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.

2 out of 5 eggsTime backup doesn't work

Pros: Quiet enclosure

Cons: A research lab in the university I work for bought two of these units, one to be used as a primary NAS and the second as a backup destination. We have been working with Synology support for several months now trying to get the Time Backup feature working. It simply does not work, and their developers in Taiwan are unable to determine why.

Other Thoughts: I would not recommend Synology NAS units for any data that is important or where the data is expected to be reliable.

One of my consulting customers also has a Synology NAS, and just moments ago the primary volume crashed (prompting this review), interrupting work I was going to do this weekend. Thankfully the unit was only used as a backup destination.

5 out of 5 eggsWorth the price

Pros: Robust feature set. Long-term maintenance appears to be easy. The Synology Hybrid RAID setup makes volume expansion a no-brainer. Synology support is responsive. The underlying OS is updated regularly.

Cons: Trays are plastic. Disk retainers on the trays are also plastic snap-in inserts. There's very little actual metal in the parts a user would operate. No option for dual power supply. 4x LAN ports but no native link aggregation.

Other Thoughts: Make no mistake - this unit is expensive. If all you need is a NAS repository, you can find less expensive options. But if you're going to customize a small PC as a NAS with additional services (*nix/Mac/Win shares, DLNA media server, etc.) you'd be wise to consider this unit. A small PC might be cheaper up-front, but the long-term power costs will eventually make that option more expensive. This thing sips power - barely more than the disks it hosts. Much of that is due to the elegant design utilizing a dual-core Atom CPU. There's 2GB of RAM soldered to the board with the option of adding a 2GB SODIMM module. It's a DDR2-1066 module, but the requirements are quite specific. Be sure to check Synology's website for the exact requirements.

Thankfully, this unit handles problematic disks that normally don't like RAID, like WD's green line. If you've got a pile of them sitting around, the Synology unit can put them to good use as a group.

Another thing to remember - when expanding a volume configured for Synology Hybrid RAID, you'll need to supply a disk as big (or bigger) than the largest disk already joined to that volume. So start with your smallest disks and expand up from there.

Lastly, I tried connecting some 4-port eSATA enclosures to the Synology eSATA ports since they use a common Silicon Image chipset. However, it recognized only the first disk. There must be some "secret sauce" in either the base unit or the DX513 units to allow the port multipliers to work properly.

5 out of 5 eggsSynology

Pros: Let me start by saying you get what you pay for. There are a lot of systems out there ..yes you can build your own maybe for less. With this system your paying for the software and synology brand. I've had a few models of the synology NAS devices and I couldn't be happier.. 4 NICs I bonded them into pairs on two different VLANS on my home network everything is working smoothly. no complaints.

Cons: Yes a little pricey ...but try and build a comparable product ...(RAID card,motherboard, software,hot swappable drives...etc) your gonna get up there in price... even before you start thinking about the Hard Drives... There is a learning curve as far as file permissions. Depends on what you trying to do on your network! Google is your friend answers are out there...just search.

5 out of 5 eggsVery Impressed

Pros: Very Fast
Low Power
Easy to set up
4 Ethernet Ports can be linked together
Nice User Interface
Can be expanded with additional expansion units
Whisper Quiet
Different RAID Options
Easy to set up shares and permission
Integrates well with Windows Environment

Cons: Price - The price of this is a little steep
Some of the user interface items are not intuitive
Setting up Link Aggregation was easy to do but not immediately apparent on how to do.

Other Thoughts: I've built several RAID Systems over the years and now that it is about time to retire them I decided to give one of these a try and I am very impressed with it. Setup was easy, from out of the box to inserting the drives (which is does not require any tools for 3.5" Drive) I was up and running in less than 30 minutes.

When people say these are fast units they are not kidding. I am seeing just under 900mb/sec transfers from one of my systems to the NAS with four 4TB Drives. That is just about 3 times faster that my old RAID System using a 3ware / LSI Caching Controller.

I like the fact that this is expandable with the additional expansion chassis but they are really pricey. To get a total of 18 Bays (with two DX513's) you are looking at a total of $2k plus but understand that it is an incremental process.

The Link Aggregation / Bonding is a really nice feature and for some reason it wasn't obvious to me how to set it up but a quick search online and I was up and running in no time.

4 out of 5 eggs

Pros: * Low Power
* Quiet
* Great web based management software
* Lots of useful software packages
* Build on top of Linux
* Lots of room for expansion with several disk configurations
* Matte body that doesn't pick up fingerprints
* 4 Ethernet port with support for Link Aggregation

Running with 6 Western Digital 3TB Red drives in a RAID 6 configuration, my average transfer rate (reading or writing) is around 110 MB/s over a single Gigabit Ethernet connection.

Cons: * Software configuration is spotty in some areas (see Other Thoughts section)
* Very easy to prevent the system from entering a low power mode
* Disk trays and guides are plastic, which feel a bit cheap. Not really an issue since swapping disks should be uncommon.
* First unit I received had a faulty fan controller (one fan would never spin up). After a Newegg RMA, I haven't had a single issue with the replacement.

