Network-attached storage vendors do not usually follow a regular yearly cadence in updating their offerings. Releases for different market segments are spread throughout the year. That said, thanks to the Consumer Electronics Show (CES) held in January, the first quarter of the calendar year provides glimpses into what vendors have in store for the foreseeable future. Some of the announced products are either available for shipment right away or get into the market later in the quarter. Today, we will take a look at the various options currently available in the commercial off-the-shelf (COTS) network-attached storage (NAS) market space.
The COTS NAS market can't be simply delineated based on price and performance. As a rule of thumb, one can say that the price of a NAS increases with the number of bays in it. However, even within the same number of bays, we get NAS units spanning a wide price range. Any consumer in the market for a NAS needs to consider the following aspects before deciding upon the budget:
- Amount of storage needed (number of bays)
- Intended use-case
- Business-oriented or home / multimedia-focused
- Expected number of simultaneous clients
- Downtime tolerance
- Required processing power (both file-serving and apps)
- Value of invested time (in the case where there is a toss-up between the COTS and DIY routes)
- Mobile and native NAS applications ecosystem
We have evaluated a large number of NAS units (with different bay-counts) over the last several years. The lineups mentioned below (in alphabetical order) are the ones that we are comfortable recommending for purchase after putting a few of their members through long-term testing. Compared to previous years, we have removed the LenovoEMC i- and p- series, as well as the Seagate NAS and NAS Pro units, as they no longer seem to be available for purchase and no new products have been announced in the last year (even though their support forums are still active with official replies).
- Asustor Storage Units
- Buffalo LinkStation and TeraStation Series
- Netgear ReadyNAS Series
- QNAP Turbo NAS Units
- Synology DiskStation and RackStation Series
- Western Digital Consumer Series
- ZyXEL Network Storage Units
In this guide, we present suitable options for 2-,4- and 8-bay NAS units targeting the home consumer / SOHO market. One important aspect here is that we are not going to talk about the high-end SMB market or the multitude of offerings that come with Windows Storage Server or some similar flavor. Only products based on custom OSes are being considered in this guide.
Option 1 (2-bay): Western Digital My Cloud EX 2 Ultra [ Diskless: $160, 2x2TB: $350 ]
Most units sold in the 2-bay market are purchased by the average consumer who wants to back up photos and videos taken with mobile devices. A performance powerhouse is rarely needed in this market segment. While the user experience with the mobile app(s) is vital, the presence of apps on the NAS itself is just an icing on the cake.
Western Digital revamped their 2-bay product line last month with the My Cloud EX2 Ultra. Compared to the previously recommended My Cloud Mirror Gen 2, this is a slightly more powerful offering with double the RAM (1GB DDR3). Models start at $160 for the diskless version and go up to $900 when bundled with two WD Red 8TB helium drives.
Western Digital has also been enhancing various core features such as backup and sync capabilities in the My Cloud OS. Integrated Docker capabilities in the My Cloud OS point to the possibility of multiple easily-integrated third-party apps in the future. Western Digital is obviously a big vendor with end-user support appropriate even for non-tech savvy folks. Coupled with the plug-and-play experience, this makes it an ideal purchase for anyone who is looking to get started with network attached storage and needs basic data protection.
Option 2 (2-bay): Synology DS216+ [ Diskless: $300 ]
Power users wanting to experiment with btrfs and needing a more full-featured COTS NAS OS need to look no further than Synology's DSM 6.0. btrfs is available only on x86-based NAS models. The most economical Synology NAS for users wanting to evaluate btrfs for their needs is the Synology DS216+, based on the Intel Braswell platform.
The DS216+ is not going to break any benchmark records, as it is held back by the single GbE LAN port. However, the capabilities of DSM 6.0 and the powerful x86 platform, as well as the pricing make the Synology DS216+ an interesting product to consider.
