  • Solid product. Couldn't be happier.
I had tried a few different storage solutions for my Home and family's small business, but no solution I tried seemed to work the way that it was advertised or meet my needs. In all honesty it was because of my choice to try to find a budget solution because $400 for a NAS and then another 4-500, at least, for drives to put in it is a lot of money. I can't begin to describe how happy I am I did it though. This is a solid product. I can't speak to the uses for a media server, because I haven't gotten around to testing those features yet, but for a storage solution I can. This NAS makes back ups, data storage, and file sharing extremely easy and not just because I'm a computer science major. Even for people who may not be the best with computers, set up is super easy and the web interface is simple and very intuitive. Set up on a local network is extremely easy. Set up for remote access for multiple users though, while still much simpler than something like an Ubuntu server, still will probably require a little more than average technical and networking knowledge. Especially if running an antivirus and/or firewall as you will have to make exceptions for the remote IP address. For creating a remote network drive, you will also need either a static IP address or a domain name and a DDNS service. Overall though so far, I couldn't be happier with the product and am glad I decided to spend some extra money and get something that works great, is easy to manage, and meets all my needs. I will try to come back and update once I have the opportunity to text some of the media server features. UPDATE: So I have now had the opportunity to test some of the features using this as a media server. I have put some movies on it and and was able to stream them. My conclusion is I have some good news and some bad news. Lets get the bad news out of the way first. Bad News: If you are a fan of Plex you may be out of luck. Synology seems to have discontinued support for Plex for all model NAS servers aside from those using an intel processor. According to the Plex forums, some of the older DS418 models do have the intel chips but almost all of the new ones have the Realtek quad cores in them. Fear not though, I did find an alternate solution I will share in the good news. One other thing I did find is if there are some other services running while you are trying to stream HD video you may get some stuttering occasionally while there is other uploading or downloading going on in the background. I'm not sure if this is related to the processor or the limited amount of RAM but I plan to add more RAM in the near future I have also recently enabled the ethernet port aggregation and will test to see if that makes any difference as well. **Note: True Port aggregation will only work if you have a router that supports it. They do have a Load balance bonding but it is not the same as port aggregation. Will retest after these modifications and report back again with another update. Good News: The good news I found is, though there is some stuttering it is pretty easy to work around it by pausing some of the back up services you may have running while tyring to streaming video, which, while its not ideal, I don't find to be that big of a deal given the price point compared to other solutions. The port aggregation I enabled recently along with my plan to increase the RAM may even resolve this issue. The other good news is, for those of you who don't have your heart set on Plex, there is an application for the Amazon FireStick called Archos that seems to work very well in my opinion. You can browse all your folders on the server look at pictures, play music, and stream video. So far I have only tested this while streaming on my local network and have not yet tested remote streaming using this application. Once I have had the opportunity I will again report back with another update. ... show more

  • Very Happy
I've been using the Western Digital MyCloud products for TimeMachine backups on our Macs - The WD products were never particularly stable as a network backup target. When one of the WD's died, I decided to invest in the (admittedly more expensive) Synology DS418, and I'm very happy that I did. Set up was easy, and TimeMachine backups from multiple Macs are working very smoothly (Tips: SHR volume. One shared TM folder. One "user" per Mac with a quota. Do the first backups one at a time!). The only thing to be aware of is that adding/replacing a disk is not fast - adding a third 4TB disk to my config, took the DS418 a couple of days to merge it in, but it did so without difficulty. Overall I'm *very* pleased at how little I have to fiddle around with this server. It just works. UPDATE May 2020: I've had the DS-418 under continuous use for about 2 years now, and I thought I'd add a few additional comments. (1) I initially chose the DS-418 as a device to back-up our family laptops. As mentioned in the original review, it was easy to set-up and works seemlessly with Mac OSX's TimeMachine for all the laptops. Two years of back-ups to the DS-418 have been flawless - the laptops' TimeMachines quietly and automatically back-up each laptop any time they are on our wireless network without the user even noticing. Perfect. (2) I had a drive failure (an older repurposed drive - not unexpected) in a 4 drive configuration and I was thoroughly impressed by how easily the DS-418 recovered. An audible alarm and light alerted me to the failed drive but the DS-418 continued to operate in "degraded mode" allowing me time to order a new drive. Once the new drive arrived, I pulled the old drive, inserted the new one, and started the rebuild. The rebuild ran entirely in the background over the couple days. Net result: ZERO downtime. Easy/complete rebuild. ZERO data loss. I'm EXTREMELY happy with the recovery and data integrity capability of the device! (3) Synology has been excellent about software patches and communication of potential security issues. A couple mouse clicks in the web interface after an email notification is all it takes to manually update it. Alternatively, you can schedule a time one or more days per week to check and automatically apply updates. Again, EXTREMELY happy with this feature! (4) As of this writing, there are 104 (Synology and 3rd party) packages that can be added to the DS-418 to customize the services and capabilities, like audio/video servers, home security camera integration, photo organizers, webserver software, and more. The packages install with a single click. Very easy. I'm running several add-on packages and the DS-418 is still running very smoothly. (5) The resource monitoring tools and storage analysis tools are very good. Easy enough to be helpful for first time users with sufficient data and detail to satisfy more advanced users. ... show more

