Photo Appreciation of Qunhui DS2 18+ Products
Qunhui DS2 18+ is packed in kraft paper boxes, which is very simple. On the lower left of the front of the box, there are the logo of Qunhui and the words "Plate Station" to which the product belongs. There is a sticker on the upper right, indicating the product model and front appearance, and the black part below has product characteristics.
On the back of the package, there are mainly two stickers in the upper right corner and the lower right corner, which indicate the specific parameters of the product and other information respectively. Although it is a dual-disk design, DS2 18+ uses Intel Celeron dual-core processor, with the marked basic frequency of 2.0GHz and the highest turbo frequency of 2.5GHz.
Qunhui DS2 18+ only contains basic accessories, a power cord and external power supply, a network cable, a package of screws, a network cable and two quick start guides in Chinese and English.
The front design of DS2 18+ is very simple. The front is a cover plate, which can be opened to see the hard disk bracket and slot. There are four indicator lights in the upper right corner. There is USB 3.0 interface and on-off key at the lower right. The model number is in the lower left corner.
The four indicators are status, wired network, hard disk 1 and hard disk 2 indicator.
There are USB 3.0 interfaces and on-off keys below.
The "Synology”logo with hollow design on the right can enhance heat dissipation.
There is also the word "Synology" with hollow design on the left.
There is a fan with a diameter of 9 cm on the back, and there are some interfaces below.
The rear interface is dual USB 3.0 interface and RJ45 Gigabit network interface. There is an e-SATA interface below, and there is also an anti-theft lock hole. The power supply is 12V DC input.
Qunhui attached a network cable with the specification of CAT.5e.
The external power supply is produced by Wei Qiao, Taiwan Province Province, with a wide voltage of 100V~240V, ensuring universal use. The output specification is 12V 5A and the power is 60W.
Initial installation configuration experience
Although NAS provides convenience for our work and life, it is still a bit troublesome to install and configure a NAS before, such as installing a NAS system. Although the Synology Assistant software has been launched by Qunhui before, users only need to click "Next" and fill in the necessary login password to complete the setup. However, with the development of mobile Internet, mobile phones and tablets have gradually become the main devices for individuals, families and other users. Therefore, if you can quickly install the settings through portable devices such as mobile phones, the experience will be greatly improved.
Therefore, in the new version of Qunhui Butler App, we can easily install and set up the Qunhui system through mobile phones and other devices. Then let's experience the whole setup process.
Install the hard disk first, and then plug the power supply and network cable into the NAS to ensure that the mobile phone and NAS are in the same LAN. Press the power button on the front panel and wait for a while, then DS2 18+ will be turned on. But at this time, you can see that the status indicator of NAS is yellow. You can open the Qunhui Butler App on your mobile phone and install and set up the NAS system.
Qunhui housekeeper App is very simple, and there are not many buttons on the home page. If it is a new user, the user can click "Set New NAS". Qunhui now recommends creating a "Synology Account", which can be used for the first time to set up NAS.
Initial Interface and Synology Account Creation
During the setup process, there will be many tips to help users set up and install NAS.
Compared with the previous need to install Synology Assistant on the computer to configure NAS, the NAS system can now be installed through the App, and only the user needs to "Next" to complete it. After searching for the device, click View NAS information, and then you can install it. The actual installation speed is related to the network speed and hard disk speed, but the actual waiting time is not long, so the whole installation experience is still excellent.
Under the same LAN, you can search for NAS through mobile devices such as mobile phones.
You can see the information of NAS after searching for NAS, and you need to format the hard disk when installing.
The actual installation process and setup process are relatively smooth, but the system download depends on the network speed.
You need to set up a DSM account, which is different from the previously registered Synology account and is a NAS login account.
Fast connection settings can expand the experience of NAS, so that users can easily access the data in NAS on the external network. After setting the QuickConnect ID, you can complete the basic setup.
The quick connection setting is simpler and more convenient than expected.
The interface of IOS group manager can manage NAS conveniently.
After installation, you need to set up a "DSM account", and you can complete the setting after setting the server name, account number and password.
