Question: Does this come with data cables/connectors to attach the SATA drives? If I buy this and some bare-bones drives, will I be all set?
Document: Warning-  do not buy regular cheapo SATA drives,  this thing needs NAS quality SATA drives! Go to's synology.com and check the drive compatibility matrix before you buy SATA drives for this device. Raid-5 or SHR raid both allow you to recover from one drive failure out of four. Since this is a 4-drive box, expect around three drives worth of storage capability. One other note, it does not read Mac HFS drives!
We received the Synology DiskStation DS412+ about a week ago, and had purchased two Western Digital Caviar Green 3 TB SATA III drives for it. The drives installed easily, and the system is designed to pretty much set it self up. For some reason, we had problems getting the 412+ to recognize and properly install the WD drives. But after a couple of attempts, it finally installed everything perfectly.Aside from the glitches getting it up and running, now it is fantastic.
It instead offered a bunch of options about hardware configuration such as UPS integration, fan noise level, etc.In control panel, "DSM Settings" also was not helpful, although I did use it to set all connections to HTTPS.OK, weird. After setting all connections to HTTPS and using self-signed certificates, it did a web server restart and now the storage manager has come up on the web desktop.Maybe it was just a matter of time while the system checked the installed hard drives?
The feature set is extensive. Still very unhappy with the limitation of having to buy licences for cameras.03/27/2014 ***UPDATE***This is a solid buy with very good tech support. The problem i mentioned before with the volume failing to expand has persisted and additionally i started getting plagued with the DS locking up and  me having to restart it by turning it off and on every 45 days or so. This caused volume corruption but no loss of data.
Over the years I have owned so many different hard drives and nas systems, and frankly speaking this beats every single one of them hands down. It is fast, easy to set up, online tutorial available on synology website, web interface of your entire system, and runs silently in the background. I mean what else can you ask for?!? Trust me when I tell you this is a great system and I'll be more than happy to answer any questions that would convince you to buy one.
So far my husband and I love this Diskstation. My husband did the hard part and set it all up. He is familiar with all the server options as he works with them everyday. Easy to transfer data from our computers and our phones to this device. We bought pretty fast 3tb hard drives so information transfers quickly. Very happy with the size of the product. it will go to sleep and as soon as you open the app and hit transfer it wakes up as it should.
So speed was not the first priority. Second, I wanted to attempt to ensure some semblance of data protection. After reviewing and reading about all of the RAID types out there I have come to a single understanding. Nothing is guaranteed, and everyone has a different subjective opinion about the actual security of your data across the different RAID types. So in the end, make a backup, of your backup.
I'll be set for sometime, but I hope they continue to develop this, since if this ever fails, I would definitely buy another Synology Diskstation.
Pricy device but worth every penny, does not come with any hard drives, so be ready to spend more money for HDD, I recommend the NAS WD HDD.
This time, I performed large file copy tests to determine whether a consistent throughput could be obtained. Using 30GBs of data made up of several video files 3-8 GBs in size each, I tested throughput to the 412+ both via Ethernet and wireless connections. Ethernet transfers of these files averaged 60MBs via wired AFP and wired SMB connections. These results were obtained using an ASUS RT-N66U router, with both CAT 5E and CAT6 cables.
Answer: you plug the drives into trays so you don't need cables or connectors
