QNAP vs. Synology vs. Asustor

threeMeet the possible predecessors of the future home computer. None are ready for that title yet, but, as technology evolves, the future will regard this design as a direct ancestor. These are more than network disk drives. They’re application servers that support massive disk capacities. They run 24/7 and require an almost insignificant amount of electricity. Linux transparently controls the show. In terms of difficulty, they require only a little more effort to master than the advanced functions on a microwave oven, although some of the applications might force you to Google something new in order to learn how to use them. Your browser is your terminal.

Technologically, these devices will take over when:

  • High rate megabit broadband speeds are universal
  • i5 / i7 or better class processors with ARM or less power requirements are commonly available
  • High capacity SSD drives in the terabyte range are inexpensive

But now, today, these are still mighty useful devices.

Three manufacturers dominate the smart network drive market. There’s no way to say one is better than the others. It’s a competitive market and, if one has cornered a niche, the others will move in shortly, or so it appears. I happened to purchase a QNAP TS-120 because I wanted certain features in a one drive configuration. Had I waited a few months, another manufacturer might have offered a better model, or not.

At this time, Synology is the most well known if you only look at mass marketers for information. QNAP is regarded just as highly but is a little less well known. Asustor is the newest kid on the block.

Each has a demo site that gives you hands on experience with their operating system.

Update: April, 2017: All of the Above vs. An Off-Lease Used Laptop

I wrote this page in late 2013. Most of the above is still current information although the apps and screens may have changed a bit. One option available today that was not available in 2013 is purchasing a used off lease laptop with a 3rd generation (or better) Intel processor and using that as a file server – media server – application server – and more. There are large numbers of used laptops available in excellent condition from  Dell, HP and others. They include i5 and i7 processors. eBay and Amazon are both excellent sources. If you shop well, one can be found in excellent condition for $150 and around $300 if you cherry pick. In some cases, you would want to upgrade the RAM to 8GB or 16GB and possibly install a new SSD, raising the cost by perhaps another $150. An upgrade AC class wi-fi card could add another $25. Some used laptops have specs that match those I just mentioned as recommended upgrades and still cost less than $300. When new, many of these laptops would have cost well over $1000. They’re solid and compare favorably to those being manufactured today. Make sure your selection has a gigabit LAN port. Many laptops sold today do not. USB 3.0 was common by the time these laptops were new.

I’m using a Dell E6230 with a 256GB SSD and 12GB RAM as a media server and it will also become a file server the day my QNAP TS-120 goes off to its reward. I paid $250 for A-Stock from Dell’s off-lease outlet (on sale) about a year ago. It has an Intel i5 3380M processor. Upgrades added a bit more cost. A spare USB 3.0 drive is also plugged in for extra storage capacity. Occasionally, it serves as a laptop with an external 60 inch 4K monitor since an HDMI cable runs from the laptop to the TV. A USB mouse / keyboard and an easy chair across the room add to the comfort. Not bad for relative pocket change. Windows 10 pro is full service for this purpose and anything I decide to do later.

Not long ago, I found a HP 2170p laptop with an i5 3320M processor, 8GB RAM and a 180GB SSD for $149 on eBay. An upgraded AC wi-fi card was added.  It’s a travel laptop due to its small 11.6 inch screen. I could just as easily make it the home server and carry around the Dell E6230 since it’s only a little larger.  HP commonly uses display port rather than HDMI, but display port to HDMI cables are both available and inexpensive from Amazon, eBay, and others.

Options like these were not available in 2013.

    Are they all linux variants?
    They do look very similar, and appear to have very similar apps available.
    Tried synology and was quite impressed, but I needed a non-headless server, e.g. using the server to output to TV via HDMI, plus the flexibility of windows to fit *any* hardware (tv tuners?) and know it will work and have drivers …

      I have specific experience only with QNAP and it looks like linux under the covers. Since each have similar apps and linux is almost everywhere, I suspect all are linux derivatives. I recall reading of NAS devices with HDMI out, apparently for the purpose of TV watching. Personally, I think a small PC would offer more flexibility at this time. Zotac, Intel, and probably others sell small PCs that are designed to be media boxes. You add memory, disk, and the O/S. Apple has the Mac Mini. I think that NAS boxes are evolving to eventually become similar devices, but a dedicated full featured media computer is also worth considering if media serving is your main application. Chromecast allows you to watch whatever is on your PC wirelessly. The only downside is you need a powerful processor if you are tabcasting from Chrome. I have acceptable results using a PC with an i3 processor having a Passmark score of about 3300. Higher would be better.

        Asustor’s have HDMI out. New reviews after your posts show that people are thrilled with that feature. I also saw they have a remote and USB dongle for the units. How sweet is that?

      • Carl Rinker says:

        The high end NAS market looks more and more competitive. If A has a great feature, B introduces a new feature and C figures out a way to one-up A and B. Then they do it all over again. I’m still waiting for the day when a company comes out with a utility computer that offers a powerful processor, comprehensive NAS features, and general purpose capabilities that multiple users can take advantage of. Basically a stripped down Windows-like Server on a NAS box. The home server with a minuscule power draw.

    I current use the Asustor AS7004T 4‑Bay NAS. The Intel Core i3 dual-core processor sold me on this model. The NAS was simple to setup for my family to access via the web via cell phone for uploading pictures. The surveillance app supports oem hikvision IP cameras. Also, the mobile apps, AiSecure, AiData are great.

    • Carl Rinker says:

      Sounds like a great system. Those are a lot like the specs I would look for if I replaced my little QNAP drive. It’s still adequate for storage and media server duties, but I would like to add virtual server duties to my network. The NAS is a good location. The i3 on your Asus should allow you to do just about anything you like for a long time.