Option 3 (4-bay): ZyXEL NAS540 [ Diskless: $220 ]
The ZyXEL NAS540 came in for review last year, and is still under evaluation. But, we like the unit enough to be able to recommend it as an alternative to the popular LenovoEMC ix4-300d (now that LenovoEMC is no longer selling that model). The main attraction here is the price - $220 for four bays is approximately the same as what the ix4-300d used to cost when it was in the market. However, the NAS540 has double the RAM (1GB DDR3) of the ix4-300d. It also supports hot-swapping of the drives, unlike the ix4-300d.
The NAS540 is a PowerPC-based unit (Freescale/NXP FS1024 (M86203G12) C2K dual-core @ 1.2 GHz). It comes with dual GbE LAN ports, a USB 3.0 port as well as a SD card slot. ZyXEL has equipped the NAS with enough features (mobile apps, remote access etc.) to make it deliver very good value for money. Obviously, one shouldn't expect the finesse and capabilities of OSes from the likes of Synology and QNAP, but, again, the price more than makes up for the missing features and sporadic firmware updates.
A couple of days back, Synology announced the Marvell ARMADA 385-based DS416slim (with support exclusively for 2.5" drives). While it is definitely an interesting product (particularly for power users requiring a small, power-efficient storage box for home-based virtualization labs), the average storage-hungry consumer is better off with a traditional 4-bay unit.
Option 4 (4-bay): QNAP TS-453A [ Diskless / 4GB RAM: $599 ]
The first quarter of the year hasn't seen too many updates on the 4-bay front (particularly talking about x86-based models). QNAP did launch their Braswell-based units at CES. In our previous guide, we had recommended the QNAP TS-453 Pro. The Braswell version is a worthy update that we will continue to recommend for the same reasons. The TS-453A comes with four GbE LAN ports - ideal for dedicating to virtual machines running on the NAS.
We wouldn't suggest running intensive VMs on the Intel Celeron N3150-based TS-453 Pro, but the platform is powerful enough to run Ubuntu VMs and the like for, say, acting as a home automation controller. QNAP's QTS is very rich in features (both mobile apps and the NAS apps ecosystem), and is perfect for power users.
Option 5 (8-bay): QNAP TVS-871-i7-16G [ Diskless / 16GB RAM: $2199 ]
Our 8-bay recommendation is retained from our previous guide. The TVS-871-i7-16G is a no-holds barred NAS sporting a Core i7-4790S Haswell processor. With 16 GB of RAM and a minimum of 4x 1GbE ports (additional 2x 10G also possible with the spare PCIe expansion slot), this NAS is ideal for running multiple intensive VMs. The 4C/8T Core i7 CPU ensures that there is enough processing power for the VMs and plenty to spare for the NAS functionality as well as apps running on the NAS itself.
The TVS-x71 units are meant for the high-end SMB market, but, in our evaluation of a TVS-871T-i7-16G unit over the last several months (review is coming out soon), we can say that it is positively drool-worthy for the high-end power users with cash to burn. The Pentium-based model comes in at $1350, while the Core i3-based one is at $1377.
For a more moderately priced 8-bay system on the COTS side, one could opt for models such as the Synology DS1815+ [ $961 , Review ] or the QNAP TS-853A [ $999 ]. Obviously, going the DIY route with, say, an ASRock Rack C2750D4I board and a U-NAS NSC-800 chassis [ Review ] might make for an interesting build, but the price difference is not that big (approx. $845 vs. approx. $1000) when build time and software management aspects are considered.
Option 6 (4-bay): Netgear ReadyNAS RN214 [ Diskless: $500 ]
On the 4-bay side, Netgear's ReadyNAS RN214 with an updated quad-core Annapurna Labs SoC and btrfs support is an interesting option. Coupled with the newly introduced Netgear Nighthawk X8 R8500 tri-band 4x4 802.11ac router and the promise of plug-and-play link aggregation support, it presents a compelling solution for consumers in the market for a router as well as a NAS.

BurntMyBacon - Thursday, March 31, 2016 - link@jabber: "Yeah people really don't factor in the fact that you can have a NAS box arrive in the box and have it up and running 10 minutes later."