  • Buy this now, it just works!!
As a photographer I have run through my laptop storage (250GB) and my additional external 500GB storage, so after a number of YouTube videos I settled on the Synology DS418 as a solution for this problem. Looking for in purchase: -Sturdy -Value -Hot Swap -Link Aggregation -Easy Setup -Four Bays Minimum Design: The design of this product is sleek and well designed, while it is a plastic it seems to be a sturdy and hard plastic that will last for a significant amount of time. There is a USB port in the back along with 2x 1GB LAN ports (link Aggregation compatible) and a USB port up front. There are four bays that all have access from the front and the bays are lockable. Size is not a significant issue and it fits easily on a cart shelf. Issues: The setup on the computer is not as easy as I thought it was going to be, but as long as you take time to read instructions online there is no significant problems. I believe that the time to get everything online is somewhere between 1-3 hours depending on how computer savvy you are (it took me 3-4 hours, to set up four different storage areas on the NAS (2x Time Machine Backups, a folder for my photography and a folder for general family storage, then to provide access to mine and my wife’s computers to where everything worked seamlessly). All of that said none of it is a real issue, because Synology directions are fantastic. Cost: $369.99 (and worth every penny) Positives: ++Cost ++Link Aggregation ++Hot-Swap Capability ++Design ++Build Quality ++Noise Negatives: --None Final Thoughts: I LOVE THIS. It is so nice to free up hard drive space on the computer and to get rid of all the dongles needed for all the external stuff. The system works flawlessly and after it is setup and about a day of playing with it everything seems really intuitive. I set this up with 2x WD 2TB RED drives and the system was up after plugging it in, following the basic instructions and some auto updating (total of about 20 mins). I have one volume with four folders (2 Time Machine Backups, a folder for photos, and a general storage folder) that are have dedicated space and users assigned to them. The backups work with no issues and our MacBooks link right to the system, even if we go away for travel and come back. I can’t believe I have been asleep at the wheel when it comes to NAS and I will never use cloud storage again. Especially when I can access my NAS anywhere in the world via the internet with just a couple of clicks. Would I recommend: Yes, 5 Stars and easily would recommend the system to anyone who needs a system. ... show more

  • Nice unit but not perfect
This is a great little NAS but with some definite downsides. Synology's operating system is the high point and what really sells it, it's very nice and well laid out with every feature you could think of and makes it relatively painless and simple to setup. There are packages you can download through their integrated package center for the features you're looking for which includes the ability to host your own websites, VPNs, media servers through DLNA, etc. It has vast configuration capability and makes setting up basically any RAID array you want a breeze. It comes with 2 GB ram and a quad core processor that seems to be more than enough for your average NAS unless you plan on utilizing it as a high traffic web server. The two built in fans are much quieter than I thought they would be (basically inaudible) but I also have them in quiet mode, there's a cool and full speed mode as well but the drives don't run hot in quiet mode so I just left it there. The NAS claims that the fans will adjust in speed as the drive temperatures rise automatically in all three modes so... The cons: It's cheaply made, basically entirely plastic except the internal drive bay cage. Even the individual drive cages are all plastic and the locks feel like you could break them open without much effort. It only comes with two 1 Gbe ports which is fine I suppose for an average home network server but it basically maxes out at around 112 MBps transfer speeds unless you use link aggregation (more about that below). Needless to say when you have terabytes of data to transfer it takes a very long time at 112 MBps or less. As to that link aggregation, it's certainly a nice option to have but there are big caveats. In order for link aggregation to work your router and/or switch also have to support the feature and be configured on the other end, including at each end of your computers unless you also have multi-gig ports on your computer AND router/switch, so you can't just simply get a 2.5 gbe unmanaged switch thinking you'll get the full 2 gbps bridged speed. The DS418 does have two USB 3.0 ports on the front and back and there are USB3.0 to 2.5 gbe adapters available however I have yet to try to see if they will work on the DS418. All in all, this is one of the better small scale NAS devices available considering pretty much everything else that is comparable or has more features are significantly more expensive. I still think it's a bit overpriced for what it is though considering there are options to build your own NAS that would be significantly more powerful for not a lot more (I speced a system that would have only been about $140 more but with a 12100, 4 times the ram and better quality hardware for example) but I was looking to keep my costs down. ... show more

