Xiao Bian Note: The National Day submission value turns and sends you iPhoneX! From now to October 9th, all submissions can be awarded 1.5 times the basic monetary rewards, high-quality articles can win Apple, BOSE QC30 top noise canceling headphones, Kindle Voyage and other physical prizes, the original innovators are not afraid of not take: training The hot start of the camp, Xiao Bian gave you a small stove, there are exclusive benefits, daily red envelopes, etc., how can such a value be missed, Meng Zhao activities notice, training camp number. Recently, due to various requirements, a series of pick-ups and use of storage devices began. In the process, some knowledge of this direction was gradually accumulated. Baidu's information was not timely. The update, so decided to share every device in the aunt's home. In fact, it has been bought for a long time. It has not been opened, because it is the first time to dedicate it to Aunt Zhang. Finally we celebrated the 8-day National Day holiday. There are additional rewards and we have to step up and use the evaluation. This time brought in two products that were combined and used as a mobile hard disk. SEAGATE Barracuda Series 3TB 7200 RPM 64M SATA3 Desktop Machine Hard Disk (ST3000DM008) At the time, Jingdong sold 549 yuan, plus a mother's 10-yuan full-price coupon, and invested 539 yuan. The disappearance of network disks, and the demand for networks, and some content is either shielded, or need to spend money to buy space, so the demand for hard drives is getting bigger and bigger, and the files are really more important than money. Recall that the "WanaCrypt0r 2.0" worm at that time attacked some domestic universities, and as a result, many people's graduation designs were lost. This is life. Chinese translation is to cry, people who really cry will cry. This did not catch up with the discount and purchased it for 99 yuan. There are already four transparent devices in the booth for ORICO's homes, namely the 3.5-inch mobile HDD enclosure, the 2.5-inch mobile HDD enclosure and the 4-port USB hub+2.5/3.5 hard drive base enclosure. It has to be said that it looks like it is exquisite and it really works. In order to spend some quality silver, value. This is a cool fish package. It feels great to hold it, because it is too heavy. Strong cargo? New logo The side is the ID number and related information. On the back you can see the physical photos and the manufacturer's address. Two-dimensional code of the world. 2 year warranty, insurance information is good. There is a sticker at the opening and it can be seen that it is not used. After opening, it is very simple and there is a thin layer of sea, praise. Disposable packaging should be dustproof? This is not a problem with anti-dust or anti-dust. The 3.5-inch hard drive is anti-build. Should be inherent product information. On the back, circuit boards and data lines are readily available. Protection is not bad. The interface is the same. This has finished drying, is a cold hard drive. Next is the hard disk box. EASY YOUR PC, this slogan is simple but not simple. Similarly, under the package, there is product information. It is not marked as transparent. Product features: 5gbps+3.5HDD+usb3.0+tool-free Re-emphasize usb3.0. Open, is a transparent box, very large, used 2.5in mobile hard disk, feel this big, big. All content, data cable, power supply, manual, hard disk box. 12V2000mA output. The whole line is engraved with unknown text. Blue, 3.0 Always think, why not popularize type-c, but use this kind of two? Is transmission fast? The hard disk cartridge body is covered with a transparent plastic wrap that resembles a cling film. You can see the components inside. Remove the plastic wrap. Positive logo Components Once from left to right, it is the power socket, data line socket, switch A cushion at the bottom of the box. In the beginning, it was intended to be violently dismantled. As a result, the instruction manual was taken away. . The data socket is right, so push it and it will be installed. After closing, this is actually the back This is positive because the data transmission indicator is on this side. Beauty and ugliness, a thousand people have a thousand Hamlet. A storage product, the main thing is speed. stability. Connect the power supply, plug in the data cable and press ON. I can't find it on my computer. What ghost? So this computer right-click manages disk management. Immediately jump out and identify the new storage device, you need to determine the format. The following notes that all early-rising versions of Windows are not GPT-partitioned. I thought, this Windows7 is early. In fact, I was wrong. So I chose MBR. result. . Directly divided into two drive letters. No, I don't have any points. Forgive me for not using it before and I didn’t specifically understand it. So urgent Baidu. MBR, Master Boot Record, is the existing hard disk partition mode. The MBR zoning standard determines that the