About this deal

ECC Memory has appeared on lots of Synology NAS’ over the years (with pretty much ALL devices higher than ‘mid-high business having it as standard now), so it is great to see it here on this 2-bay diskstation model. In other good news, whereas the DS720+ had 2GB of memory that was soldered to the main controller board and could be upgraded to 6GB with 1 free slot, the Synology DS723+ has two slots available (one prepopulated with the initial module) and can be upgraded to a massive 32GB. This again is thanks to that R1600 CPU being used. Although Synology still maintains quite a tight compatibility/whitelist on supported memory modules (stating that you can/should ONLY use their own first-party modules), I cannot fault the choice of memory and its upgradability here! Although 2x SATA drive 10G performance on the DS723+ and it’s CPU+Memory combo cannot be confirmed right now, I CAN answer the question of how the R1600 CPU and pro-class hard drives will perform over 10GbE in a four drive combo. Previously here on the NASCompares, I was fortunate enough to run ATTO tests on the DS1522+ (same R1600 CPU, but 8GB Memory and more bays) with RAID 0 and RAID 5, over four WD Red Pro 22TB Hard Drives. Now, it is worth remembering that these are NOT your common, everyday SATA hard drives and are designed to be rugged, high-performance disks (7200RPM, 512MB Cache, 10x 2.2TB platters, etc) AND the DS1522+ was populated with four drives (twice the maximum bays of the DS723+). That said, the results in both a RAID 0 and RAID 5 setup and in particular file size tests, full saturation of read transfers of 1.15GB/s was achieved, with write performance peaking at around 800-900MB/s. Now, these ARE artificial tests (so, not really representative of everyday use), but are nevertheless very compelling results for the CPU inside the DS723+ being able (with sufficient media) to sufficiently saturate the E10G22-T1-mini upgrade. More domestic/smaller scale HDDs such as the WD Red Plus or Seagate Ironwolf drives in a 2-Bay configuration of the DS723+ would likely cap at around 400-50MB/s at most. I have always been a big fan of the Synology Diskstation chassis for it’s minimalistic, yet attractive and efficient design. The absence of a USB copy button still irks me a little and the largely plastic design is not going to be to everyone’s taste, but you cannot fault the amount of R&D that has gone into the construction here. Let’s discuss the ports and connectivity of the DS723+ NAS. 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 recently for Mac Finder file streaming and file pinning There is no avoiding that the CPU choice inside the Synology DS723+ NAS is going to split opinion the tiniest bit. Until now, this 2/7-bay expandable product family has been exclusively Intel-based and integrated graphics equipped (Celeron, with a brief dance with Pentiums in 2016) which all benefited from particularly good multimedia & graphical handling when it comes to server-side transcoding/conversions, especially with more complicated and dense media formats such as HEVC/H.265. This is why the DS720+ (and DS718+ and DS716+ predecessors) were so popular for use as a Plex Media Server, Synology Video Station, Surveillance Station and even Virtual Machine deployment. The new Synology DS723+ NAS on the other hand is the latest system that has jumped ship from Intel over to AMD, with the DS723+ being built on AMD architecture, with a Ryzen Embedded Dual Core R1600 processsor. Now, it is worth highlighting that the R1600 IS a very good CPU. It is the same processor that is in the DS1522+, which we demonstrated could saturate 10GbE in a RAID 5 (more on this later) and also the DS1522+ NAS performs well in Plex at 1080p and native (non transcoded/convereted) 4K too, so the switch by Synology from an Intel to this AMD is not without merit. Before we dig deeper though, let’s discuss the specifications that we know about the DS1522+ NAS, alongside educated guesses we can make that are based on the CPU, product family and Synology’s past with the diskstation series:

Synology has switched to AMD hardware in lieu of Intel, and I'm all for it. The Ryzen R1600 that powers the DS723+ is a dual-core model with four threads, with a base frequency of 2.60GHz and 3.10GHz boost. The best part about the switch is that there's significantly more power here than the Celeron J4125-powered DS720+ and DS920+, making the DS723+ a true powerhouse.

Moving away from the CPU, we CAN talk about one thing that is likely to arrive onboard the Synology DS723+ NAS – potential 10GbE support. Now, before we get too excited, it’s really important to highlight that this would be delivered via an OPTIONAL single 10G Copper (10GBASE-T) module. The DS723+ will almost certainly arrive with 1GbE network ports, which will definitely disappoint some users who were hoping that 2022/2023 would be when Synology finally adopts 2.5GbE – especially when 2.5GbE is available on the Synology Router, arriving on many ISP routers, value routers, switches and more. It is not totally out of the question that Synology will surprise us and integrate 2.5GbE into this system, but realistically, they have been pretty clear about how little interest they have in it and I think they would see optional 10G on the DS723+ as a far more palatable choice – even on a comparatively bandwidth light 2x SATA bay system like this. 2.5G is now more than a fad in 2022. As greater than gigabit internet connectivity is becoming increasingly common (even ‘affordable’), so the thought that a NAS has the potential to be capped at 1GbE (109MB/s) when a particularly well-connected internet cloud service could exceed that is pretty disheartening. Still, the option of 10GbE would be very welcome, though in this case. some might wonder why they didn’t just roll this in and increase the DS723+ NAS price a fraction. The external connectivity of the Synology DS723+ and DS720+ NAS are, at least on day 1, near enough IDENTICAL! Both arrive with two-gigabit ethernet connections (a little disappointing in 2022/2023, but lets move on), two USB 3.2 Gen 1 (5Gb/s) ports for storage and supported accessories and an eSATA port that is used for attaching the official Synology DX517 expansion chassis (mentioned earlier). Now, after that, we can discuss the big, BIG difference between the DS723+ and DS92+ NAS: How do the Synology DS720+ and DS723+ NAS Compare in their Ports and Connections? NAS Model I’ve been using Synology NAS for 11 years on a 1Gb/sec wired network and am a Plex user. I’ve experimented with various setups to maximize 4K video delivery to various output sizes, as in iPad/iPhone, PC/Mac, 4K smart TV and 1080p projector. Any time a 4K video had to be transcoded to another size, the Synology CPU was buried. By one user. I found out that the Apple TV 4K also performs transcoding of 4K input to match the display it’s connected to. So the server no longer needs to perform the transcoding (unless I’m on my iPhone/iPad, which requires transcoding, and it isn’t pretty)! This means that the Synology NAS needs less processor cores/speed (in most cases) when transmitting video media. However, the extent to which you can use all these applications at any single time (both as multiple clients using the same software or multiple applications running in parallel on the same NAS system) is going to be better on the Synology DS723+ in the grand scheme of things, thanks to that potential 32GB of memory available to scale up down the line. Here is how these two Synology NAS drives compare in volume and features in those 1st party services: Both units feature x86 64bt processors (from AMD and Intel) to provide a good price vs hardware balance

These NVMe M.2 SSD slots are capped at 2GB/s (Gen3 x1) per slot. This is why IOPS are more important then SSD speed when you look for upgrades. the number of connections that can be maintained when the recommended number of hosted files was reached)Performance on these bays will comfortably saturate an external 10GbE connection (see gif below using two M.2 NVMes below tested with AJA externally over 10GbE). This is going to be useful for those that were concerned that 2x SATA HDDs or SSDs would struggle to saturate the 1,000MB/s bandwidth offered by the 10G upgrade. However, the full bandwidth afforded by the use of these bays in a storage pool is a little less clear than many would like. Both can Stream 720p, 1080p and/or 4K media, with superior performance natively and mid-range performance in Plex
