Hello everyone, this time to the hard drive, the first hard drive should be Quantum Fireball 2.5G, as if I have been RP has not been good, that piece of hard disk finally found to look like JS to install the second-hand goods, from taking the first home Days are innumerable bad sectors, resulting in the system often can not get in, and it is also a random crash, then the lawsuit retired the entire computer, but also to thank the JS, let me learn a lot of hardware and software knowledge, every day FDISK And LFORMAT, and then later for the computer, the hard disk seems to be there for some time is Seagate's world (like there is still some time the IBM glass hard disk is very hot?), for a few pieces of Seagate, and finally to install the machine has been Western Digital, black, blue All have been used, the green disk has not been chosen due to relatively low performance, a few years ago because of the 1T's blue disk is not enough, then it is recommended that the single-disc 1T 7200 transfer TOSHIBA, I bought a 2T TOSHIBA, later Two additional SSDs were installed, and the computer was basically on for two seconds. I thought this was safe. I did not expect the computer to enter the system very slowly every time. The hard disk had to read and write for a long time. After entering, it still lost response sometimes. Inside HDD Things often do not copy out, look at HDTUNE, 05 items about dozens of errors, C4 also dozens of, know that the hard drive is a problem, but now it is too lazy to toss, holding so much to say so much It took a few months (too lazy) and the situation became more and more serious. At first glance, it has risen to more than 1,000. It seems that there is no need to change the hard disk data. This piece of TOSHIBA should be the successor After the first piece of Quantum saw the bad road during the service period, I immediately had a bad impression on the brand, looked at the next day of purchase, just over 3 years of insurance, remembered that a user said TOSHIBA insurance It's bad, although it can't be completely generalized, but it's true that I really did it. Got it, just rest and change!
The first Quantum fireball, when 2.5GB is a very large hard disk, the game can be installed more than one.
Kill TOSHIBA
The last data, 05 items 710, C4 is 1111
I am buying things now. I don't like to compare too finely. I just bought it when I look pleasing to the eye, so I naturally think of the Western Digital again. I'm quite convinced by this brand. When Seagate came out with an XX door, she would not dare to buy Seagate. , but I have used so many pieces of Western Digital that haven’t had problems in the service period. They are finally eliminated. The brand’s trust level is like this. If you have no problem with it, you naturally trust it, but perhaps It happened that other people would encounter a lot of problems. The next time they would never choose again, just like my TOSHIBA, so it wasn't a good brand, but it just happened to me.
Western Digital's latest hard drive positioning, as shown above, it is impossible to let me connect with the XX team under the map, even the color is the same, it is also easy to remember and increase the topic degree, black disk flagship performance, I used but too Noisy, performance is still relying on SSD, so this is free, and now the blue disk is equivalent to the previous green disk, is actually 5400 rpm, all 2016 actually still retrogressive, PASS, the remaining gold is Enterprise level, no need, red disk NAS monitor disk, the price is almost doubled, no need, so there is only the purple disk, according to the positioning of the Western Digital, purple disk is a video surveillance disk, support 24 × 7, speed 5400rpm - Adjustment between 7200 rpm, there is no requirement for the performance of the warehouse, just Jingdong also hit a few fold that day and won.
Today I saw JD rise again. I got 429, so it feels okay.
In fact, many people also recommend this Seagate 2T, single-disc 1T, 7200 rpm, performance should be better.
Orders at night, delivery the next morning, JD's efficiency, as always, I hope to be able to guide nearly 1.5T data in one day.
For simple packaging, I remember that there was still a black sponge cushion on the hard drive. The warranty seems to have shortened. Is it now 2 years?
The golden fingers are all new and both are called second-hand east. I bought so many things only one charger, and the others are still very satisfied.
Originally wanted to find some of the purple disk performance data on the Internet, found that can not find, but not too cold on the performance, so I do not care, and to test their own to see how the level of this purple disk.
The average rate is 120MB/s, which is quite satisfactory. The more regrettable is that the access time is more than 20ms, which is a little bit worse than the 7200rpm product of Seagate.
Let's take a look at the old TOSHIBA, which is bad, and the waterfall curve is drunk
Random Access Test, TOSHIBA on WD (Broken)
Last ATTO chart
Originally wanted to test this ssd benchmark, but it was too slow. HDD really is not suitable for random storage. I gave up half of it.
Just pulling out a piece of SSD with normal performance is also the ultimate abuse of HDD.
Another point worthy of praise is that this disk is very quiet. Now that the computer is running and running, there is no sound and it is very comfortable. Therefore, the low speed disk also has the benefit of low speed disk. As a warehouse disk, the performance gap of dozens of M is There is no impact on the experience. I hope that it will not be broken anymore. The next time I change hard disks, I hope the time will be 500 to come to a 2T SSD.
TFT LCD screens are characterized by good development, high screen, strong sense of layering, and bright colors, but there are also relatively power consumption and low cost. TFT screen technology legendary the development of mobile phone color screens. Many of them support 65536 color displays, and even have 160,000 color displays. With a very high screen TFT, the visual advantage is important.
Technical characteristics
TFT technology was developed in the 1990s. It uses new materials and new processes for fine semiconductor all-electronic manufacturing technology. It is the basis of liquid crystal (LC), inorganic and organic thin-film electroluminescence (EL and OEL) flat panel displays. It is a variety of films made on non-single materials such as glass or plastic products (of course also on the surface) through methods and chemical reaction forming processes, and a large number of micro-integrated circuits (LSIC) are produced through the processing of the films. Non-single crystal crystals can achieve cost reduction, which is an extension of traditional small integration to large area, function, and direction. Manufacturing TFTs that control the switching performance of pixels (LC or OLED) on large glass or plastic products has a higher technical content than manufacturing complete ICs on silicon wafers. The required production equipment and production technology surpass the production of large-scale integration of semiconductors, which is the luster of modern technology. The main features are:
(1) Large area: The first generation of large-area glass products (300mm×400mm) TFT-LCD-production line was put into production at the beginning of the nineties, and the area of eye glass has been expanded to 60mm×80mm in 2000), as well as 950mm×1200mm glass The design will also run.
(2) High integration: The size of the 1.3-inch TFT chip used for the projection of liquid crystal is one million for GA. The resolution is SXGA (1280×100×1280×1000×1280×1000×1280×1000×16.1 inch TFT screen amorphous film) 50nm, and TAB ON GLASS and SYSTEM ON GLASS technology, its IC integration, The technical requirements for equipment and supplier technology are more difficult than traditional LSI.
(3) Powerful function: TFT as a matrix selection solution provides the light valve characteristics of liquid crystal. TFT-LCD is the first Liquid Crystal Display in human history whose display quality exceeds that of CRT. The function will be more powerful, which is unmatched by traditional small integrated circuits.
(4) Design: Glass products and plastic products have fundamentally solved the problem of large semiconductors and opened up potential applications for the application of small semiconductors.
(5) Ingenious process: In addition to the use of vapor phase, chemical vapor deposition (chemical vapor deposition) MCVD (molecular chemical vapor deposition) and other processes to form films, laser flame technology has also begun to be applied traditionally, not only making amorphous films, polycrystalline films, but also Single crystal films can be manufactured. Can make silicon film, can also make other II-VI group and III-V group semiconductor thin film.
(6) Wide range of application fields. Liquid crystal display based on TFT technology is a rich industry in the information society, and the technology can also be applied to the rapid growth of thin-film organic electroluminescence (TFT-OLED) flat panel Display Screen shots. .