  • Fantastic device for simple, easy backup solution
For what it is, this is perfect. I have a fairly complex home network compared to the average user. I have 2 enterprise class servers, one as a router and another as a Proxmox hypervisor providing VM's and filesharing to my network. I've previously used a 4 bay USB 3.0 enclosure and a Raspberry Pi for backing up the Proxmox server's fileshare in another room in the house, and while cheap I regularly ran into problems with it. I decided to bite the bullet and get something real. Setting up the Synology was dead simple. I honestly thing my technology challenged parents could do it with little to no supervision. By default it setup my 4x14TB drives in it's SHR1 RAID setup, but I wanted RAID10 so I wiped it out and build the RAID again. Again, pretty simple, but this would have been a bit more challenging for my parents. I did poke around and their documentation does a good job explaining why you might want a certain type of RAID over another and how to do it, but personally I think it'd be good to offer the option during setup instead of just doing SHR1 from the get go. Setting up the backup for my needs was more challenging but not ridiculous. Definitely beyond most folks, but for those inclined getting the SynCommunity package resource added, a couple packages installed I'd need (mostly for nano, rsync, and a couple other shell tools), and getting SSH enabled was easy. I mounted my NFS shares from the File Station app on the Synology and made a quick little backup.sh single line script to backup my share to the Synology RAID, made a Task Schedule to run it nightly, let it run for ... a few days (~19TB of data to move took a while), and it was done. Why the copy was happening I plugged the 4 bay enclosure I have into the Synology so I could setup a couple other things for fun, and it's now just running smoothly. Set up SNMP real quick so my Zabbix VM could let me know if there's trouble but otherwise it's now just sitting in a closet providing peace of mind. The benefit I saw from setting this up is that it's the first time I've used DSM and I had it up and running, in a fairly advanced way, really quick. It took ~30 minutes from taking it out of the box to starting my copying. While a unit like this won't fit everyone's need, and in some cases be overkill, it does it's job really well and I'm happy to recommend it to others. ... show more

  • Nice upgrade from my old DS213
The 4 bays give a lot more flexibility in using different drive types, compared to the 2-bay version I had before. I'm also getting nearly gigabit data transfer, and that's with just one of the two available network ports. I'm using the NAS as a backup location, not for primary data storage. It has backups for a desktop and two laptops, and I plan to keep several full copies of each, in case of a desire to roll something back. In this scenario I'm using the bulk data storage capability fairly heavily, but I haven't tested it as a media device or with any of the many applications you can run on it. It's a good thing that everything works well, because I have a feeling that support is a little grumpy. I had the common experience of finding that changing the number of drives is very slow (days). There's probably good reason for that, but I just wanted to understand what was going on and how long it might take. The forum threads I found were generally closed, and ended with the message that users should not waste the developers' time with such hard questions. Back to the positive, the initial setup is fast. It's only slow if you change your mind or otherwise need to add drives while preserving all the data. When I swap out my smallest drive for a bigger one in a year or so, I'll be prepared for a wait. It will also be less important since the NAS still works during the task, and now I have gotten past the initial "lets try and test everything right away" state. By the way, I'm using WD Red drives in 10, 6, 2, and 2 TB sizes. You would never choose that mix, but I had the three smaller drives already, and plan to upgrade to all 10 TB drives as my needs and budget evolve. The nice thing with Synology's SHR version of RAID is that I get 10 TB of single-fault-tolerant storage out of that mix, where RAID 5 would give only 6 TB because of the mismatched sizes. ... show more

