Big, scalable storage for all your files
Synology DiskStation delivers massive storage capacity for all your files and important business data. As your storage needs grow, simply scale up capacity by adding an additional storage expansion unit.
Powerful performance for business needs
Featuring a quad-core CPU, hardware encryption engine, and flawless software integration, DiskStation boasts outstanding processing and file transfer speeds.
Protect your data and accomplish more
The intuitive interface allows you to share and synchronize files, manage the office network, and collaborate seamlessly all while maintaining complete control over your data.
- Quad-core 2.4GHz CPU
- 2GB DDR3 RAM, expandable up to 6GB
- Scales up to 15 drives with two DX513 expansion units
File sharing and syncing
With comprehensive support for network file sharing protocols — like CIFS, AFP, NFS, FTP and more — DiskStation allows the entire office to centralize files and collaborate on projects. Or synchronize files across multiple devices or even across several locations so remote teams can work together.
Bulletproof backup and disaster recovery
Your important files deserve a comprehensive backup plan. Back up files from Windows or Mac PCs to DiskStation, and then add an additional layer of protection by replicating data to another Synology NAS, off-site server, or even a public cloud storage service, like AWS, Azure, Dropbox, Google, and more.
Storage for virtualization
With support for VMware, Citrix, and Microsoft Hyper-V, DiskStation serves as a seamless storage solution for virtualization environments. Consolidate storage in one place and enjoy optimized performance with support for iSCSI & NFS, SSD caching, VMware vSphere 6 & VAAI integration.
High availability and business continuity
By combining two DiskStation servers into a single high-availability cluster, you can maximize uptime and ensure data and services remain available for your employees or users — even when one of the servers goes offline unexpectedly.
Rest assured your data remains safe and secure
DiskStation offers an arsenal of security enhancements and tools to safeguard your data from malicious or snooping parties. You can analyze network traffic, detect potential attacks, and block threats with Intrusion Prevention System (IDS), firewall, auto-blocking, and more. Audit configurations, detect weak passwords, and ensure the system remains free of vulnerabilities with the built-in Security Advisor. Lock down data storage and network communication with sophisticated AES encryption and SSL certification/Let’s Encrypt tools.

Top customer reviews
- easy drive install and basic setup
- compatibility list for drives
- very good software with frequent updates and good package expansion options
- good company reputation, barring that one hacker incident a few years ago
- smaller than any equivalent PC case+motherboard combo that will operate 5 SATA 3.5" drives in RAID
- power cord was longer than most bundled power cords, making placement easier (though the ethernet cables were pretty short)
- expensive for the hardware you get - you are paying for the name (e.g. 2GB of RAM at this price level is weak)
- 2x80mm fans are noisier than most 90/100/120mm fans, which is weird because there are smaller 4 bay Synology boxes with 90mm fans
- drive trays feel flimsy, are plastic, and have no noise/vibration dampening
- no list of approved RAM upgrades other than the Synology direct one (add 4GB for about 100 bucks)
- no case noise insulation either, presumably in the name of ventilation, so the 5x WD Red drives are very audible during read/write
- some security and typical settings are either defaulted off or should be asked during initial setup - you can go back and pick them in control panel later, but they seem like they should be more visible (e.g. what's the name of the Windows workgroup to add the machine to? Should https be used for the admin interface? wake-on-lan enabled?)
- when setting up drives you cannot choose volume labels - it turns out the share folders inside the volumes are what are externally visible to clients, but that's not obvious at the time - it seems like you are going to get a thing on the network like "\\servername\Volume 1" instead of \\servername\photos or whatever.
- one of my fans was defective - made a clicking sound constantly, from inside the fan motor housing (the blades were not hitting anything); the noise was actually worse in quiet mode than in cool (hi speed) fan mode, and updating all the software to the latest versions made no difference
- installing the photo app from synology triggers a multi-day disk activity flurry while it builds thumbnails and indexes your images - there's no warning of this beforehand, and the message when you did into the active process says your image files are being "converted" which is scary
- not sure how their competition does it, but it seems like it should be possible to use the 4 USB3 ports on the back for external drives added to the RAID array, not just as backup and temporary share folders, or the product description should explicitly say they cannot.
After I made sure everything was basically working and the unit wasn't DOA, here's what I did to minimize the bad and ugly:
1. Replaced the 2GB RAM with this 2x8GB RAM kit (search youtube for a video on how to).
Will have to swap back in case of an RMA, but in the meantime it's working fine and I have 16GB, and about 14GB shows up as cache in the control panel. And it costs half what the Synology upgrade to 6GB does.
2. Replaced both noisy fans with quieter ones, getting rid of the clicking from the broken one and lowering the overall noise level.
My one gripe is something that many people would not care about, but it is a problem that should be easy to avoid or fix and yet it exists. When you create a Disk Group or a Volume, it is automatically named by the box (Volume 1 for example). The next one is automatically named with the next number (Volume 2). The name is based on the lowest number not already taken, so if a Volume or Disk Group is removed then the next one you make will take its name. You cannot select the name or rename after the fact. The defense I've heard for this online is that the end user never sees those names so it doesn't matter. Well I see them every day and it matters to me. I have to decide what gets copied, backed up, or deleted, and it would be nice if my groups and volumes could have names that make sense. As a result of things being created as blank disks were obtained and data was migrated, I have ended up with Disk Group 1 containing Volume 2, and Disk Group 2 containing Volume 1. When it's possible to wipe out an entire company's data if you get confused, having this kind of situation is not helpful. I think part of what makes it so frustrating is the fact that they got so many other things right (pretty much all of them) that I can't believe that this detail is not better. I expect this will eventually be remedied and at that time I'll add that star back.
Summary: If you're not a picky little baby like me, this thing is perfect. If you are like me, then it's only almost perfect.
UPDATE: October 2016: I bought another and it came with DSM 6, which resolves the problem I complained about above. It has a lot of other improvements, but maybe a few slowdowns. It's hard to compare because I am using two different devices. I'll update with when I upgrade the original DiskStation. Bumping this up from 4 to 5 stars.
