Speaking of the origin of my relationship with Qunhui, in fact, it is still quite wonderful. In 2007, with the start of the year's HTPC, I suddenly took the opportunity to take advantage of a Taiwanese mistress, using a low-cost Sempron CPU to install a Windows Vista for home sharing and backup. Soon after 2008 Microsoft made a home server version of the Windows Home Server, and I upgraded the machine to the Windows home server system. Then all the way on the hardware and software upgrades, take the technical route of their own server + Microsoft OS. After 2012, with the maturity of Microsoft's Hyper-V virtualization, a dedicated virtual machine is built into the server, which solves the overnight download problem.
However, this kind of solution has high technical requirements. For many people, there are too many things at home to work on, and they have no energy to ponder. One day in 2013, when a colleague asked me what family has a solution for sharing photos, I would recommend him to the group's DS213j often recommended by Zhang Aunt. After flickering a few times, he placed a single order when he was looking for promotions. However, the number of cheeks was increased, and my own heart was planted with grass. At the end of the year, the promotion of the 213j+2T red disk made me enter the game.
The group of things is really very worry, there are many kits, but I use the most is the cloudstation and cloudsync.
Usually work is distributed on laptops and desktops. How to keep working documents in sync is a headache. Previously tried Microsoft's groove and live mesh, but later these services are down. Dropbox is actually very good, but the free user's capacity is also about 22GB at best, and access is blocked, no way to use it happily. OneDrive's synchronization has always been a bad injury, and it often gets stuck. Domestic cloud synchronization disk? I do not trust them. In fact, what history tells us is not reliable (basically, they are all offline). Cloudstation can quickly and easily solve the problem of file synchronization on multiple hosts, and since it is mounted on its own hardware, it does not need to worry too much about privacy issues.
Another problem is backup. I realized early on that data is a very important personal digital asset. Once a lot of data is lost, it is very difficult to get it back. Putting on the NAS only solves the sharing problem, but it is not a good backup method. Viruses, ransomware, hardware failures, natural disasters, and man-made disasters can all lead to the destruction of data on the NAS. IT is well aware that effective backups must be off-site to avoid backups and raw data being lost in disasters. Cloudsync can synchronize data encryption to Baidu Cloud or onedrive as a backup.
The photostation was originally a very strong package, but unfortunately the DS213j's weak arm cpu performed poorly on photo thumbnails, and I was not used to uploading on a computer client, so it was useless.
Download station to be honest than I hope a lot worse, and the PC side of the Thunder still can not be compared, so I still use the purchase of group Hui before the use of virtual machine download.
In this way, 213j also served in my home for almost 4 years, 2 hard disk slots are inserted 2 pieces of 2T hard drives bought together that year, did not pay attention to the direct selection of the JBOD way, resulting in insufficient space is no way to upgrade large hard drives . The 213j's USB port is USB2.0, apparently no way to access the external hard disk expansion capacity. I had to hang two 5TB Seagate external hard drives on the NUC and then use the SMB shared directory to connect back to Synology. (The NUC is mainly used to run virtual machines. The file sharing management of the windows server is not as fast as the group's. Convenient), but given that the 213j has only one Gigabit Ethernet card, the actual access to the external space will not be faster than 50MB/s. (Read and then forward from the NUC, the actual use of bandwidth is only half, do not tell me full duplex, I do not know why T_T)
I've been evaluating how and when to upgrade my Synology. Zhang has performed a functional analysis and also evaluated and tested it for a long time. However, the stability of Blackgroup has not been reassuring. As the main NAS, the failure to upgrade the patch means that the vulnerability cannot be repaired in time, and the upgrade may result in lockup. Don't worry, let me store the main data.
Synology functional assessment
Although Qunhui is relying on its own software to make hardware premiums very high (for the same price, it is possible to create a set of NUCs with i5+8G memory), but people are reluctant to toss too much, and they are more sympathetic to them. The value of the solution. (This is like the iphone's configuration does not always have the same high price of the Android specification, but it is absolutely more smoothly to use them.) So determined that this upgrade to buy an x86 framework of 4 disk group Hui. Initially set as DS416play. This model is very cost-effective, is the lowest price of 4 x86 group Hui. After listening to simple technical techniques, it is also possible to run docker only with the plus series group.
After setting the target, there will be a price cut after the new product launch conference in September. Considering that Haitao has a high probability of being taxed, the price has no advantage and is still troublesome, so he seeks the help of Almighty Taobao. After looking for several businesses, I learned that the 416play that is discontinued is about 3200 or so. But 916+ can also do 3800-4000.