Other Thoughts: I had originally considered building a Mini-ITX based PC to act as a server, however I opted to buy the Synology since it:
* Uses less power than anything I could configure
* Offers lots of hot-swapable drive bays
* Has a mature software suite
* Offers Link Aggregation for when I update my switch

The unit was setup to do two primary things:
* Act as a central file store for my network with some form of redundancy
* Host a code repository

As a file server, the unit has been great. I haven't had a single issue transferring files locally with Windows or Arch Linux. Additionally, the unit provides plenty of options to access the data remotely (FTP, SFTP, HTML, VPN, and a few others).

In terms of code repositories, GIT and SVN are supported. I primarily use SVN so my I cannot comment on the GIT support.

Configuring and setting up the SVN server was very straightforward from the web management interface. Locally everything ran great. Unfortunately, there were no configuration options to access the SVN server via HTTPS. After doing some poking around via SSH, I was able to manually bind the service to the running Apache server.

I also messed around with hosting a E-Mail server with SpamAssassin. Again, the initial setup was very straightforward; however, the software had a undesirable side effect: the system would not enter low power mode.

SpamAssassin will constantly check a folder for new mail (default config of once every 5 seconds), which kept touching the disks, preventing them from entering hibernation. Upon discovery of the issue, I opted to remove the mail server to prolong the life the hard disks.

So, while the initial setup of the unit was simple and straightforward, there are several little gotchas hidden throughout. Frankly, I consider HTTP access to SVN to be a common use case, and enabling supported software should not constantly hammer the disk drives.

If you are comfortable with working with Linux from a SSH sessions, then the above really isn't an issue. Otherwise, I'd recommend you check out the live demo of the DSM (the web management interface) on the Synology site to determine if the unit will meet your needs.

5 out of 5 eggsEggcellent

Pros: * High and expandable capacity NAS. I really like the case. Installation of drives was really simple.

* Hot swappable drives

* Can increase capacity by merely inserting new drives

* Nice software/web user interface

Cons: * Price

* Getting this thing up and running on my LAN took way longer than it should have. The installation instructions said that as long as the NAS and my computer were connected to the same LAN all that would be necessary to install the software would be to navigate to and then follow the instructions on that site. But that site didn't find the NAS. Thankfully the manual pointed me to where I could get an application that would help install the software. Then, because of a missing instruction in the manual, it took me even longer to get this up and running. But now everything is working well.

My only complaint, not with the NAS but with my LAN, is that I'm only getting 10MB/s transfer rates. Time to reconfigure/upgrade my router.

Other Thoughts: I installed 5 Seagate Desktop HDD.15 ST4000DM000 4TB 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drives into this machine and configured it to use the Synology Hybrid Raid. It took more than 24 hours for the disc analysis and raid configuration to complete. But I'm happy that no problems were detected with the drives. So after a quick delivery from Newegg, a long installation and slow configuration, my system is up and running with more than 14 terabytes capacity. I still have 3 free slots in this machine and I'm a happy customer.

5 out of 5 eggsPrimo Backup System

Pros: Simple to use on Apple or Windows products and Linux as well.
Inserting drives requires no screws (but they come with the unit if you want to use them).
Works with Time Machine
Ample USB 3.0 and 2.0 ports
4 network cards (although I haven't figured out what I'm going to do with them)
Dual Fan
A ton of software available, including myPhpAdmin, iTunes Server, and a million others.
Beautiful Web client based desktop Linux/Windows like
FTP, Telnet, NFS, SMB, AFB, all that
Great Management Tools
Awesome storage capability and expansion
More services than I will ever use
The CPU and default RAM (2GB) seem more than enough for one or two users. I haven't seen either being put to the test. Don't run out and buy more RAM just yet. This unit is efficient!

Cons: I'll have to be picky here. More of a wish list.
No USB ports in the front
The disk trays are plastic and a little flimsy. They work of course, but metal would have been much nicer and easier to manage
Software does not have quotas for individual folders. All quotas are user based. (Future software release maybe?)
Would have liked to see more one-click updates. For instance, to install/upgrade Java, you have to find the right file, have an account with Oracle, all doable, but a hassle.
No calibration of fans. Unit basically has two settings. One for quiet and one for cooler. I have a warm room and the drives are at 95 degrees F, on the cooler setting. I actually would like to spin the fans up a bit more, as cooler is better!

Other Thoughts: I bought the unit with 4-2TB Seagate drives, giving me 3.5TB usable space using SHR-2 RAID. Nice to know I can pop in more drives, bigger drives until I reach crazy limit. With the price of the unit, 4 drives coming in around $1500-$1600, I figure I'm paying around a dollar a day for my data redundancy/backups, if I get 5 years out of the unit. Now if only the price of tape drives and tapes would come down! This is light-years ahead of the ReadyNAS I bought years ago. And I paid around a grand for that unit with only 1TB of storage.
