Mixed with the versatile Synology DSM working system, the DS1517+ has the potential to serve a variety of key roles on a community that transcend a traditional NAS. All this potential doesn’t come cheaply although, and that distinctive featureset may very simply discover itself underutilized. Nonetheless, if this arrange does fit your particular NAS wants, the DS1517+ is a worthy choice for extra demanding customers.

Who’s this for and will I purchase it?

No doubt, the Synology DS1517+ shall be overkill for lots of house customers. Slightly, it’s primarily aimed toward artistic professionals, and this NAS is versatile sufficient that it could fortunately help a variety of such creatives, starting from those that make money working from home places of work proper as much as small- or medium-sized companies. The featureset is sort of particular, and the important thing benefits aren't essentially easy to make the most of.

Synology DS1517+ value and availability

Launched globally April 2017, the Synology DS1517+ hasn’t been on cabinets lengthy sufficient to see a lot of a value discount. It’s additionally accessible in numerous specs, and add in playing cards (to not point out the onerous drives you’ll must make it work in any respect) are further. On the plus aspect, it's fairly simple to search out, with vast availability in shops throughout the US, UK and Australia. 

Within the US, the DS1517+ sells for round $685 for the 2GB mannequin, which will increase to $799 for the 8GB unit.

Within the UK, you’ll pay round £725 for the essential 2GB choice, which makes it a good bit pricier on this area, though the 8GB mannequin is a extra affordable £799.

In Australia, it’s not but attainable to search out the NAS for below AU$1,000, and the most cost effective 2GB RAM fashions price round AU$1,050. Leaping as much as the 8GB model places the value nearer to AU$1,200, which may be very price aggressive in comparison with including the RAM individually. 

PCIe growth slot

Whereas the DS1517+ has a PCIe slot, it doesn’t embody both a 10GbE community adaptor or M.2 SSD growth card. Whereas meaning you’ll be able to cut back your outlay by simply buying the one that you just want, as there’s just one PCIe slot, you’ll have to decide on both one or the opposite – you’ll be able to’t have each. Synology affords its personal branded community playing cards and SSD growth playing cards for the DS1517+, however the PCIe slot may also help quite a lot of third occasion choices. 

Synology’s 10GbE community playing cards are available in two flavours – the dual-port E10G17-F2 or the single-port E10G15-F1. The previous prices a hefty $268/£236/AU$450, whereas the latter is accessible for $155/£150/AU$220. Each use SFP+ cabling although, so would possibly require a community improve. Supported third occasion choices such because the Intel X540-T2 ($199/£204/AU$500) use RJ-45 Cat 6 cabling for a better improve path.

It’s extremely depending on the community setup, in addition to software, however Synology stories the NAS can present as much as 1179 MB/s studying, and 542 MB/s writing. That’s a large enhance in comparison with regular NAS learn and writes bottlenecked on a 1GbE community, and properly value the additional expense if you can also make use of it. 

SSD caching can enhance NAS efficiency for sure purposes, however even when it’s supported it is going to usually take up a slot within the NAS. Through the use of an growth card for this as a substitute, the Synology DS1517+ can maximise storage capability, whereas giving as much as a 2.7x enhance in I/O efficiency. The M2D17 growth card prices round $129/£153/AU$230, and handles two drives, that are further. One essential limitation to notice is that it helps SATA M.2 SSDs solely, not the quicker NVMe/AHCI PCIe fashions. 

Highly effective core specs

To make sure high-end efficiency (even with a number of customers), the DS1517+ contains some beefy for a NAS. The RAM is twin channel, but in addition upgradeable to 16GB. The Intel Atom C2538 quad-core CPU buzzes alongside at 2.4GHz, and has loads of spare grunt for operating your server fashion apps. The DS1517+ additionally has encryption in-built, to assist fulfill enterprise safety issues. 

The NAS can also be geared in the direction of expandability past the PCIe slot, with the power to deal with as much as 150TB of storage utilizing two DX517, 5 bay growth models ($489/£475/AU$750). You too can plug in different units and storage through the field’s 4 USB three.zero ports, or two eSATA connections.