Hesitated for a long time, and the business owner who was doing business became a new DS918+ and won 4100. Considering that the 918+ can support 2 extra slots of NVMe's SSD as a cache acceleration, and the memory is upgraded to 4GB, it is also okay compared to the 916+.
Specific function difference profile can refer to this.
Comparison of Functions of DS916+ and DS918+
Have to admire the industrial design of Synology, how can we make new products more ugly than the old products, do not believe that everyone better than the effect.

The DS918+'s style is more oriented towards enterprise-class products, and the hot-swappable hard disk is directly exposed on the front, but the DS series is obviously a personal and studio-grade device, not the XS series enterprise-class product in the computer room... Really do not understand the logic of this design style change.
You can refer to Aunt Zhang's first article on the sun https://post.smzdm.com/p/407080/
Very simple carton packaging, accessories only manual, 2 network cable (because there are 2 network ports), the key of the hard drive lock and power cord, nothing particularly worthy of the sun, the first light up the machine to say.

Although it does not look good, it is absolutely convenient to install and use, and no screwdriver is needed. After the bracket is pulled out, the two cards with “PULL†words are pulled out, and the 3.5-inch hard disk can be installed. We see the Toga. There are four rubber washers, which can effectively reduce hard disk noise, and can also reduce the impact of hard disk vibration on each other, and thus useful for hard disk life.
The DS916+ has 2GB and 8GB 2 versions, although the 2GB of memory is not a problem for Synology Home, but considering the use of docker, DDSM, or even the loss of the virtual machine manager, memory upgrades can still be considered. DS918+ only 4GB a default version, but can be upgraded, not bad money can buy the official memory of the group Hui, specifications are DDR3L 1866. Actually I used my own Crucial DDR3L 1600's 8GB memory and it's totally fine.
DS918+ random 4GB memory
Upgrading memory is worth mentioning here. There is no need to disassemble the machine, so it will not affect the warranty. Just pull out the 2-3 hard disk trays on the right and you can expose 2 memory slots (white in the figure). That is, the default one is inserted in the memory slot inside. I'm directly replacing the default memory with a 8GB. (Now expensive memory, save some use) Although claiming to only support 8GB, but it is said that someone used 2 8GB to make the total memory hit 16GB
Memory replacement is easy
After the upgrade, the system recognizes it correctly!
Memory upgrade 8GB
The next step is complicated data migration. You can refer to the program provided by Synology's official knowledge base. However, because I plan to put the old DS213j as a backup NAS in my parents' home, I did not consider the option of inserting the hard disk directly into the new NAS. Instead, I would adopt a folder-by-folder network replication approach for migration. A long time. It is only today that the migration is done.
Retired DS213j
DS918+ officially works
The most obvious feeling of using the interface is that the interface response speed is greatly improved. This is mainly caused by the rapid increase of the CPU speed, and many functions of the x86 system are not available in the Arm system. For example, the folder compression function does not appear on the DS213j at all. , and DS918 + this feature can be used. Similarly, the BRFS file system only supports x86 series NAS.
I intend to write an article and also share some of the experiences and usages of the Quhui series over the years. I hope that I can embark on an introduction.
to sum upFinally came here to sum up the DS918+ value is not worth buying. After all, it's harder to have more than 4,000 hard drives, and counting how hard this series of drives have to be close to 6,000, for many people, this price buys a lot of computers. Yes, for the average computer users or Xiaobai, this money is definitely not worth using mobile hard disk, cloud storage, the top of the day to buy a millet routing or Thunder xx Po on it. Because they don't care whether the file upload speed is 2MB/s, 10MB/s, or 100MB/s. Data security and privacy issues have not been included in their consideration.
For people who are very fond of technology, building a windows/Linux server or even using VMware vsphere virtual servers to host the group’s work is also a way to do it. What’s more, the price advantage can’t be overestimated. watch for.
If you have a relatively large demand for data storage, and do not love tossing, then the finished Synology NAS is your food. 416play is recommended again. I think the four-bay price is definitely better than the 916+/918+ series. The 918+ series is more suitable for users with more budget. After all, the SSD acceleration disk can not occupy the slot, that is, it is not occupied. The space for hard disk expansion, after all, is definitely the world of SSD or hybrid storage (SSD acceleration mechanical disk). This design can avoid users making a dilemma between performance and capacity.
