Synology DS720+ vs DS220+ NAS – Which Should You Buy?

Comparing the Synology DS720+ vs the DS220+ NAS Drive

Synology is still regarded as one of the most popular brands in the world of network-attached storage (NAS), with a clearly defined portfolio that accommodates home and business user needs accordingly, as well as all supporting the award-winning and remarkably easy to use Diskstation Manager (DSM) software. Despite this, many users still are on the fence about choosing the right solution for their storage needs. They have decided on a Synology NAS drive, but as each system has it’s own hardware highlights and the extent to which you can use DSM, it can sometimes be easier said than done to choose the right NAS server for you. Despite the wide variety of solutions available to NAS buyers in desktop/tower form, those who are making their first purchase in a NAS solution will generally consider a 2-Bay solution. It is compact, lower overall cost and (in 2020/2021 certainly) the growth of larger Hard drives and SSD (18-20TB right now) means that even a 2-bay NAS can support quite a large amount of data capacity (even in RAID 1). Also thanks to this, it means that the general hardware in a NAS outside of the storage (so, the CPU, the Memory, Connections and more) have had to be improved in order to meet these storage highs. Synology has several 2 Drive NAS solutions in their portfolio, that span numerous sub-ranges (Plus, Play, J, Standard and NVR) but today I want to focus on the DS220+ and DS720+ 2-Bay NAS drives, as these are very popular with home and Prosumer (professional consumer) solutions and both provide a very similar architecture at a glance, but to a differing degree and arrive at around $100-120 different in price. So, let’s take a look at both to see how they compare and which one deserves your data.

What can Both of the Synology DS720+ and DS220+ NAS Do?

It is worth highlighting that although these two NAS systems are being compared, each hoping for your data, they are both pretty good NAS drives in their own right. Of course, if you are going to go to the trouble of spending hundreds of pounds on a good network storage solution, whether as an alternative to cloud services like DropBox and Google Drive, or as a means of streaming all of your media, then chances are that you want to be doubling sure that it is going to be able to perform the tasks you need. I am pleased to confirm that regardless of whether you buy the Synology DS220+ or DS720+ NAS, it will arrive with and/or support:

  • Both units feature the Intel Celeron J4000 processors for a good price vs hardware balance
  • Both the DS720+ and DS220+ are constructed of plastic desktop compact chassis, thereby reducing power consumption, noise and heat generated
  • Both can Stream and Transcode on the fly (so, live) 1080p HD or 4K media, with superior performance natively and mid-range performance in Plex
  • Both the Synology DS720++ and DS220+ NAS support AI-supported photo and ‘thing’ recognition supported to a very high degree from the free branded software included
  • For Business users who currently enjoy the use of G Suite or Office 365, both of these NAS provide excellent means to backup your mass cloud accounts (as well as natively sync, dupe and configure rules on the fly)
  • Both the DS220+ NAS and DS720+ NAS support snapshots, for more incremental and version protecting failsafe in efforts to protect you from Malware and Ransomware attacks, by allowing multi-versioning storage history to browse through and restore

  • Both units are DLNA certified so can be accessed, browsed and played from by popular DLNA devices, such as Amazon Firestick, Alexa, Google Home Chromecast, Apple TV, Bose, Sonos, iPads, etc, as well as connectivity between these platforms with IFTTT
  • Both are multi-bay, RAID enabled devices NAS devices that support JBOD, RAID 0 and RAID 1 (as well as Synology Hybrid RAID too for their Plus series range), as well as supporting the very latest SATA based 16TB and 18TB NAS Hard Drives from brands like WD Red, Seagate Ironwolf, Western Digital UltraStar and Seagate EXOs media. Though it is worth highlighting the DS720+ is the only one that supports an expansion and therefore also can support RAID 5, RAID 6, RAID 10 and SHR-2
  • Both devices run on their own proprietary operating system that can be accessed remotely or locally. These include regular updates to the firmware, security patches, applications and more. Ranging from multimedia, home and multi-tiered backup applications, to more business end tools such as Surveillance software, Virtual Machine deployment and business-class backup and synchronization tools.
  • Both the DS220+ and DS720+ use and can be accessed equally by a multitude of mobile applications such as DS File, DS Video, Moments, DS Photo, DSCam and DS Music that are created by and constantly improved by Synology.
  • Both NAS are completely compatible with Windows, Android and Mac systems, as well as acting as a bring between software platforms to share and distribute files for migration and file sync (with improvements in newer DSM 7.0 later in 2020 to Mac Finder file streaming and file pinning
  • Both units can be used as a mail and/or business servers, providing excellent 3rd party CRM and first-party CMS systems, as well as the fantastic Synology collaboration Suite of applications Chat, Drive, Mail, Calendar, Office and Active Backup Suite
  • Both systems will support DSM 7 at launch and currently arrive with DSM 6.2 as standard
  • Both systems support the Synology Surveillance Station applications, support numerous cameras and arrive with 2 camera licenses with your purchase

So, regardless of whether you buy the DS220+ or DS720+ NAS, you are going to have a remarkably functional NAS drive. But, let’s dig a little deeper into the differences between these two devices.

