Buyer Beware!!! Synology will not stand by their product!
16 January 2014
Summary: Sorry for the long post, but here it goes... I have two DS212J. The main DiskStation is serial #xxxxxxxxxx, which has two 3TB hard disks (Model # WD30EFRX-68EUZN0). The second DiskStation is serial #xxxxxxxxxx, which has two 2TB hard disks (Model # ST2000DM001). This disk station serves as the backup drive to the Main DiskStation. Both units are plugged their own Gigabit Switch, (TL-SG108) with 3ft of cat 6 each.
Do not buy this if you have Apple computers and want to do time machine backups over WiFi

Summary: I escalated my issue to a manager who just ignored me. Their support was very unpleasant to deal with. Their concern the whole time was that "this guy's trying to get a refund." I only wanted to figure out how to get it working for WiFi timecapsule backups. I sold it on eBay and bought a new Apple Extreme with Time Capsule. It just works. I bought this device to replace a Dlink NAS and my Apple Time Machine backup.
Summary: So I spent all this money on a NAS with the hopes that number 1, it would be fast. However, I only am able to get about 2-3 MB/sec write speed. I get faster downloads from Itunes. I was reading in the Synology forums that perhaps previous versions of the Diskmanager software was faster, but those versions are unsupported. I also tried uploading some pictures from an external drive directly to the USB port and it has been 3 hours and it has only uploaded 13 GB.
Not a stable media server OR critical backup system. Bad product support. (Updated)

Summary: UPDATE (6/25/2012): It's even worse than my original review indicates. I've given up and have built a new media server (starting with a small "bare bones" SHUTTLE SH67H3 PC Barebone System case) and I'm harvesting the hard drives from the Synology system to use on that new Ubuntu Linux system. I'll be running XBMC (XBox Media Center -- a product not associated with Microsoft's XBox, BTW).
Summary: My DS212J worked fine for about a month and then it was no longer visible on the network. I went through all the basic trouble shooting steps (new hard drive on their compatible drives list, new network cable, different PC etc.) with no luck. All the lights are green (except the blue power button) and there is LAN activity indicated on the front, but there are no lights on at the LAN port. I suspect that the LAN is dead.
Summary: I bought this because I wanted mirrored disk and a time capsule. Compared to Apples offering this was slightly more expensive for 3TB but I was happy in the knowledge that data is mirrored and therefore protected against loss. Unlike some users here complaining about performance and set up, I AM an IT expert and have good knowledge of larger disk systems from IBM and EMC.
Great product (I think) but customer support is terrible

Summary: I was delighted when I first bought this (instructions are a bit rubbish and unhelpful but after managing to set this up it was great......for a week. I turned it off and when I turned it back on it told me that I had a degraded disk. Tried to contact customer support to help me resolve this. Can't find a telephone number so had to email. A week later I get a reply asking for more info.
Summary: This is more of a warning than a review, for reviews I would suggest looking at the DS212j on Amazon without any HDDs installed. I decided to buy the DS212j/6Tb rather than buy HDDs separately, even though it worked out slightly more expensive to do so, as I believed the HDDs would be those most suitable for use in this device. As always my order was seamless and it arrived the very next day.
Summary: Fruktansvärt seg maskin. Den lagrar ens filer men att använda den till något annat är inte lönt. Extremt långsam beroende på att CPUn belastas konstant. Uppdateringar av DSM har gjort det värre med tiden, den blir bara sämre och sämre, tyvärr kan man inte rulla tillbaka till tidigare versioner.
Summary: Nach 4 Stunden vergeblicher Bemühungen beim Einrichten gebe ich jetzt auf. Kein Netzwerkzugriff, Sicherungen brechen ab und das Einrichtungsmenue ist eine Katastrophe. Nach den vielen guten Beurteilungen hab ich mir dieses Gerät angeschafft und muss fest stellen, das fast nichts funktioniert. Für den Privatanwender scheint es ja noch einiger maßen brauchbar zu sein, aber sobald man mehr will (Netzwerkeinrichtung, Sicherungsoption, Zugriff von außen usw.
