But don't worry too much. NAS devices, which used to be used only by enthusiasts, have now entered the homes of ordinary people. On the basis of effectively meeting everyone's data storage needs, it also provides some commonly used "just-needed" functions, which are enough to meet the daily needs of ordinary users. Although Lvlian is an old-fashioned powerhouse in the field of digital accessories, it can only be regarded as a new force in the field of NAS. Then, what is the performance of his new NAS product "Lvlian Private Cloud DH2 100" (hereinafter referred to as "Lvlian DH2 100")? Is it worth starting with?
The packaging of Lvlian DH2 100 can be described as simple and intuitive, with product renderings, automatic backup, extremely fast transmission and remote access highlighted on the front. For ordinary users, automatic backup is what I want, and remote access is what I want, which is also the basic function we need every day.
The function and parameters of the product are introduced in detail on the back of the package. Specific parameter information is as follows:
Main chip: Realtek RTD 1296 64bit, Cortex-A53 quad-core, 1.4GHz.
Memory: 2GB DDR4
Storage: 8G eMMC
Disk location: dual disk location
Interfaces: USB-C* 1, USB3.0* 1, USB2.0* 1, Gigabit network port RJ45, power interface.
Although the positioning is home NAS, the hardware configuration of Lvlian DH2 100 is quite reliable. Realtek RTD 1296 adopts standard 64-bit ARM cortex-A53 core CPU and is equipped with 16nm T820 three-core GPU, which has a good performance in decoding audio and video files, and high-quality 4K Blu-ray video is not a problem. Therefore, in addition to the basic data backup and remote access functions, this Lvlian DH2 100 will be a good audio-visual player. If the TV configuration at home is not good, you can rebuild the audio-visual entertainment system around after the setting is completed.
As for accessories, in addition to the mainframe, there are small power adapters and flat network cables that are not easy to wind. In addition, there is a set of tools for installing 2.5-inch hard drives, including screwdrivers and screws. However, for most people, using a 3.5-inch mechanical hard disk is the most cost-effective way to meet the demand.
As a dual-disk NAS product, Lvlian DH2 100 has a small volume, a rounded overall shape and a good texture performance under metal dust. If put on the desktop for daily use, it can be effectively integrated into the home environment without being abrupt.
There are two lines printed on the sticker on the top cover: "I am guarding your story in the sun, moon, stars, mountains, lakes and seas", which adds some cultural flavor to digital products, but I think it may be better to design these two lines on the fuselage in other ways. After all, once the sticker is removed, the cultural flavor will go with it, as if it had never appeared. ...
The front of the fuselage highlights the IO area through the design of regional division.
There are four status indicators: power supply, network, hard disk *2, * 4. Below are Type-C interface and USB 3.0 interface, which can connect storage devices with different interfaces. It is also very convenient to plug in and dial common high-speed interfaces on the front of the fuselage.
Above the back is the radiator, and the black IO area below includes the reset button, USB 2.0 interface, RJ45 gigabit network port and interface.
Lvlian DH2 100 adopts dual-disk design, but different from traditional NAS products, its hard disk installation position is set at the top, and the top cover can be popped up by lightly pressing the logo. You can see two vertical hard disk brackets with the font "UGREEN Design" on them.
When you take out the hard disk bracket, you can see the fan at the bottom of the fuselage, which is relatively large in size, fully ensuring the heat dissipation effect during operation.
As for the installation of the hard disk, it is very convenient to use a 3.5-inch mechanical hard disk without tools at all. As for the hard disk, I use two Seagate Cool Fish hard disks in my own hands. The disk version of Green Link DH2 100 is equipped with professional NAS disk Seagate Cool Wolf. You can choose an empty disk version or a disk version according to your actual situation.
After fixing the hard disk, insert the hard disk bracket into the installation position of the hard disk without tools.
Plug in the power cord and network cable, and all the preparations will be completed. There is basically nothing to see in the whole process, and the computer can handle it.
Lvlian Cloud supports three platforms: Windows, Mac OS and Android. You can download the software of common platforms according to your actual needs. It is said that there will be a TV version later, so you can pay attention to it.
Take the Android client as an example. After the new machine is connected, it only takes three steps to bind the device: 1, and register and log in to Lvlianyun; 2. Scan the devices in the network; 3. Complete the device binding. The whole process is completed at the prompt of the APP, which is not difficult at all.
After the device binding is completed, the next key function selection is to select dual-disk storage mode, which is divided into RAID 1 backup mode and normal mode. The simple understanding of RAID 1 backup mode is that one hard disk is used for storage and the other hard disk is used for mirroring, and the data of the two hard disks are consistent. The damage of a hard disk will not cause data loss, which is of high security, but it is actually only equivalent to the data capacity of a hard disk. In normal mode, the two hard disks are independent of each other, and the storage capacity is the sum of the two hard disks. If there is something wrong with any hard disk, the data will be affected.
In my opinion, since there is a need to choose NAS devices, we must pay more attention to data security. It is recommended that you choose RAID 1 mode to ensure data security after using hard disks with sufficient capacity in one step.
