Summary: After several devastating HDD failures, I caved last year and bought this standalone machine that could perform RAID5 for less electricity ($$) than a RAID setup through a PC. That was the primary reason, but I soon learned all I had been missing out on in the years I did not have a home networked storage device. The DSM software that runs on the DS431j (currently at version 5) has a ton of bells and whistles that make this model even more worth it's substantial cost.
Summary: First off, I am a do-it yourselfer for all things computer related. I normally don't like paying for others to build things that I can just as easily do. I bit the bullet on this NAS after doing some cost analysis and am very glad that I did. Setup is about as easy as it comes. I see no reason for instructions but they are included and clear. I slapped in 4 WD 4TB Reds, powered my Synology DS413j on and was building my NAS within minutes.
Summary: Outstanding product. If it looks like it will solve your storage concerns, get it, you won't be disappointed.
Pros: No issues whatsoever. This was plug and play essentially with minimal set up. I had no experience at all with NAS or servers and was easily able to get this up and running with 4x WD 2TB red drives. The set up has been in use for just about a year straight with relatively light usage overall, but has never given me a problem. The system application/admin panel that comes with this is very good. It has many features that are beyond the scope of my intentions for the sy...
Summary: I have been dealing with large storage arrays professionally for years. I've always run at least one "server" at home, and a few years ago decided to build my own NAS functionality. I spent a small fortune on 2TB drives, a giant case, and PCI SATA boards. I put up with a noisy, always on server in our small apartment that couldn't easily be rebooted into other OS'es (after wonkiness with virtualization).
Summary: Overall, I'm absolutely delighted with this device as a home/personal/small group server. There are things that definitely be improved, but it's still a marvelous little 'prosumer' product. If you have an extensive legacy video collection (not H.264) some of the higher-end models can transcode video for you for streaming to set-top boxes like the Apple TV.
Pros: An exceptionally rich feature set. Shared network drives and RAID, of course, but also streams H.264 video to numerous devices like my Apple TV, can record and stream TV (if you add a compatible USB TV tuner), act as a network print server (if you have a compatible printer), record and monitor webcams, provides private 'cloud' style storage, backups for your various PCs/Macs, and much more.
Cons: Interface can be a bit sluggish, but is remarkably user-friendly (essentially a minimal 'Linux' desktop presented through your web browser.) There is still definitely room for improvement (for instance, I don't care for the insistence on double-clicking things as if it were a native desktop environment.) I would strongly advise the design team to curl up with an iPad for a few months to get a feel for highly polished consumer-friendly UI design.
Summary: So much more than your simple, standard NAS. This thing is amazing. I got 4 4TB WD red drives and it set up over a day or two. No worries for me cuz I went out of town for Christmas while it was formatting/verifying/etc. The UI is polished and intuitive. I was very impressed. Added the Download Station from the package manager and it works perfectly. Even downloaded the apps onto my Android so I could pause torrents with my phone while I browse the internet.
Summary: I was in the market for a home-grade 4+ bay NAS that wasn't rack mounted. After about a month of researching and reading reviews on various NAS, I finally settled on this unit. Setup was easy, if a bit time-consuming. Being one of the "cheaper" models, the drives are not hot swap, so you need to take the cover off, remove a drive tray, screw the drive to the drive tray, put the drive tray back in, and then screw the drive tray to the chassis.
Summary: After experiencing a crash that took away 6 months of hard labour, I decided to buy this model of NAS for my home. After installing I slowly learned that it is basically a full fledged server not only for a home but any small business. I installed 4 3TB drives and organized them in the proprietary SYNOLOGY RAID giving me 8.05 TB of one disk fail protection.
Summary: I upgraded from Synology's 212j to this 413j for the 2 extra bays. All the software and setup was as simple as the 212, just bought two more drives, slapped them in and hit expand volume. Took about 36 hours to format and expand but I wasn't in a rush and it did everything on its own. This product is great for my home media server for movies music and pictures.
