This review is from: Synology DS916+ (8GB) Diskless System Network Storage
Pros: Operating System: Synology NAS are backed by the highest quality, most feature rich, and user friendly OS interface I have ever seen on a computing appliance. Even my oldest NAS - a DS110j from 2010 - still receives major OS upgrades and security patches.
Small compact size: fits nicely in the shielded corner of my desk. (I leave the unit with about two inches of air on all sides for cooling).
Synology Hybrid Raid automatic and flexible raid management.
I purchased this unit in May to replace an aging though still quite operational Synology DS212j. As a video enthusiast the option of 4K H.265 Video Transcoding as well as the ability to expand capacity by adding an additional five drive bays in the future via the DX513 finally sold me on it.
With my drives (WD Red 6TB NAS 5400RPM) the unit is quiet and hardly makes any noticeable noise.
Cons: A lot of plastic? (To be fair, this isn't all that different than the DS212j and DS110j I've owned, though the drive brackets in those were metal).
As the other reviewer mentioned, expanding a drive array migrated from another NAS will take an exceptionally long time. In my paranoia over protecting my existing 6TB mirrored array from my DS212j I purchased a third 6TB drive for the DS916+, copied the data to it, then expanded that array one drive at a time, finally purchasing a fourth 6TB drive to completely fill the unit. This process took advantage of a technology Synology calls SHR: "Synology Hybrid Raid".
The initial data copy of about 4.73TB ran overnight. Then the drive mirroring took most of a day, and adding the third drive ran a bit over a day. Expanding to include the final fourth drive took another 2-3 days.
I probably could have saved myself some significant amount of time by just taking the drives from my DS212j and plugging them straight into the new DS916+, then adding both new drives to the array in one shot. It probably still would have taken 3-4 days though.
There was some confusing documentation regarding migrating an array from one Synology NAS to another if the units are not the same model. As best as I could figure while taking an array from one model to another probably works just fine (if you make sure they're running on the same OS version first), it's not a supported practice. The idea that I could have gotten away with it anyway came from the fact that the new NAS seemed to have no problems recognizing that my old drives had a previously established SHR raid volume.
Other Thoughts: Product uses a plastic and screwless design. The front plate that hides the drives is held in place by rubber grommets and easily removed. The trays that hold the drives are also plastic, but seem to hold the drives securely. Drives are slotted in vertically, with slot 1 on the left ranging to slot 4 on the right.
All of my drives are WD Red 6TB NAS 5400RPM SATA 6.0Gb/s HDDs. Given the plastic and screwless architecture I can see how noise might be a factor with higher spindle speed drives.
Synology bills this as a workgroup/small-medium business NAS. Personally I think the inclusion of the Hardware Video Transcoding places it more in the high-end enthusiast market, but that doesn't mean it doesn't work for other markets as well.
Pros: Nice drive and decently fast while it lasted.
Cons: Purchased 5/13/2012