MBR only supports hard disks under 2TB, and that over 2TB hard disks can only manage 2TB. To solve this big problem, Microsoft and Intel developed the GPT partition mode in the EFI program. GPT, a globally unique identifier (GUID), a GUID, and a Globally Unique Identifier. GPT is part of the EFI solution, but it does not rely on EFI motherboards. GPT partitions can also be used on BIOS motherboard PCs. Compared with the limitation of the maximum 4 partition entries of MBR, GPT has no limitation on the number of partitions, but Windows only supports 128 GPT partitions. The GPT manages hard disks up to 18EB (1EB=1024PB=1,048,576TB), but the NTFS format only supports 256TB. Since MBR partition mode can only support 2TB hard disk, 2.5T hard disk must use GPT partition mode! So how early is the system, do not support 2T + hard disk? 1. Windows 95/98/ME, Windows NT 4, Windows 2000, and Windows XP 32-bit versions do not support GPT partitions. You can only view GPT protection partitions. GPT will not be loaded or exposed to application software. 2. The Windows XP x64 version can only use GPT disks for data operations, and only Itanium-based Windows systems can boot from GPT partitions; 3. All Windows 2003 and later versions of Windows Server 2003 32bit Server Pack 1 can use GPT partitioned disks for data operations. Only Itanium-based Windows systems can boot from GPT partitions. 4. All versions of Windows Vista and Windows Server 2008 can use GPT partitioned disks for data operations; however, only EFI-based systems support booting from GPT. Specific MBRs and GPTs are of interest to learn on their own. How to do it? Think of disk management software, Diskgenius. Don't panic, let me first look at the disk information. Software Name: CrystalDiskInfo Obviously a new hard drive, the first time really gave Aunt Zhang. After verification, after selecting MBR, only 2T of space can be used. Excess space, no matter how big, there is no way to create a new partition. So, it's time to solve the format problem. Open DiskGenius, find the hard disk that needs to be changed, right-click and select Convert Partition Table Type to GUID. Because I did not change the time when the screenshot, change the success of the screenshot, so the display is gray. After the change, look at the system again. Normal. Then create a new volume. After completing the new build. It will be formatted in the background. After formatting is successful, the status of the disk is displayed. After the above process, you can finally test the speed. Test Software 1: HD Rune Pro Can only test the read operation, the write prompt does not have permission, but the normal copy is no problem, failed to test the write speed. The lowest 92.9M/S, the highest 196.1M/S. Average 157.8M/S. The CPU takes up 15.2%. Test Software II: ATTO Disk Benchmark There is a benchmark in this software name, so the test is more comprehensive. From the file size, packet size can be customized. The second test only changed one total length over the first time. Test Software 3: CrystalDiskMark The result is shown in the figure. Finally, you can actually use 2.72TB. This is so converted, 3T according to the computer algorithm is 3*1024GB=3*1024*1024MB=3*1024*1024*1024KB=3*1024*1024*1024*1024B The business changed the system to 1000, so it became 3*1000*1000*1000*1000/(1024*1024*1024*1024B)=2.72T. Since a small file is not good at testing speed, take a 1.56Gb movie to see the actual transfer speed. It can be seen that the starting speed is very slow, slowly rising to about 110, and basically stable at this speed, and software testing is almost. Reading is not very stable, starting from 200 or so, to more than 70 and gradually stable. Of course, this aspect of speed is affected by many aspects. Therefore, this test is for reference only. Noise: In the normal office environment, the sound is basically indistinguishable, but when it is slightly close to the hard disk, you hear a loud buzz. Fever: In the standby mode, the body temperature is considered normal. When the data is transmitted, the temperature will increase, but no hot conditions will occur. Unpacking and testing are over. in conclusion: Reasons for purchase: 1. Assemble the hard disk, you can freely choose the hard disk and hard disk box. 2, the appearance of personality, look good or not depends on the individual. 3, 7200 rpm, in the ordinary mechanical hard disk, you can better use the speed advantage. 4, cost-effective, relatively high. 5, after all, there are still 2 years warranty. Reasons for not buying: 1, you do not like this appearance, then I have no way. 2. Freedom to assemble, experience freedom, but there is also instability. 3, the volume, weight are not suitable for carrying, it is not a mobile hard drive, but removable hard drive. 4, the pursuit of speed or spend a higher price, buy a faster ssd. The above is the sharing content of this time, seek approval and seek rewards. Thank you for watching. Happy double!
