As my iTunes folder and iPhoto folder continue to get larger over the past year, I've notice an increasing number of problems leaving the data folders on the Synology.

I recently purchased a Thunderbolt drive to move these two data folders to them to gain speed, and the speed gains are significant. For this reason, I wouldn't recommend putting these data folders in the Synology and access them via NAS.

The Synology is still a powerful workhorse, but it is now reserved file-sharing only. Still highly valuable in that role as I have a lot of data and multiple computers accessing it.


I've been reading some negative reviews about the Synology, and while I have been really lucky, I can imagine that many setup types might not be ideally suited to the synology design.

If you've read some reviews, and are interested in the link aggregation piece but nervous because of the bad reviews, here's what went through:

Initially, i tried plugging both ethernet ports and connecting the two cables to an unmanaged switch. This caused me some issues, and then i realized there is a port bonding that needs to occur. I did that thru the synology interface, but it didn't bond proerly. I then just un-plugged one of the cables and everything worked great.

As i wanted the 802.3ad feature to work, i then purchased a cisco gbit managed switch with 802.3ad. Plugged everything in, and still couldn't get it to work right, until i realized u have to bond the ports on BOTH the switch and the synology. Now, everything works. Bonding is pretty easy, just a few clicks in the synology interface and the same in the cisco interface.

Best NAS I ever had my hands on. I am replacing my HTPC with this NAS to save some energy (400 WATT HTPC against 50 WATT NAS) and my first try was NetGear ReadyNAS and even it was a great unit, it destroyed my data volume when powering the ReadyNAS off. This was because I used new, just released 4TB Hitachi drives and the netgear ReadyNAS 5 HDD unit had problems with it (firmware bug). Than I tried Drobo NAS and it worked right out of the box but I was missing all the features the Netgear ReadyNAS has to offer and in addition the Gigabit Ethernet (DROBO E)was super slow (20 MB/sec max) what made it impossible to stream Blue-Ray files.
Finally I found my little superstar! The Synology DS1812+ is incredible. It is fast, feature rich and rock solid.
I have now 6 x 4TB Hitachi drives in it and keep expanding. I highly recommend this unit and advise to stay away from the mid-level products if you planning to really use your NAS. You get what you pay for. I am a big happy customer after returning all the other units.

I really wanted to leave a glowing review regarding the quality of the hardware and the industry leading software. Unfortunately, I have had two units fail on me. The first experienced the blue LED issue, more on that below. The second unit was RMA'd to me by Synology, and that one failed to boot 99% of the time. We think it was a power supply issue, so I guess that was just bad luck. The third unit (2nd RMA) turned out to be rock solid and stable.

The first batch of units produced were highly susceptible to a common issue. Synology eventually acknowledged the issue and stated it was due to flawed flash memory chips. They assured their customers the problem was contained, and that no future shipments would be affected. I had one of the original units that were affected, and I requested an RMA. Eight days after I reported the issue, they shipped me a new unit. I received that unit exactly a week later.

To their credit, the migration of my old drives was fairly straight-forward. There was no data loss, and I was back online in a couple hours.

The next day, the unit was no longer running. I tried booting it, but each time it would automatically restart on its own before it came online. This turned out to be a bad power supply.

My third unit came in and has been running great. I now have four drives, all Seagate 3TB, model ST3000DM001. They have good acoustics and performance so far, and temps are 34-41C. I put two drives in bays 1 and 2, and two more in bays 5 and 6. Staggering the drive bays seems to have good results with airflow and cooling, and I can fill in the gaps down the road.

I have to say, the software interface is top-notch and the box itself is very slick.

What can I say? My expectations were more than met with the Synology DS1812+. This is an amazing piece of hardware. It's small, sleek, quiet, well-built, capable, and loaded with more functionality than I could ever dream of using.

I bought mine from Amazon along with an extra 2GB stick of RAM (Kingston ValueRAM 2GB 1066MHz DDR3 Non-ECC CL7 SODIMM Single Rank x8 Notebook Memory) and four Seagate 3TB Barracuda hard drives (Seagate Barracuda 7200 3 TB 7200RPM SATA 6 Gb/s NCQ 64MB Cache 3.5-Inch Internal Bare Drive ST3000DM001). Everything came packaged very well.

Physical setup of the unit was a breeze for the most part. Installing the extra memory was as simple as removing six screws, a cover, and popping the stick into an easily-accessible memory slot. That took all of five minutes. Installing the hard drives was also simple. You simply slide a hard drive into one of the eight provided drive cages, screw it in with four manufacturer-provided screws, and slide the cage back into the NAS. That took about 10 minutes. After that, you plug the unit in and begin the installation process.

One of the only problems I encountered was with the installation disk. For some inexplicable reason, my computer could not read the disk that came with my DS1812+. The disc wasn't damaged as far as I can tell, but still my computer could not read it. No big deal, as you can just go to the Synology website and download whatever software you need, which is what I did. The installation process after that was pretty simple. I used an online Synology wiki guide to help with each step, and I was done in about 30 minutes. At first I had a hard time connecting the NAS to my home network, but after powering down the unit and powering back up, I was good to go.
