ASUSTOR provides their own ADM server software platform with all of their solutions and although it is not quite as advanced as offerings from most expensive NAS solutions in the market, it still arrives with a huge range of applications, services and is accessible via a web browser, mobile applications and desktop client tools. Their latest revision of this software is remarkably responsive and this alongside a number of their solutions also arriving with HDMI support means that you have a wide range of ways in which to access the data on your Asustor NAS in a tailored and appropriate way. The majority of their NAS solutions also arrive with BTRFS support too, as well as possibly the widest support in the market for 3rd party tools available in their application center. They are a little less polishing in the design of some of their tools compared with their biggest competitors Synology and QNAP, but they also provide a better value for money in their hardware with many solution such as the Locksterstor series featuring some genuinely game changing hardware for the price point. Here are some of the highlights of the ADM software catalogue:

Asustor ADM Video Review

In terms of these two brands, there is been a long-running theme all the way through that Synology has focused on FIRST-PARTY (i.e. Synology-brand) software and hardware priority, then supporting THIRD-PARTY services/hardware when they haven’t got a viable alternative in-house – to mixed degrees of popularity. Whereas QNAP has been a much more level playing field where they have released their own innovative hardware/software (occasionally a little too quickly) and singing its praises, but also tried to keep customization and flexibility for 3rd parties as open as possible and shouting loud-and-proud about that too – which can be a tad overwhelming for the less tech-savvy. Both brands have done an incredible job evolve their platforms as much as they have to date, especially when Microsoft, Google and Amazon are pouring BILLIONS into the SaaS (and PaaS and IaaS – Platform and Infrastructure as a Service) in order to create entirely streamable ecosystems for businesses, with NAS brands like Synology and QNAP not only integrating with them but also thriving alongside them as a local/bare-metal failsafe. These are all very lofty ideas and ones that most home or small business users will likely have little time for right now (aside from where NAS fits in with their Google/Office 365 office tools like documents, email and spreadsheets at a pinch) and for those users, who the NAS stands on its own two feet is what is going to matter most. Synology is earning its position in the market as the complete 1st party software and hardware package, with a genuinely groundbreaking range of available services, but still managing to make NAS accessible for all in DSM 6.2/7.0/7.1. That said, the trends we are seeing in those sub-enterprise services that are slowly receding in support of popular 3rd party hardware, software and services, making using a Synology NAS alongside your own existing setup in a frictionless way cannot be ignored and leading some to think Synology is shifting their industry position towards something higher.

QNAP NAS on the other hand, although maybe trying to cover too many bases at once, is still trying to cover as much as it can to appear to their audience. Their support of considerably more 3rd party platforms/software/services, even when they have their own software available, is certainly admirable and aside from rather aggressive pricing on their QVR Pro surveillance platform, are still the better choice for those who want a much more adaptable and customizable platform. Its a pretty understandable fact that most people who buy a NAS will be arriving with an existing collection of software in their daily workflow (Office 365 for docs, Gmail for their email, Plex for their media, Chromebook for their commute, Skype/Whatsapp for their communication, TB3 for their editing, etc) and it has to be said that QNAP keeps a more open platform to adapt a NAS into this mix than Synology – occasionally less intuitively and not without a little setup-friction, but certainly to more customizable results. Unsurprisingly, I am going to tell you that both Synology and QNAP NAS are good NAS brands and have earned their place at the top of the industry (whilst both making their own respective moves to integrate into the next tier – ie SaaS providers, Hyperscale environments and Boundless cloud storage), but there is no denying that no one brand has managed to do EVERYTHING to perfection. So, if in double, below is how I would recommend QNAP and Synology NAS to you, for each user case scenario and I hope this guide and my recommendations help you with your next big data storage purchase.
