Superior Performance


The Synology DS1813+ is built for speed. With dual core CPU and expandable RAM capacity, the DS1813+ is ideal for the mission critical tasks of SMBs as well as the most intensive applications from data-encryption to video-transcoding. With link aggregation, Synology DS1813+ can deliver up to an average 352.39 MB/sec reading and 211.88 MB/sec writing speed under RAID 5 configuration in a Windows® environment¹.

Virtualization Ready

With the iSCSI support in DSM, DS1813+ provides seamless storage solutions for virtualization environments, including VMware, Citrix®, and Hyper-V®. VMware vSphere®5 and VAAI integration, DS1813+ helps offload specific storage operations and optimizes computation power for unparalleled performance and efficiency in VMware environments. It is the ideal alternative to SAN solution for businesses. Affordable and cost-effective, iSCSI allows SMB users to consolidate storage into data center storage arrays while providing hosts with the illusion of locally-attached disks.

Feature-Rich Business Applications


Put your data to work with Synology's DS1813+. With Windows ACL and LDAP support DS1813+ fits easily into any existing workgroup environment, providing detailed access control and efficient privilege settings. A wealth of SMB applications including printer sharing, VPN server, ERP software, mail server, web server, anti-virus, and network video surveillance, allows a single Synology DS1813+ to replace several pieces of traditional hardware and helps to maximize your productivity while keeping cost and effort to a minimum.

Resilient and Reliable

In addition to superior performance, the DS1813+ is built for reliability. Four LAN ports provide redundancy in the event of unexpected hardware failure while hot swappable drives also help to minimize system downtime during drive replacement. Furthermore, passive cooling technology eliminates the dependency upon a dedicated processor cooling fan. Should a fan fail, built-in redundancy mechanisms will spin up functional fan(s) to improve ventilation.
Uninterrupted availability is a critical goal for all businesses; however, many businesses worldwide still remain unprepared for disaster. Synology High Availability (SHA) can ensure seamless transition between clustered servers in the event of server failure with minimal impact to applications to decrease the risk of unexpected interruptions and costly downtime.

Unparalleled Flexibility

As your data storage needs grow, Synology's DS1813+ can grow with you. The DS1813+ can be connected to dedicated expansion units for additional storage on the fly, growing capacity with minimal effort. When paired with two DX513 expansion units² through specially designed eSATA connectors, raw capacity can be as high as 90TB.

Easy Backup Solutions


To protect your critical business data, DS1813+ can become a centralized backup target for consolidating fragmented and unstructured information across your network through a range of options. PC users can backup to DS1813+ with Synology's Data Replicator, while DS1813+ also fully supports Mac OS X®'s native Apple® Time Machine®. Synology's own backup wizard can back up information to another Synology NAS or any rsync server, with the option of using an encrypted connection, or to an external hard drive via USB 3.0 or eSATA. The wizard can also back up your information to the cloud, including Amazon® S3, Glacier, and STRATO HiDrive.

Energy Efficient Design


Synology DiskStation are designed and developed with energy efficiency in mind. Compared with the average PC counterparts, Synology DS1813+ consumes only 75.19 watts in operation. Wake on LAN/WAN and scheduled power on/off features can further reduce power consumption and operation costs. HDD hibernation can be configured to take effect automatically when the system has been inactive for a specified period of time to save energy and extend hard disk life. All Synology products are produced with RoHS compliant parts and packed with recyclable packing materials. Synology acknowledges the responsibility of a global citizen and works continually to reduce the environmental impact of every product.


1. Performance figures could vary on different environments.
2. DS1813+ supports up to two Synology DX513/DX213, sold separately.

5 out of 5 eggsGreat Synology product as usual!

Pros: Great product.
Solid build.
Made mostly of metal (drive trays are plastic but seem to be durable).
Trays are screw-less or you can use the supplied screws to mount the drives.
Quite for a unit this size.
Runs cool.
Very low power usage for the size as well.
Will do just about anything.
Synology's Hybrid RAID is the best option for redundancy (see blow).

Highly recommend Synology products!

Cons: Wished it had an option to dim the power, net and status LEDs, they are a little bright to have in low or dark room (for watching movie etc...).

Other Thoughts: Bought this to upgrade my DS412+. I needed more space to put all my externals in one place. As soon as the move is done, I will move the drives from the 412 to the 1813 to give me around 18Tb (8 x 3Tb Toshiba drives).