The advantage of this "next step" configuration method is that there are no confusing options, which really makes me feel very convenient in the process of using the experience and lowers the threshold for first use.
Drive the 2.0 beta experience
In addition to the traditional storage function, the appearance of synchronous disk makes daily work more convenient. You don't need a USB flash drive to copy back and forth. Qunhui has updated the Drive application and launched version 2.0. Although it is still a Beta version, you only need to open the beta version of "Synology Drive Server" after the beta test.
The installation process is not complicated. First, open the experience test software option in the center of the suite. Then install "Synology Drive Server" in "Test Suite" option. The installation can be completed in the next step.
Need to open the beta experience in the suite center
It can be seen that Synology Drive Server is still in the testing stage, but this version is more powerful.
Next, like most synchronous disks, you need to install the latest Synology driver software on your computer. After opening the software for the first time, click "Start Now" to enter the setting options. Select the Synchronization Task option here. After selecting "on-demand synchronization", the computer-side configuration can be completed.
Select the synchronization task here.
The QuickConnect ID and DSM account set during installation will come in handy. Enter the password here to log in to NAS.
Select the directory in the NAS where you want to synchronize files.
Select a local synchronization folder.
Make a final confirmation
Select on-demand synchronization, so that although this file/folder can be seen locally, it does not occupy space, and users can download this file/folder to this computer when needed.
After the configuration is completed, we can see the convenience. In the synchronization folder of the computer, there will be a "status" column, and we can see whether the local files are currently synchronized to the NAS. A "check mark" indicates that the file is in the local computer and NAS. And "cloud" means that there are files in this folder that only exist in NAS, but not in this computer.
In the status bar of the local synchronization folder, you can see the current file synchronization.
Click the right mouse button to select the synchronization status of this file/folder. Selecting Free Space will delete the local file, but it will still exist in the NAS. Getting links is also a very convenient function, which is similar to a network disk. You can share files/folders with your family/friends without worrying about the privacy of other files.
Right-click the file to see Synology Drive options.
You can easily get the shared link.
There is also a Synology Drive application on the mobile phone. You can also log in by entering QuickConnect ID and DSM account, which is convenient for obtaining files in NAS on the mobile phone.
Login is the same as PC.
What happens when an iOS client logs in?
This series of settings is relatively easy, and the whole is the "next step". But there is still a problem that the accounts are a little confusing. For example, the distinction between Qunhui account and NAS authorized account may still be confusing for ordinary users.
Proactive backup of business experience
Another backup function introduced by Qunhui for the convenience of users is "Business Active Backup (ABB)". Although there is already a "Synology Drive" backup, the latter is mainly for a folder, while "ABB" is mainly for a complete backup of the computer. This integrated backup scheme allows users to easily complete backup tasks without considering setting folders and other issues.
First, open the DSM panel and download "Corporate Activity Backup" in the suite center. After installation, click the "Active Backup for Business" icon in the kit tray and set it on the NAS side. After activation, it can be set. Set under the "Computer" tab to add "Computer to be backed up" to the NAS backup list. After selecting the backup location, you can set the scheduled backup time and backup file retention policy, and then click Finish to create the backup template. The newly created backup template can be used in the added device.
After installation in NAS, you need to activate the application.
Add computers that need to be backed up
However, you need to set up a backup template before adding Computers to Backup.
Select the location of the backup file in the NAS in the template.
Make a backup plan so that you don't have to back up manually every time.
Retention policy, set the frequency of deleting backups. Although it is an incremental backup, it will take up too much space in the NAS if it cannot be kept too many times.
Install Synology Active Backup for Business on the computer to be backed up, fill in the intranet IP of NAS (if the computer to be backed up is also in the same intranet), and fill in DSM account, user name and password to log in.
Summary after setting
Information being backed up
The CPU and memory occupation of NAS is not high when backing up, and it will not cause jamming when doing other operations.
After starting the backup, a notice will be displayed on the mobile phone's Qunhui housekeeper.
