Selection and Purchase of External hard drives
Seagate Seagate Seagate 2.5-inch Backup Plus Rui-pin 2T USB 3.0 External hard drives
In line with the purchasing purpose of buying only right but not expensive. Often buy a product and do some research on it. Only when you have a thorough understanding of the product, you dare to join the shopping cart. With the full reduction of vouchers, white-strip vouchers, and price forecasts, it is often necessary to achieve the lowest price in history before daring to cut hands.
Think about it. Is it so much trouble to buy something? Especially in the east of Beijing, various kinds of securities emerge in endlessly, and the Double Eleventh Event is flying all over the sky. It is too difficult to achieve a real historical minimum price. Many-valued friends lament that shopping is a real test of the mathematical level and analytical ability.
Is it worth buying like this? Different people have different opinions on this issue, but wise people have different views. But every time I buy something, I know it better, compare it with three, and get the best value. Finally, I get the product delighted. Know more and be more affordable. If time and energy permit, why not?
The product that will be introduced this time is an external hard drive. With the closure of cloud disks one after another, especially recently the second largest cloud disks in China, "360 cloud disks" officially announced the closing to the outside world, allowing mobile hard drives to re-enter the consumer's horizon, and prices have risen one after another.
This paper will be composed of two parts: free hard disk selection and Seagate sheeting, and hard disk testing.
1: Selection and Purchase of External hard drives.
The most important thing for me to buy an external hard drive is the transmission speed. After all, it's maddening to lose the speed when transferring several gigabytes of data. At present, the mainstream external hard drives in the market are all USB2.0 and USB3.0 interfaces; the main difference is the transmission speed. And the transmission speed of USB 3.0 can reach 60MB-140 MB/s, which meets my daily needs. Selecting a high quality mobile hard disk is very important because external hard drive data recovery is very troublesome.
About the identification of USB 3.0 interface, generic products will specify, after all, USB 3.0 is a selling point of the external hard drive, if there is no particular description, it should be USB 2.0. There are two ways to distinguish USB2.0 from USB3.0 by the naked eye. Look at the interface. If it's blue, it's USB 3.0.
Before purchasing an external hard drive, we need to assess our needs. The price of a portable hard drive will double with the increase of capacity. Especially the situation that the network disks have been shut down one after another makes the price of an external hard drive increase significantly in the past year. It is recommended to buy a portable hard disk with a capacity of more than 1TB. If the demand for data is unusually large, you can choose 4TB.
Because the conversion method is different, if according to the normal binary algorithm, 1KB = 1024 byte, 1MB = 1024 KB, 1GB = 1024 MB, 1TB = 1024 GB, but some hard disk manufacturers in terms of computing capacity are carried per 1000. Namely: 1KB = 1000Byte, 1MB = 1000KB, 1GB = 1000MB, 1TB = 1000GB, this difference caused the "shrinkage" of hard disk capacity.
If you encounter the hard disk "shrinkage" lost, these are normal phenomena, and you can be assured when you buy this situation. If the capacity gap is too large, it should be righteous and vigorous to defend the rights of businesses.
As a portable hard disk, size and weight are important factors we need to consider. There are three common types on the market: 3.5 inches, 2.5 inches, and 1.8 inches. Considering the requirements of anti-seismic, heat dissipation and other functions, 2.5-inch hard disk should be our first choice.
In summary, I finally purchased Seagate 2.5 inch Backup Plus Rui Pin 2T USB 3.0 external hard drive.
2: Seagate External hard drive Show:
Amazon bought 559 yuan. However, many valuers have reported that they can buy this price a year ago, and there are still cheaper times. But who made the network disk sluggish this year, the amount of the external hard drive is also in line with market rules. Pearl white is often made special; if you want to start this portable hard drive recently, you can pay more attention to pearl white.
The package is marked with OneDrive for 200 GB. OneDrive is still good to use. After all, it's Microsoft's parent and son. It's set to boot. But sometimes it needs to turn over the wall, and the transmission is not stable, so I also save a little document, 200 GB of storage space is not used, there is no operation.
Seagate is still good at software. Windows and Mac are equipped with mobile hard drives, and Google Play and AppStore also have apps to download. The USB 3.0 interface is also downward compatible with the USB 2.0 interface.
External hard drive distribution line is a USB 3.0 data line, which is too short to use. As mentioned earlier, the Blue interface proves its UBS 3.0 attribute.
When we unpacked the package, we saw the main character of our sheet, the Pearl White Seagate 2.5 inch Backup Plus removable hard disk. White is more natural to dirty, and the plastic feel is obvious. One of the selling points of this external hard drive is "high-end metal". So when I first got this product, I had a tangle about whether it was a metal plate or not. Perhaps it is because of these shortcomings of Pearl White that we often make special offers.
But the most satisfying thing about this external hard drive is its size and weight. The 2.5-inch mobile hard drive is too portable. My previous external hard drive was a retrofit of an old laptop hard disk. Although it was equipped with ORICO 2.5-inch hard disk box, it was still more significant than the standard external hard drive.
This external hard drive has three sizes: 113.74 mm long, 77.02 mm wide, 12.80 mm high, 125 g weight, and 148 g data line, which is smaller than 159 g official data, so Seagate official data is still very modest.
3: Testing External hard drive：
Here are some summaries of Seagate's 2.5-inch Backup Plus 2 T USB 3.0 external hard drive based on its usage:
1. Small size, light weight, suitable for carrying.
2. Complete supporting software and convenient backup.
3. The transmission speed of USB3.0 satisfies the daily use. It's much faster than cloud storage.
1. The data line is too short.
2. Pearl white is easily dirty.
3. White has some "plastic feeling" and does not reflect the "high-end metal" texture.
With cloud storage closing down one after another, buying an external hard drive is still worth it. Although I read a lot of friends comments, for Seagate external hard drive stability has a lot of Tucao. But Western Data and Toshiba's External hard drive Review Zone have also had some problems. So based on the use of this period, I recommend the Seagate Backup Plus series.
