    My first NAS, May 10, 2016

    Before you buy: google “DSM demo” and select the first result. They have a free trial of what using the NAS is like, (with a few caveats of course). You can use the interface, use some of the packages, look at the options. It’s a touch slower than my own NAS but otherwise very indicative of the end user experience.
    ——————————————————————————————-

    I bought this with the intention of decluttering my computer’s HDD and for sharing my movies and things with my roommate, and for this purpose, it works brilliantly. But it has far and away exceeded my (admittedly naive) expectations.

    Hardware:

    I’m a huge fan of SFF things, especially with computers. This NAS is amazingly efficient in terms of space utilization. As a fan of design, I give them a huge thumbs up here. With the drives out you can see everything inside, and they don’t waste a single milliliter of space. Everything has a use from the structure, to the PCB, to how they’ve tapered one edge to make the power button and LED on the side fit nicely while still fitting with the exterior design language! There’s a fan for the drives, and it’s user-replaceable! Seriously, this thing has a winning design.

    The tiny PCB packs a relatively low-power 1 GHz dual core ARM processor which is how it gets away with such little cooling in this form factor. As far as how this impacts performance, I don’t have another NAS here to compare it with. I will say that if I was given the interface and had to guess the speed of the device, I would not guess that low. I guess that’s the magic of first party hardware and OS.

    The only very minor gripe I can throw at them: why do I have to label my drive sleds? Synology only provides 4 stickers and sleds anyway, so it’s not like I’ll be swapping them out. The stickers are tiny; I would have preferred if the labels were just embedded on like they are under the bays.

    As far as the drives I’m using, I have 4x Samsung Seagate 2TB Laptop HDD SATA III 2.5-Inch Internal Bare Drive 9.5MM (ST2000LM003) in mine with a RAID 5 config. No problems with noise, but I have mine on a shelf in my office. If it were on my desk right in front of me, spinning 4 platters at once, I’ll hear it, but that’s what I get for using HDDs. Under normal conditions I cannot hear the device when it’s in use only a few meters away.

    Operating System:

    I’ve thoroughly enjoyed using this. The DSM OS has a nice Unix-like feeling, its got lots of options for configuration and access. I don’t know what I expected, but its essentially a low-power server, which is awesome. I usually dismiss any service that claims to have an “App store” but this is a new product category for me, and the package center has a compelling selection. I am able to control the access of all the users, because I’m literally the sysadmin. It has unix-style system permissions, for users and groups with folders and files.

    Packages:

    This is where the device really sells itself for me. I bought it thinking it was just a storage box, but these packages have changed how I use the device. Here’s a list of some that I found pretty cool:

    – They have a first party suite of packages for managing media like movies, music and photos. I use the Video Station package the most and it makes the viewing experience remarkably easy. There’s a web portal for desktops, and of course apps for both iOS and android which work pretty identically to each other. Video Station can stream playback to lots of devices, DLNA, Chromecast (I can only do this on the mobile apps, not the web interface for some reason), and even Apple’s own airplay. It’s not perfect, but it’s really good.

    – Developer tools like Python, Java, Ruby, and even a first party Git server, which I think is pretty neat. There are a few cases where I could see myself using my own personal git server, and I’ve downloaded it but haven’t had the need to use it yet.

    – A seedbox style download manager. I’ve used this to download an OS disk and it worked splendidly, it’s a set it and forget it kind of thing, just like regular torrenting. But what’s more, I could be at work and pull up my NAS desktop and check on the status, add more, the works.

    There’s loads more that I haven’t even been able to use yet. A personal VPN, a security camera suite, Wikis, moodle, backup managers, cloud backups (which I think Synology hosts themselves, don’t quote me on this), etc. I recommend you look at the full list on their website before you buy, (google “DSM packages” and its the first result).

    A little note here, when messing around with some of the packages, I downloaded PLEX to try it…

    annoying whining noise coming from circuit board (fixed itself!), April 21, 2016

    Annoying whining noise coming from circuit board. Is definitely not fan noise, and was not coming from installed hard drives (I was using ssd’s). The sound resembles a faulty voltage regulator, which it may well be.

