SSD prices are higher. With same 1TB capacity, for example, the traditional mechanical hard disk only needs about 800 Yuan, while the SSD takes at least 2000 Yuan.

Then SSD solid state hard drive reads and writes about life? Here is divided into two parts. Usually both SLC and MLC SSD Flash particles types of particles, relatively speaking, SLC can be repeatedly read and write about 100,000 times, compared to 10,000 in MLC, SLC particles of solid state drive prices even higher.

Okay, hard materials we have figured out the difference between, then why do we think BT download will usually damage the hard drive? Because BT P2P download usually download and upload data, causing hard disk uninterrupted reading, mechanical hard disk due to high speed rotation, overheating may occur, affecting life on the hard drive. But because of the SSD does not need to be rotated, so in fact BT download SSD is mainly focused on the impact of literacy on life.

Next, we'll look at digital media abroad for mainstream SSD solid state hard disk stress test, and we can learn about their life-how to read and write. TechReport started in August last year, a solid state drive durability tests, including Kingston, Samsung, Corsair, and a variety of well-known brands selling models, continued writing 200TB data, equivalent to every year for five years to write 100GB, to evaluate their service life, the results as shown in the following figure:

Mainstream solid state drive continuous writing 200TB data health-performance

Judging from the results, Samsung's two solid state drives have the lowest health, 51% and 19%, respectively, while Kingston and pirate ship due to compatibility issues, display health-100% is not accurate. But even healthy for the lowest Samsung series 840 250GB, are still available. Performance, all written 200TB content of solid state drives, with the initial level of similar model with the worst performance or 2%.

Mainstream solid state drive writes 200TB sustained write performance data in a row

For the average user, "writes daily for five consecutive years 100GB" this operation is almost impossible, so the test result shows the SSD has a very good durability and stability, response to the daily BT P2P download is not a problem.

Of course, quality SSD solid state drive with the introduction of particles, quality master chip has, we can search for key parameters. Generally speaking, big brands such as Samsung, Seagate and Kingston products with reliable quality assurance and provide a three-year warranty, are not experiencing serious problems. In addition, suggest that you purchase at a reliable business, avoid buying a fake and refurbished goods.