Synology active backup for business is an incremental backup, which can display the backup timestamp of the computer on the web page and can be recovered from a certain time node.
Synology active backup for business recovery media creator can automatically create backups on USB flash drives or create ISO file backups.
In fact, the recovery media creation tool depends on Windows ADK, but the whole installation is convenient.
When installing ADK, you only need to install the deployment tool and Windows Pre-installation Tool (Windows PE).
The whole process is fast, because all the backup files are still in the NAS.
Restoring a backup requires entering the system boot.
Fill in the IP address and DSM account of NAS and log in so that files can be recovered from NAS.
After searching the computer, you can continue the backup.
After setting it up, you can really complete the backup task without affecting your work. Open the agent software installed on the computer and you can see the backup situation. The first time it took a long time because of the need for a full backup, but since then it has been an incremental backup, so the time will not be longer.
At the same time, in the actual backup process, the CPU and memory occupation of DS2 18+ is reasonable, and there is no jam in operating NAS at this time. At the same time, it is relatively simple to create an installation image, which can be done automatically by software, and can also be created manually by skilled users. The process in the recovery process is also very simple, just fill in the account password and log in, which will basically not confuse users.
Instantaneous experience
In the new DSM system, Moments has been installed by default, and the previous DS photos are no longer visible. As the default photo management software of Qunhui NAS, Moments is also very competent.
Open Moments from DSM webpage, and you can see the uploaded photos after jumping.
In DSM version 6.2.2, Moments is installed by default.
The photo pages are arranged in chronological order.
Albums can be easily classified by a certain theme.
Intelligent assistant can help users choose photos, apply automatic color correction and classify similar photos for photo management, all of which do not need us to do it manually. It will intelligently identify photo types through AI, automatically classify photos, and save "lazy cancer patients".
On the mobile phone side, Moments can also achieve the same function. However, access to external networks still requires a QuickConnect ID. After entering the account password, the first thing to do is to choose whether to back up the photos in your mobile phone.
The options under the software are the same as the web version, including photos, photo albums and smart assistants.
Intelligent assistant, more
Cloud synchronization experience
Public cloud storage sometimes helps us a lot, but when we transfer the data in the public cloud storage space to NAS, we need many steps, which greatly affects the experience. Therefore, Qunhui has developed the cloud synchronization function. By logging in the public cloud storage to the NAS, we only need to simply enter the password and log in, and then we can synchronize the data on the public cloud to our own NAS, thus opening up the whole operation.
There are many options for cloud service providers, and Baidu Cloud and other cloud storage services are common in China.
Synchronization setting
Select a location to synchronize files on cloud storage to NAS.
To ensure security, you can set password encryption.
You can synchronize after setting.
Power consumption and transmission test
Power consumption test
Qunhui official said that the power consumption data of DS2 18+ is 5.4W- 17.23W, but it still depends on what hard disk is installed. In the process of testing, it is too much for double-disk and single-disk testing. Seagate barracuda 7200.12 (st3500418as) was used for single disk test, and Seagate barracuda 7200.12 (st3500418as) and Western Digital 1.5TB green disk. Used in DS2 18+ to support hard disk hibernation, so we can see how much sleep power consumption it has.
In the single disk test, the power consumption of DS2 18+ is about 6W when sleeping, 1 1W when standing and not operating, and 15W when writing large files, which is almost the same as the official data. In the dual-disk test, the power consumption in the sleep state is also about 6W, because both hard disks stopped at this time. Power consumption is about 17W when standing still and not operating, and about 22W when reading and writing large files. Good performance.
Transmission rate test
We are conducting two tests, namely, the transmission performance test of single SSD and the transmission performance test of SHR array composed of dual HDD. The test network is a gigabit connection, and the file size of a single large file is 4.47GB, while the test size of a large number of small files is 0.97GB, which consists of 1 0,000 files with the size of 1 MB. Test with a quick copy.
In addition, we also tested the reading and writing performance after encryption. In the double-disk test, we used Seagate barracuda 7200.12 (st3500418as) and Western Digital 1.5TB green disk (WD 15EARS) to make the test.