Versatile software program

The Synology engineers have put in plenty of work into making their NAS working system (aka DiskStation Supervisor or DSM) extraordinarily simple to setup and use. Getting up and operating is so simple as slotting within the drives, connecting the unit to a community, and heading to search out.synology.com in an online browser. The DSM internet interface emulates a desktop computing surroundings, full with 'desktop' icons and applications that open in their very own home windows, which might be dragged round and rearranged as desired. Upon first login, DSM walks you thru the remainder of the (fast) setup, and features a information to getting began with the extra in-depth options.

The DS1517+ is able to operating an enormous number of apps, from backups and easy file sharing to video surveillance, virtualisation, and private cloud storage.

If you wish to carry out file operations — copying, shifting, organising and deleting — that may be finished instantly by your internet browser too, through a DSM app known as File Station, which works virtually identically to Home windows' File Explorer or Finder on Mac. It's very intuitive and saves you the trouble of mounting drives on a distant laptop if you simply need to rapidly tidy up or transfer a few recordsdata from one shared folder to a different.

Furthermore, because of help for the Docker platform, principally any Linux server software can be run in DSM inside a digital machine, supplying you with an enormous collection of third-party purposes, starting from internet servers to your individual Netflix-like film server or devoted downloaders for protocols like BitTorrent and usenet.

Efficiency and benchmark outcomes

We examined the DS1517+ with twin Seagate IronWolf Professional 10TB onerous drives, set to RAID 1. Our overview unit didn’t embody a PCIe community card or SSD growth slot, so it was examined over a daily 1GbE LAN. 

Due to the highly effective CPU and 8GB of RAM, the NAS had no downside saturating the community connection. We achieved sequential speeds of 111.four MB/s writing and 110.three MB/s studying. Testing out within the wild present that Synologies 10GbE efficiency metrics are very achievable. 

Anything I ought to know?

The Synology DS1517+ is a good NAS on the technical entrance, and may very well be an actual asset to a high-end private consumer, or a small or medium enterprise. That mentioned, getting essentially the most from the NAS isn’t essentially simple, or low-cost. For many customers, the 2GB RAM mannequin is value skipping as a result of it’ll be a bottleneck on the subject of what number of purposes you’ll be able to run. Until you intention to improve a 2GB mannequin to 8GB or 16GB your self, we’d simply go for the 8GB DS1517+ proper off the bat. 

Alternatively, it’d be simple to go properly past your wants and overspend on this NAS too. Shopping for the 8GB model with a 10GbE community card and a set of 5 6TB Seagate IronWolf drives will price you virtually $2,000/£2,500/AU$three,000, for instance, and except your community can deal with the excessive speeds, a few of the further efficiency and flexibility supplied by these upgrades shall be wasted. The identical goes for the PCIe SSD growth – it’s a terrific choice to have, however solely these with excessive enter/output workloads will be capable of achieve the total benefit.

The DS1517+ additionally faces competitors from Synology’s higher-end DS1817 ($850/£895/AU$1,350), which has eight bays and dual-port 10GbE networking in-built, though it lacks this mannequin’s PCIe slot, so it’s in the end not fairly as versatile. The DS1817 is provided with a slower CPU too, though for simply $50/£95/AU$150 greater than the DS1517+ (when evaluating costs on the 8GB RAM mannequin), it’s a compelling various if you wish to prioritise larger storage capability over horsepower and suppleness.

It prices across the identical value because the DS1517+, however this eight-bay NAS affords extra storage capability because of its further three drive bays. Plus, it has two built-in 10GbE ports (alongside one other two 1GbE ones), so in contrast to the unit reviewed above you don't must pay further to acquire higher-speed networking. The DS1517+ does supply a quicker Intel Atom processor, nonetheless, with the DS1817 utilizing a barely slower quad-core 1.7GHz ARM Cortex-A15 class processor, though the latter does make up for a few of that by together with 4GB of RAM out of the field.
