Final Thoughts




The Synology DS415+ as seen in our testing is a solid performing NAS appliance in all RAID configurations. This is largely due to its underlying Rangeley platform from Intel and also the NAS operating system (DSM). As with many NAS appliances, the heart and soul of a NAS is its OS, and thanks to many years of development, Synology has a winner with DSM. It carries some of the most crucial options for small businesses including free antivirus with the option to pay for McAfee if needed, along with AES 256-bit encryption and an optional two-step login process. As mentioned, at the heart of the DS415+ is the Intel Atom CE2538, which at this point in time is one of the strongest SoCs on the market for NAS platforms, and while it doesn't have the hardware transcoding capabilities of the DS415play, it can handle transcoding up to 720p. With that said, this platform is certainly not marketing towards home users, as it lacks an HDMI output.



Speaking more on DSM, the more time I have spent with it, the more I have grown to like it. More specifically, it is probably one of the most updated NAS platforms I have used, and by that I mean during my testing of this NAS that lasted a little over a week, three updates came through resulting in me having to retest multiple times to make sure it didn't affect performance. While this is an amazing feature in my book, it can certainly become annoying if you are updating your NAS so often. On the flip side of that, the update procedure is relatively quick and this NAS has one of the quickest boot up times I have ever seen. Package support seems to be gaining traction since my first encounter with a Synology product with Synology now having upwards of 50+ apps available, and while this certainly doesn't compare to what QNAP offers with their QTS platform, they do tend to offer everything a business would need.


Build quality of the DS415+ is rock solid, not that I would ever expect anything less from Synology but it's great to see them continue to deliver well built NAS products. Adding to this was our surprising find of the SAS backplane which could potentially enable business user the ability to use top tier drive solutions.


Performance of this NAS as we briefly mentioned above was stellar. I haven't seen a NAS solution this capable for quite sometime able to maximize our single gigabit connection in nearly every RAID mode. In single client testing, we saw some of the most impressive numbers from a RAID 0 with 115 MB/s and 113 MB/s in video playback, while RAID 10 touched 106 MB/s in video record. The same can be said with RAID 5 as it too was able to reach upwards of 115 MB/s in all video playback testing. With workloads, we of course saw the highest performance with RAID 0 coming in at 115 MB/s in seq. read, while random read and write topped 1500 IOPS.


Overall, the DS415+ is a solid performer top to bottom and with its current MSRP being listed at $599.99 in its diskless form, this unit is one the best units available in terms of price/performance.
