Deeply reveals the system quality ability of Z4X without screen TV

The Z4X completed 8000MB data read and write operations in 5.61 seconds. Its memory throughput is 1.3926GBytes/S, which is excellent. If you don't have any rational knowledge of this value, then I'll give you an analogy. The memory throughput of the open high-end Android box Q9 has been very high, and the Z4X is 1.3 times that of the opener Q9!

How to understand this value? The memory throughput is like an expressway. The wider the road, the higher the pass rate. To give an example of the most simple, we can make the Z4X do the following things at the same time without disturbing each other:

1. Hard solution to play the huge bit rate video in the built-in hard disk;

2. Two USB interfaces insert storage devices to copy data;

3. Use Thunder to download videos over the Internet to the internal hard drive.

USB3.0 speed test

Use the following command to test the USB3.0 interface speed:

(of=/dev/null does not generate writes and can be used to test pure read speeds)

Time dd if=/mnt/usb/sda2/test.bin of=/dev/null

(If=/dev/zero does not generate a read, it can be used to test the write speed)

Time dd if=/dev/zero of=/mnt/usb/sda2/test1.bin bs=1048576 count=1024

U disk using a SSD technology (SANDISK EXTREME USB3.0 Extreme Extreme 64GB), exFAT file system, the following figure is its speed (computer test):

USB3.0 interface measured reading speed: 33.12MB/S, using three reads to calculate the average method.

USB3.0 interface measured write speed: 37.61MB / S, three writes to calculate the average.

This test illustrates:

1. Z4X USB3.0 interface speed has reached the requirements of ordinary USB3.0 mobile storage devices, so although you feel comfortable buying ordinary USB3.0 mobile storage devices, Z4X will not become a bottleneck in speed, including flash drives and mechanical hard drives . Of course, the SANDISK EXTREME USB3.0 Extreme 64GB that I tested for the old demon is far beyond the scope of ordinary USB3.0 devices. It is a wolf dressed in sheepskin (an SSD with a USB coat).

2. Z4X's USB3.0 interface speed has exceeded its network speed, so you can use the Z4X with a USB3.0 storage device (or SATA hard disk) to make it a NAS.

3. The USB 3.0 interface speed of Z4X will not become a bottleneck for the playback of large-rate movies. Therefore, it is recommended to use USB3.0 storage devices to play large-rate movies.

If calculated according to the reading rate of 33MB/S, the maximum playable video bit rate of the Z4X is 264 Mbps through the USB 3.0 interface. However, please note that 220Mbps is the peak bit rate of 4K movies, that is to say, Z4X USB3.0 interface rate, fully meet the 4K original disk playback needs. Video over 220Mbps, even if you can find it, is almost always test video (for example, ducks fly).

4K video test shots: smooth, rich colors, rich details.

4K / H.265 / X.265 hard solution test

Play 4K video while monitoring the CPU usage of the Z4X. Extremely low CPU usage confirms that it is really hard to solve 4K video:

Hard solution X.265 compressed video, test video as follows:

Hard solution is normal:

CPU usage during playback:

Hard solution H.265 compressed video, Sohu encoding:

OK no problem, confirmed as a hard solution:

Local Ultra High Streaming Video Playback

Tested for high-stream video playback, "Duck-child fly" 4K video rate reached an abnormal 248Mbps, but unfortunately Z4X prompt does not support the video format.

SMB (Network Neighborhood) Limit Test

Z4X as a client, PC as a server, and a full Gigabit network environment, the commands used are:

Time dd if=/mnt/samba/192.168.1.10/Movies/1080PTestB.ts of=/dev/null

First test the performance under the WIFI environment. The router used for the test is a full Gigabit dual-band router. The Z4X is 1.5 meters away from the router and is slightly obstructed.

Connect WIFI 2.4G network:

The SMB limit rate under the WIFI 2.4G network is: 8.133MB/S = 65Mbps.

To avoid the effect of the machine cache, restart the Z4X and connect to the WIFI 5G network:

The test obtained the SMB limit rate under the WIFI 5G network: 11.08MB/S = 88.64Mbps

Judging from the extreme speed performance in the WIFI environment, the Z4X can play Blu-ray ISO-level video (about 45Mbps) smoothly through the WIFI 2.4G at a distance of 1.5 meters from the router and can be played smoothly through the WIFI 5G to 80Mbps. Rate of video (such as 4K), 1080P or even 720P re-encoded video is even more.

