* It just works, seriously, pop in some drives, follow the web-based setup, and you're up and running.
* Synology Hybrid Raid makes things really flexible, you can mix and match drives and it will give you the most storage possible.
* Lots of applications that can be used on it, including Docker, which is super powerful, I even run a GUI-based linux using Docker so I can run an old legacy app I wrote.
* CPU is fine for normal NAS tasks and basic file extractions and such, however, the unit is supposed to be capable of running 'multiple virtual machines', but it's so slow it's almost impossible to run even a single VM on the CPU. Luckily I'm not super reliant on this feature.
* Fans are smaller, and therefore louder than my old 1813+. Not that they are super loud, but when you're within 2 metres of the unit, they are definitely audible.
In short, yes, I'd recommend this product, just make sure you run it through a high-end surge protector if you decide to get one, the power supplies are quite sensitive to surges and it's a pain getting a replacement power supply.
I have work for large companies for some time. As I studied Computer Science 30 years ago and have been working as Systems and Network Administrator for more than 20 years, always in companies devoted to developing software, I am quite used to software development and also to networks, NAS, SAN, etc. (I manage EMC ClarIIon, DELL Compellent, CISCO switches, servers, WMware environments, etc.)
I bought this last unit in order to implement Active Backup for Business for a really small environment, were just a few servers and workstations would be protected.
After installing the unit and configuring Active Backup for Business, it started failing randomly every day. Every single day there are backup tasks that are not performed because they are stuck waiting for other tasks to complete. A lot of tasks are issuing an “Internal unknown error” message, and suggestions to “Contact our Technical Support Team”.
I contacted Synology Support Team, and after almost a week of back and forth with different representatives, I have no applicable solution or workaround to this problem.
Now I have a bunch of servers and computers totally unprotected, and backups that could be useless because after so many failures I have no confidence on the integrity of the data backed up.
Until today my perception of Synology was really good. I had a couple of issues in the past with iSCSI targets used to connect to a VMware environment, but as it was for a development environment, I didn’t care much about it.
But today my perception of Synology has changed radically. I have a real and serious issue, I have data at risk, and Synology answers are evading their real issues and trying to put more weight on my end as a customer. That is totally unacceptable.
They say that there is an issue with the deduplication algorithm, but they haven’t offered any workaround (not even at a low level) to disable deduplication until they come with a solution.
If a job fails, it will trigger a chain reaction of failures that will affect other future jobs, even if it is a task for deleting the data that is going to be purged due to retention policies. After that everything starts to fail constantly. Their solution for that was to stop and restart the Active Backup for Business application, and wait for the next release of the application, probably in January 2019. That is also unacceptable. They also have issues with Hard Drives that are not aligned to 4K. But it amazes me that it is a random issue, because it works sometimes.
Synology is a great concept, and Active Backup for Business is also a tremendous concept, but their implementation is a real and total disaster, and support after failures due to their issues is beyond human imagination.
I am really sorry, but Synology has disappointed me to the point of no return. If you need a solution for backing up more than one computer (either server or workstation, physical or virtual) keep away from Active Backup for Business. I don’t really know if they will ever come up with a solution.
I'm only going to talk about transfer speeds which is what you may want to compare when choosing between different Synology models.
I purchased the DS1618+ to upgrade from my old and slow DS411. Anything I wanted to do with the DS411 spiked CPU usage to 99%, even simple file transfers (4 disk SHR-1 configuration), which topped at about 12MB/s.
Opening and closing apps was also terribly slow.
On the DS1618+ I used 3 older drives (16000 to 36000 hours) from the DS411 plus 2 new drives, all Western Digital RED 4TB in a 5x 4TB SHR-2 configuration and a single Volume (12000GB total usable space) for added HDD failure robustness, since I've had 2 drives fail within 1 month on the DS411 a few years back and was barely able to finish rebuilding after the first drive failed when the second one (different make and model) failed too. Plus RAID only helps you so far, only against HDD total failure, not with corruption or bitrot.
I was weary of the transfer speeds I would be able to achieve in this 5xHDD SHR-2 configuration (double parity means more CPU usage), since when I moved from my 2-bay DS211 with 2 HDD in SHR-1 to my 4-bay DS411 with 4 HDD in SHR-1, transfer speeds dropped from about 36MB/s to about 12MB/s due to the higher CPU usage. Lately this has been a pain since now I'm processing large amounts of drone images stored on my NAS.
But I was blown away: Transfer speeds are as fast as Gigabit ethernet allows you to. I never thought I would see 99% usage of my GbE PC connection. Both writing and reading from the NAS to my Windows 7 x64 PC SSD is about 100MB/s which I tested with a single 16.6GB movie file.
Since I had one drive slot left (Disk 6), I used it to put an older 64TB SSD I had laying around and enabled it as SSD cache. No need to buy the expansion card. However when using only one SATA SSD, cache is limited to read operations. But as you can see from the attached image, the sustained writing speed of 110MB/s was entirely done on the 4TB HDD. CPU usage stayed fixed at 30% during the entire transfer. (The difference between individual disk write speed is just because it shows the instant write speed, not the mean write speed which usually was the same between Disks 1 to 5).
Now I'm considering adding a second GbE port to my PC, since this NAS has 4 GbE port which support link aggregation.
I'm extremely pleased with this purchase. Plus it has INTERNAL power transformer, so there is no extra bulky external brick whose power cable comes out easily when reaching behind the NAS as the older models I have.
The only thing I wish my DS1618 has is built-in is 10Gbit Ethernet.
I think it's time for Synology to push the performance envelope and lead the SMB/home NAS segment into higher speeds with standard 10Gbit ports.
- High storage capacity with ability to expand the storage pool without taking the array down.
- The disk management software is extremely easy to learn yet powerful
- I/O performance is great and can be even better with the 10gbe expansion card. I consistently get around 114 MB/s transfer speeds over gigabit ethernet which I know isnt the fastest speeds possible but it is sufficient for me.
- Running a single 1080p Plex stream barely ticks the cpu/ram which leads me to believe this NAS could easily run quite a few streams at one time.
Side note: I used Carbonite to keep my Drobo backed up to cloud however the only plan Carbonite has that supports NAS is their business plan which is double the price of the home plan and only supports a storage size of 250gb (vs unlimited). After a lot of frustrating research I went with Backblaze B2 to back the synology up to cloud and while its not finished, it has been working fine. In addition, B2 runs directly on the NAS so it doesnt need to be linked to a host to run.
