It is estimated that someone should ask how to buy a mobile hard disk again, and it is still such a small 1T. If I said that the last time was not enough, would you believe it? ? Well, actually, do you need reason? do you need?
This time, it was superimposed a discounted punch of 16 yuan from the Aunt’s office and won at 403 yuan. The price did not have the last "New Element Series" offer. However, in the actual test, it is really a penny and money.
Western Digital (WD) New My Passport 1TB 2.5-inch China Red Mobile Hard Disk WDBYNN0010BRD-CESN429 yuan Jingdong direct link After you have a nonsense, please feel free to take a look at your personal (bian) line.

ã€One, out of the box】
Western Digital 1TB high-end colorful (red) mobile hard disk (hereinafter referred to as Western Digital 1T China Red) box compared to the new element series to buy before to get some grade. Yellow and white color background highlights the appearance of the middle red hard disk. I just for this appearance only the entire goods Oh.
There is a sticker on the box which is very eye-catching. For hard drives, CPUs and other products, the reputation of Lianqiang agents has been good. The strong warranty personally feels quite awesome. I remember that the previous hard drive had two months of overdue insurance. There was no invoice, and Lian Qiang renamed me directly on the serial number.
The back and bottom of the box are marked with the "three-year limited warranty" and "Thailand" manufacturing. I remember that in the year of the flood in Thailand, the three big items rose to the sky-high price, and they didn't fall back for a long time. It was a DIY nightmare.
Western Digital 1T China Red uses left and right pull-out shell designs. There are no fragile marks on both sides, so just open the hair dryer.
The box is of good quality and is much better than the texture of the "new element series". But there is still a sandwich cookie recipe inside.
Although it is a sandwich cookie, this “Western Digital 1T China Red†is more structured than the “New Element Seriesâ€. At least USB data cable and instructions are not on both sides, have their own storage slot.
Family portrait oldest: manual, USB data, mobile hard disk. There is nothing to say.
=========================== Split Line ===================== ======
"Western Digital 1T China Red" has a two-stage design with the same plastic material. The hard disk is accurately divided into two parts by a recessed slot in the middle. The upper part is smooth and the lower part is a slightly matte twill slip design. The four corners are rounded and the frame is not cut. It feels good to get started, and it's easy to scratch.
This time the hard disk interface is at the bottom. The white status indicator next to it did not do a hidden design, which was a little abrupt. The official introduction is that "support smart backup", but there is no backup key and lock key, all based on the supporting software features.
The "Western Digital 1T China Red" design style on the back is the same as the positive one. That is, the parameter label just above it is quite eye-catching. Personally feel that it is too abrupt, affecting the overall appearance. Is it actually possible to consider the design on the side?
The four corners on the back of the hard disk each have a square non-slip point. This is very different from the "new element series." The circular type was changed to a square type, and the contact area was larger. Theoretically, it should be more slippery.
"Western Digital 1T China Red" adopts USB 3.0 interface, of course, the data line interface is also blue. The other end of the line is a USB3.0+USB2.0 compatible interface. This line is softer than the "New Element Series" and not so hard.

In order to compare with the previous "new element series" hard disk, this time it was tested with the same office computer.
Miscellaneous things are defamatory and non-paper seven: a stable product of moderation, WD Western Digital's new element series 1TB mobile hard disk out of the box just need a mobile hard disk. Not for the big sister, my heart is not for my big sister. This is my job. I need to copy the work files from the company computer back home. In the meantime, I would like to move some of the games downloaded from the company’s website to the home... I don’t have any clue about the choice of mobile hard drives.

Because the "Western Digital 1T China Red" purchased this time comes with its own encryption and smart backup functions, the software is different from the "new element series," but the software is not included in this test.
This time, the USB2.0 and 3.0 interfaces were tested using HD Tune Pro, atto disk benchmarks, Fast Copy, and Crystal diskmark.

â– HD Tune Pro Test
First, confirm the hard disk with HD Tune. 1T hard disk capacity, 5400 RPM.
All settings are the same as before. Adjust the quick stroke to 10GB. Then plug in the host's USB2.0 and 3.0 interface tests.

The difference between the minimum and maximum speeds is a bit large, and two of them appear in the line graph. Huge fluctuation peak.
(New element series: 27.7MB/s, 30.1MB/s, 29MB/s)
â—† Under USB 3.0 mode, the minimum transmission rate is 98.4MB/s, the maximum transmission rate is 118.4MB/s, the average transmission rate is 113.2MB/s, and the difference between the minimum and maximum speeds is 20MB.
(New element series: 91.7MB/s, 110MB/s, 106.1MB/s)

â—† In USB 3.0 mode, the minimum write speed is 162.6MB/s, and the maximum read speed is 176.6MB/s. Read and write speeds are quite close.
(The new element series is: 109.7MB/s and 109.3MB/s.)

â– FastCopy test
The previous file was deleted, so the test selected a video file of about 2GB.
Fast Copy test results:
â—† [In USB2.0 compatibility mode] Video access speed takes 46.9 seconds and transmission speed is 40.5MB/s.
â—† In USB 3.0 mode, the video access speed is 17.2 seconds and the transmission speed is 110.2MB/s.

Crystal diskmark test results:
â—† In USB2.0 compatibility mode, the maximum is 45.41MB/S continuously, and the write speed is 45.12MB/S.

=========================== Split Line ===================== ======
ã€to sum up】The "Western Digital 1T China Red" exceeded the "New Element Series" in all tests. Atto and Crystal diskmark test results are the biggest difference between the two. Among them, USB2.0 mode has reached a gap of 12MB/s, and USB3.0 mode also has a gap of 7MB/s. One second at 12MB and one minute at 720MB. It's very obvious to think about this difference.
â— Advantages: 1. Strong warranty for three years, after sale to force. 2. It is fast and relatively stable. 3. The sound is small. 4. Support software encryption and backup.
â—† Disadvantages: 1. Smooth plastic easy to get flowers.
I remember that the "new element" is 361 yuan to start, it really is a penny and a cargo wow. There is also official encryption, which can come in handy at least when handling important documents. Big sister is not to be discovered. If you say something wrong, it is an important document of the company that should not be leaked, such as payroll, contract, planning agreement...
Finally thank you for seeing the end of the value of friends, a picture of the sister on it. Don't ask who my two sisters are.