You realize you can do that with FreeNAS as well:
Granted, prices are high for home use, but these are stupidly overpowered (Core processors, ECC, 16GB RAM min, Link Aggregation, Cache drive support, etc.) for a home user. It only took me 3 minutes to find these.
@jabber: "Plus as others mention far less clutter. Tuck it away and forget about it. Plus if you install it in an office people are less likely to try to fiddle with it or try to use it for something else."
Neither the unit I build, or the mini I linked above have any more footprint than these NAS units. The rackmount unit has a larger footprint, but if you already have a rack with an open slot, it takes up no additional floor/desk space in your office. People aren't likely to fiddle with any of these, but they are less likely to mess with the rack than anything.
@jabber: "Then you don't have to touch it again for months if need be."
Years actually. Sure one of these NAS units may outlast a spare parts built FreeNAS system, but there is no reason to expect them to last any longer than a well built FreeNAS unit. In fact, if you use a proper enclosure and don't skimp on the cooling, your FreeNAS unit (or at least the HDDs in it) can and have lasted longer than some of the more poorly ventilated units presented here.
@jabber: "FreeNAS? You can keep it chap."
I will. Thanks. And my ZFS too. For 8 years now.
Been giving some thought into updating the OS to a version that supports the plugin system, but I can't seem to convince myself to fix it if it ain't broken.
aebiv - Friday, April 1, 2016 - linkThe 9.3 train has been pretty stable. I think we've got around 20 or so boxes in the wild, all humming along with no drama.
Visual - Friday, April 1, 2016 - linkSingle-bay NAS? What in the world for... How is that different than plugging a USB drive to your wifi router?
Shadow7037932 - Thursday, March 31, 2016 - linkThese are mainly aimed at SOHO and midsized businesses that don't have the IT people to do a custom build and/or want vendor support.
jabber - Thursday, March 31, 2016 - linkSpot on. That's why I roll them out to all the small business offices I support rather than FreeNAS boxes. Set and forget in the main. All they ever want is backups and file sharing. Never gets more technical than that.
BedfordTim - Saturday, April 2, 2016 - linkThe flaw in your argument is the vendor support issue. Our NAS from one of the winning manufacturers went down when the power supply failed. Had this been a PC we could have had it up and running the same day. Being a NAS you are limited to the vendor and a quick look at the Amazon reviews or their Facebook pages will tell you they are all pretty shoddy. It tool a whole week and an hour on a premium rate number to fix our two week old NAS.
jabber - Sunday, April 3, 2016 - linkNot been my experience. Rolled out over 20 in the past 7 years. All running like clockwork.
CalaverasGrande - Thursday, May 12, 2016 - linkSome folks have a lot of irons in the fire. I could easily put together a NAS form of the shelf parts. I've worked in IT, media production and software dev for years, so I have the skills. But I also haven't bothered to keep up to date on all the chips, drives and motherboards that are out there. I'm not sure which SFF cases are the best combination of features, form and reliability.
So I'd have a weekend of research ahead of me before I could plan out a NAS that I'd trust my data to. Or I could buy a purposebuilt unit and get on with my app development, animation, music and other projects.
OTOH I have made old Mac Pro's into NASes on several occasions. They have robust power and cooling, and can be retrofitted to increase the number of drive positions past 4. They can also run various versions of Linux if you are not happy with OS X.
milkod2001 - Thursday, March 31, 2016 - linkWould love to see direct comparison of best 2 and 4 bay units. Compare : Price / Performance - reads,writes, access times / Fan Performance -noise levels / Features / Software / RAID options / Durability / Disk Rebuild Times etc
Also how easy / difficult is to upgrade RAM. Is it even possible? Can i just open case and throw the same type but bigger capacity RAM into that?
DanNeely - Thursday, March 31, 2016 - linkAFAIK slotted ram only shows up on higher end models straddling the SOHO/SMB line. Without checking the specsheets, I'd say the QNAP is the only one likely to have that feature.