Because the mechanical hard disk used belongs to an earlier product, its performance may be worse, but it can be seen from the test that the performance of Qunhui DS2 18+ is very good, and the reading and writing transmission rate of a single large file can be close to100MB/s/s. In the encryption transmission test, due to the Intel Celeron J3355 adopted by DS2 18+,
Qunhui DS2 18+ NAS disassembly
As a finished product, NAS is convenient enough for users to install and configure, just put the hard disk into the hard disk bracket. Moreover, since DS2 18+ can easily expand the memory, in fact, users no longer need to disassemble the computer to expand the memory upgrade. But let's disassemble DS2 18+ to see its internal structure.
Remove the front panel to install or remove the hard disk.
The hard disk bracket is actually tool-free.
After removing the two hard disk brackets, you can see the place to expand the memory. Qunhui said that it can expand 4GB of memory, but it is 2GB, so it can have 6GB of memory capacity after expansion. However, it should be noted that DS2 18+ uses DDR3L memory.
Look at the memory expansion slot after disassembling the shell.
This is the circuit board where the hard disk interface is connected to the motherboard.
Hard disk data and power interface
The fan produced by TSMC Yuanshan Technology has a size of 9 cm and the power supply is DC 12V.
This is the back of the motherboard. You can see that DS2 18+ has two memory banks.
On the front of the motherboard, this is the PCI-E x 1 specification of the circuit board slot connecting the motherboard and the hard disk.

The memory granule is Samsung's K4B4G 16, the capacity of a single DRAM is 5 12MB, and four of them make up 2GB.
The core of Qunhui DS2 18+ is Intel Celeron J3355, but there is no laser logo on the chip. According to Intel product specifications, it is manufactured by 14nm process, with dual cores and two threads, TDP of 10W, built-in Intel Core graphics card 500, and the number of ports of SATA 6.0Gb/s is two. Moreover, it supports virtualization instruction set and AES instruction set, so Docker container can be used in DSM system, and the actual impact on transmission speed after hardware encryption is very small, and it can maintain a considerable transmission speed.
Generally speaking, the disassembly of Qunhui DS2 18+ is not complicated, but it is not necessary for ordinary users, because Qunhui has provided a convenient way to expand memory. After disassembly, it is found that the motherboard of Qunhui DS2 18+ is well designed, and the chips used are also designed by big manufacturers, so there is no need to worry about the performance problems brought by the chips.
Summary: Excellent data processing expert.
Now is an era of information explosion, not only the information that people usually accept, but also a lot of data. In the information age, the importance of personal data has long been different. In our daily work and life, we need not only synchronization, but also backup and security. The seemingly easy-to-achieve requirements add up to a more difficult task.
The appearance of NAS, a network device, initially facilitated our demand for data synchronization and backup. However, these products are somewhat "Chun Xue" to some users, and their installation and configuration are not simple, so besides hardware, software functions also need polishing. As a professional manufacturer of NAS equipment, Qunhui has long known this problem. After so many generations of updates, DSM system finally allows users to manage their own data conveniently in various ways, which is really simple, convenient and clear.
In terms of specific experience, Qunhui has indeed achieved "software and hardware integration". From the initial installation and setting up of the system through the mobile App of Qunhui Butler, the whole process only needs to be "next" constantly, and a small amount of information can be filled in. It's much easier when it comes to specific synchronous backup settings. Just like installing an App in a mobile phone, you can search and install it in the center of the suite. Even if there is a setup process, it can be easily done according to the instructions. The mobile terminal also has a good experience, whether it is picture backup or file viewing, which is no different from other network disk applications.
Therefore, both PC-side users and users who are mainly mobile devices can complete the installation and setup, and users do not need to understand various abstruse concepts and operations, and at the same time, they can ensure the demand of "high play" through some functions. At present, this Qunhui DS2 18+ will be promoted in the next 6 18 event at a price of 2650 yuan. Users who have a lot of data storage needs and want to be able to control their own data can consider this product.
