As we know, mobile hard disk is mainly composed of hard disk, hard disk box (or shell) and data transmission bridge circuit. Because the internal hard disk size is basically the same (for example, the volume size of a 2.5-inch hard disk is 100mm? 70mm？ 9.5mm), if manufacturers want to reduce the volume of the whole mobile hard disk, mainly in the circuit board and hard disk box. So, what exactly is the E800? Slimming? Method, thus becoming the world's smallest 2.5-inch mobile hard disk? Next, let's discuss its amazing features and? Slimming? Dafa.

Yi Jie E800 packing box is very simple and consistent with the previous product style, but this time we received a capacity of 320GB.
Product features are also clearly marked on the back of the box, such as the first domestic second-generation mobile hard disk technology product, the world's smallest 2.5-inch mobile hard disk, using JM20329 chip.

The size of E800 is about 109mm? 78mm？ 13.5mm, which is about 20mm shorter than the 2.5-inch mobile hard disk before Esay, and not much longer than a chewing gum box. Does it feel the same? Naked? 2.5-inch hard drives are not much different. For the general mobile hard disk, we can understand it as putting the hard disk into the hard disk box; For this E800 mobile hard disk, we can understand it as? Hard disk box? (In fact, it's just a layer of high-quality silicone jacket) cling to the hard disk, thus forming? Thin man? A slim figure. Some people may think that the hard disk box is different from the traditional design, and the force buffer space when the product hits is small, and the earthquake resistance will be greatly reduced. However, Yi Jie E800 is designed with anti-seismic materials imported from Germany, and has passed the two-meter anti-seismic test certification, so users don't have to worry about the anti-seismic performance of this product. The silicone jacket feels very comfortable and has a good anti-slip effect.

The second generation mobile hard disk technology is another highlight of E800. So what is the second generation technology? In fact, through JM20329 chip, USB technology is loaded on the hard disk control PCB board, directly forming USB interface output. This can not only effectively improve the transmission speed and stability, but also help to reduce the volume of the mobile hard disk (because it saves the space of PCB in the hard disk box). In addition, it can also support NCQ native instruction set technology, reduce processor occupation and improve work efficiency. This technology can be said to be specially designed for mobile hard disk. E800 is the smallest mobile hard disk at present because it is adopted for the first time.

It is worth noting that this mobile hard disk also adopts a screw-free design, which makes the whole appearance more concise. There are not many interfaces, buttons and indicator lights on the E800, and there is only one miniUSB interface at the top.

The product is equipped with corresponding data cable, but the length is short (I don't think this is necessary? Slimming? ) may not be suitable for some application environments. In addition, Yi Jie E800 also presented Kingsoft Internet Security 2008 software, and manufacturers still attach great importance to users' data security.

Test platform and software:
In the HD Tach RW test, the reading test curve fluctuated greatly at first (probably because the application of the second-generation technology was not mature enough and its advantages were not fully reflected), but it was relatively stable in the later stage. The burst speed during the test reaches 35.2MB/s, and the average reading and writing speeds are 29.4MB/s and 22.3MB/s respectively.

Because the reading and writing speed is not very fast, the test score of PCMark Vantage HDD is not very high, and the score is only 148 1.

In the physical disk test of SiSoftware Sandra 2008, the test curve of Yi Jie E800(320GB) is similar to that of HD Tach RW.

In the reading test of HD Tune Pro 3.00, the front end of the test curve of Yi Jie E800(320GB) still shows great fluctuation, and the average reading speed is 29.1MB/s. ..
The average seek time of E800(320G) is 20.2ms, which is slightly higher.
In the FastCopy file copying test, we copied about 23GB files to E800(320GB), which took nearly 32 minutes. The transmission rate 12. 14MB/s is a bit slow.
In ATTO synchronous reading and writing test, the hard disk reading and writing performance reached the highest level after reaching 64K cluster, and the data score reached the peak. The synchronous reading and writing performance of this mobile hard disk is relatively stable. The maximum reading and writing speed is about 26. 1MB/s and 35 MB/s. ..
CrystalDiskMark 2.2 is a compact tool for testing hard disks or storage devices. The reading and writing speeds of this test object are 10.58MB/s and 1 1.44MB/s respectively. It is worth mentioning that Yi Jie E800 adopts FDB automatic hydraulic roller balancing technology and wireless floating GMR head design. During the whole test, this mobile hard disk runs very quietly.
"Yi Jie E800(320)
"Reference quotation:
"599 yuan.
"Advantages: small size, comfortable feel, and the second generation technology is adopted for the first time.
"Disadvantages: slow transmission speed.
Products that are ahead of development can often attract our attention, and this E800 mobile hard disk is no exception. The second generation mobile hard disk technology is the most worthy of our attention. Although the transmission performance has not fully reflected the advantages in this test, it has a certain effect on reducing the product volume. I believe this technology will be adopted by more products. E800 mobile hard disk is still very suitable for users who pay attention to product size and large-capacity mobile storage.