    I have asked for RMA, but it has not been approved yet…they want me to escalate it through synology’s support site first. i’m skeptical that a noisy circuit board can be fixed with a config setting or OS update, but i’ve seen weirder things happen so i’ll give them the benefit of the doubt for now. Their support site says there could be a delay of 3 to 5 working days before i get a reply.

    Will adjust review as the case progresses.

    Update 1. Whining noise decreased when I unplugged ethernet cable. That’s nice to know, but a NAS is kind of designed to work with the ethernet cable in place, so that’s not really a viable solution. Tried other cables and plugging into a different ethernet switch, no improvement.

    Update 2. While I was experimenting with the ethernet link as a source of noise, I picked up and set down the unit a number of times. I did this reasonably gently and was just trying to get better access to the rear of the unit, where the ethernet port is. When I was done with trying out different cables and switches, I noticed that the noise had decreased. So I gave it a couple of whacks with my hand and it’s silent for now. It might be temperature sensitive. I’ll let it sit powered off overnight and update the review again after that.

    Update 3. Did an overnight with the unit powered completely down. The noise did not come back when the unit was powered back on this morning. I’ll do a couple more cycles but, bizarrely, the problem seems to have fixed itself.

    Out of curiousity I tried to find some extra caddies for this. The part is shown on synology’s web site, but you can’t buy them directly from synology. The part is list on some common internet retail sites but shown as out of stock or unavailable. I believe the caddies are the same as for previous models (DS411slim, DS414slim) and those caddies are just as hard to find.

    Update 4. After about four days the problem simply disappeared. The unit no longer whines, even after a cold overnight boot, which used to bring out the whining noise for sure. I’m not sure what to make of it. Probably a 3rd-party-supplied ethernet chip with a marginal on-board voltage regulator worked itself into a stable position after a few temperature cycles.

    Update 5. Found a place to get spare caddies/trays. web site with name similar to store synologyamerica com. $5 each, which seems like a reasonable price however some of the shipping options cost more than the part so pick carefully.

    Reliable and easy to use. Great Entry level NAS device!, April 6, 2018

    I was uncertain about getting a local storage device for my home thinking I did not really need one with all the cloud services that are out there. Having gotten this model I am very pleased with it. It works well, its very simple to set up and use. It is easy to swap out failed disks. I have managed to upload all of my old home movies that I had earlier transcribed to DVD’s onto this device. My wife an I are able to upload all of our digital photos from our smartphones freeing up space on our phones. Memories is a great app for the task of backing up your digital photo’s. Only downside to it is that I cannot seem to use a USB connection to move data from the phone to the server directly, it seems to insist on using the WiFi. As I had many photo’s and video’s to move across and because Wifi was slow and quirky on occasion I would up moving the photos to my laptop and then from my laptop to the NAS. My son also has a Synology NAS (he suggested that I get a NAS for my home). As a result I was able to share the old home video’s with him directly by syncing the two devices. We now backup each others critical data between the two NAS devices.

    The downside is that there are a few quirks to consider. Drive (synologies equivalent app to DropBox or Google drive) does not seem to work as seamlessly. Simply storing info into drive does not seem to move it to the NAS device. If I mount the NAS as a shared folder I can save documents to it and then they appear in Drive on any device I add the app to. Could be my inexperience. Moments is tied to Drive. Once Drive is loaded the more sophisticated CloudStation Server app cannot be used. Basically you have to choose one or the other (Drive or Cloudstation).

    Lastly (and this is my fault), this unit does not transcribe movie formats. So if you have a mix of formats you will need to use an external device to recode them in to a MPEG format. Here I should have done a little more research, but the workaround is simple, use your computer, using open source software and recode it and just store the recoded files.

    I am able to run video directly from my Samsung Smart TV, or an Apple TV (you need to use your phone to push the video to start on Apple TV, but once you do this your phone is no longer needed. This is similar to how Chromcast seems to work). It also works on Roku, although Roku is giving a message that the video app is not fully compatible and will no longer be available after the end of 2018.

    I am amazed how much data you can store on this device. I purchased two 4 Terabyte NAS disks, and with everything I placed on it am using less then a terabyte of storage!