The hybrid RAID is what I wanted in this unit and the past units that I have owned. I have found it to be a very flexible and durable technology. I recently had a drive go bad though it was still usable. The Diskstation reported in SMART that the drive is failing. Took out the drive and replaced it with a new one and started the repair process. I love the idea that the shares can still be used wile the repair is going on in the background. Adding new drives is very easy with the hybrid RAID. You can find more info on Synology's website.

I would recommend any Synology product to anyone that needs a NAS. Even if you don't use it's full potential. There is a great community support forum that I have asked for help and have helped others with.

1 out of 5 eggsFails to Rebuild

Pros: When it works it is ok.

Cons: If a drive fails and the array needs to rebuild good luck. Always fails for me. Support is completely useless. All they recommend is backup your data. I would not purchase this item again. Do not store important data on it.

5 out of 5 eggsFantastic unit

Pros: Simple to setup, maintain, and operate. CPU handles all the tasks I've thrown at it so far surprisingly well which had me concerned at first.

Cons: Price, but well worth it.

Other Thoughts: Initially purchased to use as a Plex media server with massive storage but am finding so many more uses for it with available packages. Thus far I'm very pleased. I'm constantly finding built in features I didn't know I wanted till I stumbled upon them.
Loaded it with HGST 4TB NAS drives and expanded the RAM to max.

5 out of 5 eggsAwesome!

Pros: I operate several NAS systems from personal size to enterprise. Synology is a great, easy-to use platform and this unit is well built and outstanding value. Loaded it with 4Tb drives and shipped it around the works but it purrs away without problems.

Cons: Synology is like the Mac of NAS systems, it's very user-friendly but not nearly as open as something like FreeNAS. For most users this is a positive thing.

5 out of 5 eggsExcellent

Pros: Works as expected. I don't use anywhere near all the features on this devices but everything functions with the exception that I can't make it work with my APC UPS unit.

Cons: Wasn't free. My UPS can't control this device.

Other Thoughts: My APC UPS is on the list of devices listed as compatible but the UPS software says it isn't connected. So I have to manually shut this unit down when there is a power failure.

I have had a DS413j for over a year and ran out of space. The UPS not controlling Synology produsts is my only grip.

5 out of 5 eggsNo more Second Thoughts

Pros: Wanted the 8 bay for expansion and all of that and more. Bonding of NIC's for fail over and ability to use for iSCSI (haven't gotten that far yet, next step) are great features. Easy to manage. Logging is great as well to see who is accessing files and where. Would buy again without a doubt.

Cons: Maxing this unit out at first can be very costly. But you can get going small thanks to Hybrid RAID to safe $$ initially and add storage when needed down the road.

Other Thoughts: Great unit, very easy setup. Helps to know about permissions and already having a set plan on who gets to see what and what folders to create(backups, media, files,etc). Very powerfull and can be used as email and webserver, but I'm not using that(what the iSCSI will be used for in the future!) SMB or Home you cant go wrong with this unit.

5 out of 5 eggsExcellent Price for Performance/Capacity

Pros: - Read / Write* Cache supported with SSD drives (2 minimum)
- Multiple NICs for iSCSI multipathing
- Expandable chassis

This is on par in performance with a cheap SAN, for about $3-4,000 completely kitted out (except for expansion chassis).

* Write cache was just enabled in the last couple of updates.

Cons: - I wish they would have included the 4GB ram max instead of requiring an upgrade module. The module is only $25-30 anyway, so go ahead and include. This wasn't enough to deduct an egg, as only those using SSD cache really need the memory.

Other Thoughts: I'm running 6x4TB in SHR, and 2x128GB SSD configured in a Read/Write Cache. 3 NICs are configured in a LAG for iSCSI supporting 3 ESXi hosts configured in High Availibility and takes everything we can throw at it.

We saw 90+MB/s sustained write speeds while migrating hosts to the new iSCSI volume, but have yet to do formal testing (IOP's are more important than bandwidth).

4 out of 5 eggsSynology DS1813+

Pros: Exceptional performance. Lots of options. Up and running in no time. Sustained writes at 115kb/sec over GB LAN.

Cons: Drive Bay #8 LED did not light up. Need to RMA. Too much money to not have something as fundamental as the drive light not work.