After completing the relevant settings, you can enter the control interface. Because Lvlian Cloud DH2 100 is positioned as a home NAS, its functions are all the common functions we just need in daily life, including automatic backup, Samba, thunder download, Baidu network disk and so on. The function is not complicated, so the software interface of each platform is relatively simple and intuitive.
It can be said that the whole configuration process of Lvlian Cloud DH2 100 is quite easy, and it is no exaggeration to say that it is easy to get started.
In addition to device binding and storage mode selection, Samba functions need to be set simply, mainly by setting user name and login password, and then following the system prompts, so that Samba functions can be easily realized.
1, equipment information
After the configuration is completed, you can view the related device information and hard disk status in the setup function. If RAID 1 backup mode is selected, if no new data is stored in the device for a long time, the "mirror" hard disk is in a dormant state, and after the main hard disk has new contents written, the "mirror" hard disk will automatically resume its running state to ensure the data consistency of the two hard disks.
2. Samba and speed performance
Log in and visit the IP address of Lvlianyun DH2 100 displayed in the system, and after verifying the user name and password, you can easily access the data in the NAS device just like using a computer, which greatly reduces the use threshold and allows users who only know the basic operation of a computer to easily back up and retrieve the data on the PC side.
According to the actual test, the writing speed of Lvlian DH2 100 is basically stable above1100MB/s, and the reading speed fluctuates slightly, which basically reaches the peak of gigabit network transmission speed, whether you are backing up data in a local area network or directly accessing devices.
According to the actual measurement, the wireless download under the local area network can reach 60 MB/s. Although the transmission speed of wireless signal is not as fast as that of wired network, it is completely no problem to directly access the HD video resources in Lvlian DH2 100 in the local area network, so you can watch it smoothly without worrying about buffer loading.
In addition, when WiFi is not connected, Green Link DH2 100 requires users to manually turn on the switch of mobile phone traffic download before downloading or backing up related tasks, thus effectively avoiding traffic loss caused by mistakes. According to the actual test, the speed of downloading movies through mobile network in Lvlian DH2 100 is about 2MB/s, which is not very fast, but it is ok. When you need information urgently, you don't have to wait long. PS: Data network speed is greatly influenced by signal quality and terminal conditions, so the speed varies from person to person.
3. Automatic backup
Automatic backup function is one of the functions that ordinary users also need very much. The data of mobile phone and PC can be backed up separately through Green Link DH2 100. Taking the mobile phone as an example, we can not only actively select the directory of mobile phone files that need to be backed up, but also make a special backup of WeChat files, which can fully consider the mainstream needs of current users and make the function easier to use.
4, photo album function
Another outstanding change brought about by the popularity of smart phones is that taking photos has become one of the most commonly used functions of our mobile phones, and everyone has become a photographer. In this case, how to deal with huge photos?
Similarly, Lvlian DH2 100 has specially set up the photo album function, and we can create two kinds of photo albums, one is a personal photo album visible only to ourselves, and the other is a * * * photo album visible to everyone. After a day's play, you can set up an album in time and sort out the photos in different categories, which is not only simple, but also convenient for later search and browsing.
5. Thunder download and Baidu network disk
Personally, the two most commonly used download tools are Thunder and Baidu. I believe this is also the choice of most users.
Lvlian DH2 100, which integrates the function of Thunder, is as simple and easy to use when using Thunder on PC client as using Thunder software alone. The download speed of reliable resources can easily reach above 10MB/s, and 4k HD resources can also be downloaded quickly.
Relatively speaking, the download speed of Baidu's network disk is still seriously affected by whether it is a member. If you are not a member, the download speed is not fast. NAS devices which mainly focus on data backup also have the characteristics of low power consumption. Let it flow 7*24 hours without membership!
6, video playback
Using Lvlian DH2 100, we can access the high-definition video resources in the device online through the APP, and we can choose the built-in player of Lvlian Cloud or the mobile phone player. The performance of the built-in player of Lvlianyun is still excellent, so it is recommended to choose it.
Not only can you watch movies smoothly anywhere in your home through the LAN, but you can also easily project videos onto the big screen TV through the recently updated DLNA function of Lvlianyun, so that the whole family can enjoy watching movies on the big screen.
This green couplet DH2 100 has been used for a month. In a word, its most prominent advantage is its simplicity and ease of use, while its disadvantage is its simplicity and ease of use.
How can I put it? Lvlian DH2 100 has a clear positioning, that is, home NAS, so the feeling after using it during this period of time is that it is simple to install, set up, use and function, which can effectively meet the daily data storage and backup, data download and audio-visual entertainment needs of ordinary families. And the price of this NAS device is also very entry-level and approachable. The price of a diskless single host is only in the early 1000, which is very suitable for family early adopters who have never been exposed to NAS.
It is precisely because of its simplicity that users can only use the functions provided by the product, but can't expand and extend it, so the playability of this NAS device is very general and it is not attractive to advanced users.
Therefore, my suggestion is that if there is a need for data backup at home, but you don't know much about NAS equipment and don't want to go deep into it, then Lvlian DH2 100 is a very suitable choice, which is simple and easy to use, with few functions but very practical, and basically covers the daily main needs. And the price is cheap, and the overall cost performance is good. You have to toss it in the future, and you won't lose money if you change it again. Not bad, huh?