However, please note that in the case of full Gigabit routing + WIFI 5G, Z4X SMB speed only reached the level of 100M network. (Note: SMB speed does not represent the Z4X WIFI 5G limit speed, WIFI 5G limit speed need to use iperf test)

Next, we tested the performance of the wired network environment. The router used for the test was also a full Gigabit dual-band router. The router was connected to the Z4X using a Category 6 network cable.

The SMB limit rate under the wired network was tested as: 11.01MB/S = 88Mbps. Remove the error. This value is basically the same as the SMB limit rate in the WIFI 5G network.

Wired network limit test

(300-second Server-Side Benchmark): In the 300-second test, the stability of the wired network can be described as very good. The average speed in 300 seconds is 10.725MB/S, which is about 85.8Mbps.

(300 seconds Client-Side Benchmark): The above Benchmark is still just Z4X as a server-side running score. If it is a client, the score will be higher. Now the old demon will use the Z4X as a client, perform Benchmark for 300 seconds, and explore the extreme value of its wired network.

It can be seen that SMB has been optimized and that NFS needs official support.

Local media playback test

Local media player capability is valued by many enthusiasts. In this session, the old demon I expanded the audio-visual sample used in the 2014 Hengping review, as shown in the following figure:

Of course, some small BUG is also there, such as the audio track switching title written "3D settings", subtitle file name display is not complete, but these are all perfect.

3D video playback test

Use a meter shutter 3D glasses for testing. Found in the test, Z4X can not only play common 3D-ISO, 3D re-encoded video, and even can play 3D-4K video (4K format 3D video).

Z4X 3D test conclusion:

1. The 3D picture is normal and the picture is not flickering or dizzy.

2. 3D original, up and down 3D, left and right 3D, broadcast control is normal.

3. In various 3D modes, the built-in and external subtitles are normal.

4. The 3D picture has outstanding color, strong sense of hierarchy and high recognition.

5. Can play 3D-4K videos.

Airplay mirror test

This function is also able to transfer the images on the iPhone, iPad and Macbook to the projection in real time. This function can also be used as a gravity sensor for iPads and iPhones and gravity sensing games on the large screens of TVs. This function is also very useful in education, training, and conferences. It allows the speaker to speak through a handheld smart device (iPhone, iPad) or PC, to be presented on a large-screen projection, and because it is through the WIFI signal, Traditional Bluetooth and other methods have no restrictions on the distance of the venue, and it is extremely convenient for multiple speakers to switch. So if you think that Z4X is only used in home environment, it will be too small to see it, and it has its place in business, but it is not as good as Z4 Air.

Online video on demand

After the B-financing of the mango with the mango, Z4X also had a genuine authorization for mango. There are 3,000 movies, more than 100,000 episodes of TV dramas, a total of 300,000 hours of genuine video resources, movies, TV dramas, variety shows, anime, documentary, music, and more. And each Z4X also comes with 2 years of mango VIP service, has a member area, provides no advertising services, and even can watch live concerts.

Online music

In terms of music, Mami and Baidu teamed up and built Baidu music in the Z4X, with tens of millions of music library resources and hundreds of radio stations. However, the code rate of music is not very high. We hope to join the membership portal and enjoy high-quality lossless music.

casual games

With such a large screen, it would be a pity if we didn't play something. Z4X has a large number of small games built in that will make you entertain. Of course, if you are a serious game enthusiast, you can also connect PS, XBOX and other professional game consoles to enjoy the pleasure brought by the giant screen.

APP Mall

The Z4X app store feels good. The first is the large number of applications and the quality is good; then the classification is also relatively clear, taking care of users of different ages. Demonstrating that the pole meter is really taking care of it.

Thunder remote download test

If you want Thunder to use cool remotely, then you'd better be a Thunder paid member, so as to ensure the download speed.

Create a new download task:

Download progress:

Suggested improvements:

1. The interface does not show vip.

2. The download progress is not real-time.

3. It is recommended that the meter use ntfs commercial drivers to support NTFS writes. (Already feedback to the meter, currently being optimized)

Extreme meter assistant test

The Mi Mi Assistant is a Z4X mobile terminal control app that can be used as a substitute for a remote control or a mouse. It has full control over the Z4X. What is commendable is that its operation delay is very small and the experience is very good.

postscript

As of this writing, there is no need to say anything more. The performance of the Z4X is impressive, and it can be said that it is a product that is extremely well-made. The current price of 2699 is excellent value for money. Some of the bugs and imperfections mentioned in the article are basically concentrated on the firmware level, and it is not difficult to solve them.
