Unlike many other companies, Synology doesn't artificially cripple their models depending on their cost for the most part. The j series model has all the same features from file sharing, video sharing, IP camera recording, etc. The two things which change between the series are the CPU/RAM and external ports.
As a j series model the DS413j has only the basic 2x USB 2.0 ports and a 1.6 GHz ARM-based CPU. Moving up the line you start to get things like eSATA, USB 3.0 and SD card readers. The highest end models have either PowerPC (Freescale) or Intel Atom CPUs. Do you need the faster CPU? If you're just using it for file serving, etc. No. You probably don't. If you're going to use the NAS for either photo viewing or video transcoding - yeah, you might want to spend the extra money as the lack of a floating point unit makes image thumbnail generation really slow on the ARM CPUs and some transcoding packages are only available for the x86 Atom chips.
As for the ARM chip and 512 MB of RAM in this model, it's pretty easy to max out the processor doing a couple things at once, but it doesn't really slow things down. Under normal use you won't notice it. The RAM is rarely full past 40% or so.
-Supports many RAID types (0, 1, 5, 6, JBOD, Synology's own RAID, 10, etc).
-DSM has a great interface and tons of features.
-Very quiet, cool and well built.
-Great iOS support. Can view cameras, photos, videos, files, system info via apps.
-DSM supports USB wi-fi, digital TV dongles*, printers, hard drives.
The Not So Good:
-*The DTV dongles supported are NOT compatible in the US/Canada. Overseas only.
-External hard drives can't be added to a RAID or shared normally.
-HFS/HFS+ drives are STILL not supported!
-Synology charges a lot of money for additional cameras past 1 (around $60 a camera!).
The good news about the bad stuff is most of it can be added/fixed with software updates.
I've had it for a little while now and still no problems. The more I use the iOS apps, the more I find they're pretty limited (I haven't tried the photo/video/music ones), but the administration one is quite lame - it's basically a system info. Even the mobile web interface is pretty much a list of settings with no way to change them.
The DS413 is now listed on Amazon for a less than $100 difference. In hindsight I would probably have gotten the DS413 over the DS413j. Why? Double the memory - although it is rarely used in my day-to-day tasks, I suspect it is the main limiting factor when new OS updates come out. I wouldn't be surprised if the extra $100 gets you one for version than the j (getting cut off at DSM 7.0 instead of 6.0 or whatever).
One thing I did notice, however, is the blue power LED is -insanely- bright. It might as well be a flashlight!
The performance is great when plugged into a gigabit network, I get great write an read speeds. The only complaint on accessing files when the unit is waking up from "hibernation".... SLOW wake up time. For a quick sec you wonder if you PC is connecting to the drive or thinking about connecting. Once it wakes up and the drives start spinning it is off to the races!
With ANY NAS software is the key. Synology's DSM 4.1(Disk Station Manager)is what separates this NAS from other products. They also have great iPhone and Android apps that let you access all your files from you phone or tablet. This NAS lets you create your own cloud and it works! QNAP makes good stuff, but for easy of use and features I am sticking with Synology. A little pricey compared to other NASes, but I am glad I spent the extra money. I was going to build a NAS with FreeNAS and an old PC, but the thought of burning electricity all the time made me spend the money on the DiskStation DS413j.
Would highly recommend.
The reason I bought this was that I had all my collected videos, software backups, etc. on a 2TB drive I'd added to my computer. It was nearly full and I had no backup for it so if it failed all would be gone. Over the years I've had many drives die so I know it is always a matter of when not if.
I've read all the reviews and Synology and Qnap are always at the top. I like the Synology Hybrid RAID (SHR) which uses standard RAID but allows you to utilize different sized drives and upgrade to larger drives at a later date. The Disk Station Manager (DSM) software is great. DSM is a web based OS that you access with your web browser. You don't need to install anything on your computer.
When I purchased the DS413j I also bought two Western Digital 3TB Red drives. The Red drives are a little more expensive but my hope is that they should have a longer life. I also threw in a pair of 500GB Green drives that I had been using for backup purposes. I don't know that Western Digital is any better or worse than the other brands but my experience with their warranty dept. is what sells me on them. If a drive does fail they make it super easy to get it replaced.
Setup was very easy. Just install your drives, plug the included Ethernet cable into your network, turn it on and log in using your web browser. You'll download the latest DSM software and go through a simple setup walk-through. Note that any data on your drives will be erased as they will be reformatted during the setup process. SHR will be the default choice but you can use any RAID settings you desire. In a matter of minutes you will be greeted with the DSM desktop where you can start playing with all the features of your new Diskstation. Note that performance will be significantly reduced for many hours as a background check on all your disks is performed. It took over a day for mine to complete but I was already transferring files which I am sure slowed down the process.
I was disappointed to find out that the print server doesn't allow for two-way communication. I attached my inkjet printer to the Diskstation's USB port and found it easy to set up. I can print just fine but get no data back from the printer about things such as ink levels.
My main use for the Diskstation is movie storage. DVDs are a pain to deal with. I've been ripping all my DVDs and saving them to my Diskstation. I use my Tivo to watch them on my TV using the free PyTivo software. Currently I have PyTivo running on my PC and accessing the files on my Diskstation. I have read that people are running PyTivo on their Diskstations but I haven't tried it yet and am a little concerned that the CPU in the DS413j might struggle in transcoding video.
As far as speed goes I rarely notice a difference when dealing with files on the Diskstation over files on my PC's local drive. I get average real world transfers of 35-40MB/s over my gigabit network.
Overall it is a nice little unit. I am glad to have the added security of RAID so that if a drive fails I can replace it and not lose my data. I am aware that RAID isn't a substitute for a real back up but it is much better than storing files on a single disk that isn't backed up! When I win the Lottery I'll get a second Diskstation to back up my first one to.
