Second, from the brand point of view, each has its own advantages. Now I will evaluate the advantages and disadvantages of several common brands in the market from the perspective of an intermediate and ordinary technician.
1, Hitachi. Hitachi, the leader of the 2.5-inch hard disk market, bought IBM technology, so the notebook hard disk you see now is exactly the same as the previous IBM hard disk. Hard disk has become a major feature of IBM: durable and average performance. Advantages: good compatibility and durability. Disadvantages: high noise, high calorific value and average performance.
2, Samsung. Samsung's current market share should not be underestimated. In particular, the unique super-crystalline magnetic powder and encryption technology of Jinbao series have been threatening Seagate, another powerful competitor. Advantages: low noise, the cheapest price among similar products. Disadvantages: the power consumption is too high. At present, the power consumption of Samsung's hard disk is 5V 0.85A, which is nearly twice that of Seagate's 5V0.487A It is recommended to install it in a notebook computer, which is not suitable for mobile hard disk, because the maximum output of USB interface is 5V0.5A. Continuous loading operation will lead to data loss.
3. Seagate Seagate's large hard drives account for 70% of the desktop hard drive market. Due to poor marketing of notebook hard disk, it ranks second after Hitachi at present. Seagate's R&D strength is the strongest of its kind, and many of the same industries have used Seagate's patented technologies, such as vertical reading and writing technology and free-falling head suspension technology. Advantages: the strongest performance and leading technology. For example, the same 5400 rpm hard disk, Seagate has the lowest power consumption and the fastest speed. Disadvantages: the tray is exquisite, not resistant to falling, and requires high stability of power supply.
4. Western data. The brand was originally specialized in military industry, and later turned to the civilian market. The market share of 2.5-inch hard disk is not high, which may be due to poor marketing and low consumer recognition. Good quality, high safety factor, low in repair rate. Advantages: Super stability, 0.55A low power consumption and good noise control. Disadvantages: the disk body of Western Digital is made of special plastic. If it is BT 24-hour download, forget it. Simply put, it is suitable for mobile hard disk, not for notebook.
5, Toshiba, Fujitsu. Why do you want to introduce this brand together? There is a simple reason. Very rare in the market, mainly in notebook computers. Simply put, the power consumption is 0.6A, the performance is average, the noise is average, the calorific value is average, and the disk reading error rate is average. But because so many are average, the failure rate of this kind of hard disk is very low compared with that of repair rate, so notebook computer manufacturers especially like to use these two brands, not to mention Toshiba and Fujitsu are also experts in notebook computers. At present, big manufacturers such as Hewlett-Packard use Fujitsu hard drives, which reduces the cost because of the low repair rate, hehe.
Third, it's time to talk about hard disk boxes. Friends with a little computer knowledge should know. The so-called mobile hard disk is actually composed of an ordinary notebook hard disk and a shell with a control chip. This is true regardless of the original assembly. It's different whether it's original or assembled. Saving a machine with good accessories is more expensive than assembling a computer. In fact, this principle also applies to mobile hard disks. As for the quality, as long as you use genuine products, the quality is absolutely the same as the original ones.
Having said that, it can be summarized in one sentence: there is no best, only the one that suits you best.
In the Tang Dynasty, the river was forbidden on the shore of China, and Mu Xun was closed, and foreign countries frequently sealed it.
