Question: Are the hard drives included?
Document: Looked long and hard for a replacement for my old Atom powered Windows Home Server. Synology's features just keep coming up on top. I've got a pair of WD Red drives in mine (mirrored). The feature set for the price is incredible and it really is extremely straight forward and easy to use.
We are a few months into using the DS214+ and we love it. We are a family of four that are heavy technology users. The Synology DS214+ was well packaged and very easy to set up. We started out with two 2TB WD RED hard drives (make sure you check for compatability before purchasing hard drives). The DS214+ was immediatly found by our home network and is availiable to all devices.
The DiskStation works fine now, but it was way harder than I expected to install it in my Ubuntu Linux 13.04 operating system. Fails to open in Browse Network, but after looking for solutions on the Web, I found out how to mount Diskstation files in my system. Typing code in Terminal.There was no problem finding the DiskStation on a virtual Windows Vista drive, in Network Neighborhood. There was no problem using 2-750 G hard drives from a defunct NAS.
I can't say enough how much I love this NAS. I should've purchased one of these long ago. The Synology DSM is very intuitive and fast. I just wish I would've known ahead of time that the DS214+ doesn't support Plex. That was one of the main reasons I purchased this and they're site does NOT clearly state that Marvel Armada processors, which are included on several of their new DiskStations, are not support by Plex. If you want Plex then go for the DS214 Play.
Great unit. Quiet, low power, hot-swappable drives, a quite-capable web-based GUI, but also SSH access to tweak what you want with the underlying Linux OS.
The NAS works well, transfers data at twice the speed of DS210j to/from encrypted folders. However, the fan never turns off. Even in low power mode with the drives in hibernate, the fan always runs. Unlike the DS210j in which was completely silent when in sleep mode.
We were completely satisfied with our Synology DS212+ so when we needed another 2-bay NAS, we did not hesitate to purchase the DS214+. It is FAST and silent with a pair of Samsung 840 EVO solid state drives.Synology is committed to continuously improving their operating system with updates that improve performance and features. Highly recommended.
The Synology NAS productline was recommended to me by a small business friend.I previously was using a Seagate Central as my NAS. But it had big and little glitches from the time I powered it up. Not so, for the DS214+.Setup was pure simplicity. Installation of the WD Red drives in the Synology NAS enclosure was effortless and required no tools.
Very pleased with this unit, I loaded it with two WD Red drives, initial build of the RAID array took several hours, but that's to be expected. File transfer performance is very fast, for example; 43Mb of pictures = done in under a second, 558Mb MS Office CD = done in 8 seconds - I found this to be a huge improvement over Netgear ReadyNAS devices I usually use, this will probably be my new favorite.
Reliable, fast, quiet, expandable. I've added 3TB to the internal network for storage of various files, and using the built-in packages, have put the photography folder on the internet for viewing of photo shots by customers. 1 click easy, literally, which is good because my Apache skills are a little raw. I am using just one of the two drives and there is a 5 bay expansion port when I need more allowing the addition of 20tb.
Answer: Hard drives were not included in the configuration that I purchased. However, you may (probably) be able order the Synology preconfigured with select drives.