Synology DS720+ vs the DS220+ NAS – Design

Both of these solutions are somewhat dripping in Synology Design in their external look, from the logo featured on the sides of each that doubles up as a passive airflow vent, to the click-n-load HDD bays that allow installation of SATA hard drives without a screwdriver and/or SSD (not too less). Both are tremendously compact and the bulk of the space taken is just for the media drives. The DS220+ external design is one that was first revealed in late 2017 (in the DS218+) that has two non-lockable storage bays that slide into the main SATA connected PCB inside. The front panel is removable and allows you to cover the bays, whilst still maintaining a degree of airflow, see the system LEDs (which denote system activity) and access to the front-mounted USB port and a one-touch copy button. Although both systems feature a front-mounted USB for localized/ah-hoc backups of the NAS system to USB 3.2 Gen 1 Storage (or visaversa), the DS220+ is the only one that features a physical button that allows you to action it physically – both systems can have the backup run in either direction automatically with a connected storage drive, as well as action via the system software on DSM, but many users (myself included) who use a lot of portable storage prefer the peace of mind of a physical action button option too.

Whereas the DS220+ Synology NAS has a rather relaxed/home user physical design in mind, the DS720+ seems a lot more ‘business’ and ‘stern’ in its design. It’s still a largely plastic design and is near identical in size to the DS220+, but there are clear differences. The chassis is less rounded and more angular on the edges, the chassis is a fractional larger to accommodate the M.2 NVMe SSD caching bays it includes (will touch on this later) and there is a distinct and clear change of approach to the storage media bays. The DS220+ had non-lockable trays and a removable front panel, whereas the DS720+ has two clear, key lockable trays that are uncovered. Both systems support hot-swapping and the SHR configuration, but the DS720+ just seems more business designed to use this feature in a real-world scenario really. The DS729+ also seems to have more ventilation on the front and base too, likely both because of the SSD caching bays and the likelihood that it will be working harder. The previous generation of expandable and Prosumer/SMB 2-Bay from Synology (the DS718+) arrived in a metal chassis, which many users particularly liked (you would need to weigh up increased heat dissipation benefits and robust nature vs noise and vibration of course) but the DS720+ has the same plastic material quality of the DS220+

Aside from these points above, the design of these is remarkably similar and, when looking at the rear cooling and port layout, near enough identical. I am inclined to prefer the DS720+ design, as although it lacks the USB Copy button that I much love, the DS720+ has those lockable trays, better passive cooling and better LED placement overall.

Synology DS720+ vs the DS220+ NAS – Hardware

As mentioned in my introduction, the hardware architecture of these two NAS drives are actually very similar on the face of it. Both of them are:

  • Intel Celeron CPUs
  • 2GB DDR4 2666Mhz Memory
  • 2 SATA Storage Bays
  • USB 3.2 Gen 1 Equipped
  • 2x 1Gbe LAN RJ45 Network Equipped

So, with that in mind, how are we able to choose between the DS220+ and DS720+ if the hardware is so similar? Well, the question here is a combination of VALUE and TOTAL Hardware Power.

Even a quick glance shows us that the Synolgoy DS720+ NAS hardware is either of a higher power, larger quantity or just has something available that the DS220+ does not. The difference (clearly highlighted in green) each tell you a way in which the DS720+ gives you more than the DS220+ – HOWEVER – It is worth remembering that both Synology NAS systems will provide very, very similar access and experience of the DSM software platform and GUI on day one to a single user. The Celeron inside each and 3GB DDR4 memory will keep things lovely and smooth and in terms of lite to mid-level access for a single user, you are not really going to find where exactly that $100-120 price increase on the DS720+ actually is! However, it is when you are planning on multi-user environments, multi-application environments, pushing the file types and file performance and, ultimately, if you plan on your network and storage environment growing rapidly over the next few years. The DS220+ is a very, very good NAS system and excellent for home and low-level NAS drive users, but there is the reason why it is lower in price than the DS720+ NAS. In brief, the price difference between the DS220+ and DS720+ NAS hardware can be summarized:

$100-120 extra spend gives you:

  1. 2x extra CPU cores, for handling bigger and more numerous tasks
  2. Expandability with eSATA to add 5 more Hard Drives with the Synology DX517 expansion system at a later date
  3. M.2 NVMe SSD Caching bays to add media that can leverage it’s faster access, lower latency and higher IOPS to benefit the slower but more affordable HDD RAID array
  4. 1 extra year hardware warranty from Synology

So, even though the Synology DS220+ is a very good NAS drive, if you can budget it (or expect to grow your use of the NAS system more over the years in terms of access, users, software, connected hardware and file types) I would recommend the DS720+ NAS in 2020/2021.