  • So easy to setup, it feels like I'm cheating.
This is the first off-the-shelf NAS product I've purchased. In the past, I've set up my own server using a repurposed old desktop system with multiple disks in a raid array. It's almost been a hobby. I needed a very fast solution that I didn't have to worry about setting up. This was easier than I ever could have expected I really like this product; it's got a very easy interface, and is easily accessed by everyone else who needs it over the network. Tech support is a little sketchy. Rather than having easily contacted tech support people, there's a lot of do-it-yourself online information including information from other users. While I am comfortable with this, many new users or users who are attracted and comfortable using the very easy interface, may feel intimidated wading through all the online information instead of speaking with a customer service rep. UPDATE: Hard Drives Fail. Recently had a single hard drive fail and had to replace it. The Synology Diskstation made the exchange ridiculously easy. As I described, above, I have made NAS solutions from repurposed desktop systems, building them with multiple hard drives, and setting up the RAID, myself. This is where the Synology Diskstation really shines: Exchange of drives was nearly effortless: Rather than disassembling the box, unscrewing the mount for the drive, replacing it, screwing the mount back into place, formatting the disk, and adding it to the RAID Array -- The process in the Synology system was a matter of extracting the drive, popping it out of the carriage, inserting the new one, and pushing it back into the box. The system identified, mounted the Drive into the Array, and repaired the Array automagically. I'm perfectly capable of the whole DIY process, but it takes a good half-hour what with the disassembly process. Exchanging Drives in the Synology Diskstation took about three minutes, tops. And that included removing the new drive from the ESD bag it ships it. This was ridiculously easy; the most difficult part was remembering where I stored the key that unlocked the Drive's mounting bracket on the front of the unit. ... show more

  • I'm only scratching the surface on this but I am incredibly impressed so far.
How have I never had a NAS before? I mean, I did once but it was a LaCie and I stopped using it because it wouldn't back up to the cloud... then I tried PogoPlug and that was a disaster..... This is amazing. I have OneDrive through Office365, Dropbox free, and Amazon Drive (1TB option for now). All my videos in my iTunes library are on Amazon drive and my Windows files are on OneDrive. The critical files are on Dropbox because it has been the most reliable. With the CloudSync app that I could install on this, I can sync all those files offline onto my NAS, add new files to it from my desktop PCs, and they all back up to the cloud as a secondary source. I have 100Mb down and upload speeds so using a 100Mb connection from the PC sends it to the cloud almost as fast as I can write it there. Plus, I can turn my PC off after loading my videos and the NAS takes care of it all. Now, I also installed Emby on this and linked my Amazon Drive folder where the iTunes movies are and now I can watch my movies and TV shows (non-DRM ones, though) to my XBOX One. It's like Plex since Plex doesn't work with this device, but it didn't take long to set up. I just had to assign Read Only permission to the network so everyone can read the videos at home which let the XBOX see it. (it's still hidden on the internet, so that's a plus). Virus scans are done on the NAS and many, many other things I haven't fully explored yet. BUT my main reason for buying it was that I saw it on Know How on TWIT.tv and just had to have it for everything. Now it only has 1 bay for a 3.5" hard disk, so I put in my existing 2TB drive which is more data than I have now, so that will do for now. I'll figure out what to do later on when that fills up. But this is a really impressive device that syncs to the cloud services I have to give me an off-site backup, I can back my PC up to the NAS which backs it up to the cloud, and now I have a home media server. I only wish I paid the extra $100 to get the 2 drive array to do a RAID 0 (which isn't recommended but the offsite backup saves me if the drive fails). And for those of you who probably can't figure out how to set this up, it was incredibly easy to do. I put in a drive and turned it on. Took about 2 minutes. Once on, it blinked for a bit and then came up with a web page on my PC once I found the IP address through my router. I answered the on-screen prompts and started from there. Watch the Know How episode on twit.tv to get more information on shares and other things as they explain it well. So, I'm only scratching the surface on this but I am incredibly impressed so far. ... show more
