Since the usual work uses a lot of data and needs to be saved, single data files and professional-level industrial software are often around a few gigabytes. And these data files and software are time-consuming to download from the Internet and may not always have a network. It needs long-term preservation. Buying large-capacity, high-reliability mobile hard disks is very important.
Mobile hard disk mainstream brands have Toshiba, Western Digital, Seagate, colleagues have to buy Western Digital Mobile Hard Disk, can set a password, once entered the password on the laptop after entering the folder, it was not clear what the reason is uncertain and mobile hard disk It's still related to the laptop, but it's normal the next day, so I purchased Seagate HDD. I think about 1TB for capacity, 2TB is relatively expensive, and 500GB is slightly smaller. After I placed an order from the official online store, the express delivery arrived in three days and the speed was guaranteed. After opening the box as shown below.
The back of the box shows cloud backup.
The side shows that the interface supported by this mobile hard disk is USB3.0 instead of USB3.1.
After opening the box there are instructions, mobile hard drives, data lines.
After the introduction of the manual, a large part of the language was written in different countries and the description was relatively simple.
Mobile hard disk front metal scuffed material, feel very delicate, I usually have seen other mainstream brands of mobile hard drives, a large part of more data is a plastic material, this mobile hard disk metal material is a plus, jianghu nickname also called "Golden plate"
The reverse side of the mobile hard disk is made of plastic material. It is not clear that the production of the all-metal disk is very difficult. I heard that the LACIE's mobile hard disk seems to be an all-metal shell.
Compared with a dime, the hard disk of the mobile hard disk is very thin.
The mobile hard disk interface is USB3.0 interface, the theoretical transmission rate reached 5Gbps, there are currently USB3.1 interface, transmission speed reached 10Gbps, but this mobile hard disk is not used, if used, then the price will increase. Personally think USB Type-C interface mobile hard disk should be popular, its biggest advantage is to support the positive and negative insertion of the USB interface, it is very convenient to use. Currently only a few mobile hard disks use the USB Type-C interface.
Advantages: large capacity, fast speed, mainstream brands have quality assurance.
Recommendation: If you have encryption requirements, this mobile hard disk can not meet the Western Digital mobile hard disk encryption. Toshiba's mobile hard disk feature is after the computer clicks the button to securely remove the mobile device. After some time, Toshiba's mobile hard disk will automatically turn off the light and the disk body will not rotate, but Western Digital's mobile hard disk and Seagate's mobile hard disk are on the computer. Click the button to securely delete the mobile device is still lit, the disk also has the sound of reading the disk rotation, and did not dare to determine whether each time you want to dial, just dare to shut down the computer and then pull out. In addition, it has been found that the SN code of the PN code of the Seagate mobile hard disk box and the PN code of the mobile hard disk have a different one. From the online query, it is known that the "PN code is a "production batch number", which is not unique, and the product packaging and disc The body or accessory PN code is applied separately by the manufacturer, so it is different; the SN code is the "product serial number" and can be used to query the product warranty and other specific information."