Synology DS720+ vs the DS220+ NAS – Performance

General performance between these two NAS is going to be similar through, right up until you start using it ALOT. Also, as mentioned in the hardware section, their respect differences in hardware architecture mean that for pretty much ANY task that is supported by BOTH the DS220+ and DS720+ NAS, the DS220+ is going to use more CPU and Memory % when doing it, as the DS720+ has that better-equipped CPU and SSD caching options. They BOTH have the 2GB memory which cannot official exceed 6GB (which users are less keen on) but a better CPU will always result in improved memory use and caching/flushing on the fly. The power use (in Watts) between them will be near enough identical in an average task (despite the slightly larger PSU Watt rating on the DS720+) as the system will only draw what it needs to run the Synology and 3rd party applications. The benefits of M,2 NVMe SSD caching on the DS720+ is an interesting subject, as it something that will only really benefit users who have a shared drive (access by many people needing the same files), small frequently accessed data that you access indirectly (thumbnails, processing data, background indexes, etc) and not really of use to LARGE file access. Also the NVMe SSD slots cannot be used for raw storage (unlike an SSD installed in the main storage media bays) which might put some users off in terms of the performance benefits long term on the DS720+.

There are other benefits to the Synology software platform of course. There are a whole bunch of backup options in Synology Hyper Backup and Synology Active Backup (supported on both the DS220+ and DS720+) that allow you to create a business class surveillance (NAS NVR) in your home or small office/business space. Though it is worth remembering that the DS720+ CPU will allow you to run more simultaneous cameras at a given time, despite their identical memory. Likewise, they both support Virtual Machines (with the Synology Virtua Machine Manager) software, however, despite both being a bit limited in VM deployment (that low memory again) the quad-core equipped DS720+ will do a much better job of Virtual Machine support in Windows 10 environments. Both systems will run the portfolio of Synology collaboration applications (File Station, Moments, Mail, Chat, Calendar, Office, Drive, Notes, etc) but the Synology DS720+ will support more directories, users, active syncs and simultaneously accessing users/programs than the DS220+ NAS. Even in terms of multimedia, they both (in their base setup) provide the same level of support, it is just simply the case that the DS720+ has more hardware under the hood, which translates into better software performance all round.

Of course, it needs to be addressed that a large % of people buying the Synology DS220+ or DS720+ NAS are doing so to enjoy multimedia, whether by using the first-party applications (Video Station, Music Station and Photo Station/Moment/Synology Photos) that are included with your NAS system, or popular 3rd party services such use as a Plex Media Server. In the case of first-party Synology applications, both systems perform remarkably well and close in a 1-person-access manner. This was to be expected, given that they both have an Intel Celeron processor with embedded graphics, so there is a component that is specifically designed in the architecture of that processor to handle graphic creation and handling (ie 4K and 1080p support in this case). Below is the performance of each in Synology Video Stations

Then there is Plex Media Server performance and how it handles the conversion of files on the fly (transcoding). Both systems perform well for their price tag, but the DS720+ just has more hardware available to it to get the job done and it cannot be overlooked. Below is how each of the NAS systems performed as a Plex Media server, playing and converting 720p, 1080p and 4K across a variety of formats.

Before we decide between these NAS based on multimedia, it is worth highlighting that the Plex Media Server application that is installed on the Synology NAS system (with regard to the Intel Celeron J4000 processors across all devices really) does NOT use the default drivers that the CPU needs to enable full access to the CPU transcoding engine and (certainly in the case of the testing above) affected the results at the time of recording. Since then, there has been a fix that vastly improves the performance of Plex Media Server on the Synology DS220+, DS720+, DS420+ and DS920+. You can read the guide on this HERE, or you can watch the video breakdown HERE. Aside from this, I think it is once again fair to say that in terms of performance, across all types, the DS720+ is still the better Synology NAS system overall for the money in this section.

Synology DS720+ vs the DS220+ NAS – Conclusion

It will come as absolutely no surprise that I recommend that between the Synology DS720+ and DS220+, I will almost completely recommend the Synology DS720+ NAS Drive. The DS220+ is still a solid, reliable and very user-friendly solution, which also benefits from a lower power use in comparison and more affordable price point (and that USB button I love so much!), but you are just getting so much more for your money in the DS720+ NAS and even if you need to make compromises in your choice of hard drive capacity in order to stay within your budget, you will not regret it. The Synology DS720+ NAS gets more done, get’s it done quicker and does it with more resources left over to do more afterwards – it’s a solid WIN from me.

In Summary, if you are looking to buy the DS220+ or DS220+ NAS;

 

Best NAS for Plex Media Server = Synology DS720+ NAS

Best NAS for Surveillance = Synology DS720+ NAS

Best NAS for Virtual Machines = Synology DS720+ NAS

Best NAS for Photographers = Synology DS720+ NAS

Best NAS for Business = Synology DS720+ NAS
