An AMAZINGLY fast NAS

Reviewed in the United States 🇺🇸 on October 22, 2018

Verified Purchase

I'm not going to talk about the great Operating System in Synology NAS, it's the same in all Synology Consumer NAS. My older DS211j, DS211 and DS411 still get both security and OS updates at the same time. Two thumbs up for the continued support of older models, with the notable exception of not supporting btfrs in the DS411 which I now use for backup. WHY? All the necessary drivers are included in the respective DSM.

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.

if you need network attached storage, this one is great

i'm not especially technical when it comes to network attached storage. i hired someone on freelancer to log in remotely and help me set it up initially. then had a computer fail and needed to reinstall on a new unit. passwords for the nas were lost (in a file on the old computer). i searched Synology's support site, followed instructions, and reset passwords and loggin in to the box. All data is still there. Very happy after several years of use.

Great mid-range NAS for a resonable price

Reviewed in the United States 🇺🇸 on October 1, 2020

Verified Purchase

Not much to say here except this: if you need a 6-bay NAS at a reasonable price, this is about the only alternative. IMHO the newer versions (with the slightly improved CPUs) don't seem to hold an edge performance wise for the average home user/SOHO user.
RAM upgrade is easy assuming one gets the right type RAM. I ended up buying the Kingston HyperX 32GB kit direct from Kingston at a great price (25% lower than advertised elsewhere). Naturally, the Synology unit will display a warning that it detected non-Synology branded RAM, but this is a cosmetic issue.
My humble advice along the lines of upgrading the RAM: don't be skimpy and do not buy a bargain brand to save $20.
I also have an older Synology RS2416RP+ (12-bay) NAS so for me there was no learning curve as far as installing or configuring.
On side note: I read someone else's review where the user complained about the drive brackets being flimsy and rattling during normal use. While I won't say that Synology couldn't construct a more sturdy drive bracket the rattling noise is simply not true. In fact, with the 6 older Toshiba 4TB drives I installed I could very well have left the unit in my bedroom without ever noticing background noise, heat, etc.
The application suite that is part of the bargain when one buys the NAS itself is more than adequate for most users and there are numerous 3rd party options ('for pay') as well.
Overall, I would highly recommend this model (DS1618+).

Great NAS

Reviewed in the United States 🇺🇸 on May 12, 2020

Verified Purchase

After two QNAP NAS's I decided to try Synology, and I was not disappointed. It is not as glitzy as QNAP, but it can be argued that when it comes to functionality, QNAP has a lot more work to do to catch up. Everything that I had read about Synology turned out to be true, and to sum it all up, It Just Works. Its features are not necessarily the latest and greatest technology that sometimes works, and there is no real use case for them yet.

Instead, they are well thought out, well designed, and well-executed. It can servers a windows domain controller, as a VPN server, Media server, file server, you can carve LUNs and connect to machines that are low on disk space, transfer files back and forth in high speed (thanks to its team able four network ports), etc. The wealth of its application portfolio is impressive. The network back up sever not only works flawlessly but with its de-duping technology has shrunk my backups from 1.4 TBs every night to 200 GBs by efficiently removing repeated data between back up volumes of any machine. I could be sitting here and write for a long while about Synology NAS features. Instead, I think you are best served to investigate further for yourself.

Exceptional NAS. Some would argue for FreeNAS/unraid/other with ZFS, etc. Good option - stating that, this is my second Synology. My last one lasted me 7 years. 7 years! Flawless execution, and was supported until the day I replaced it. With 4 NICs and an expandable PCIe slot for 10gbps This device checked the boxes. For my use case (vsphere/ESXi) I needed exceptional, scalable storage with no hassle management. Synology makes an ultra consistent, high performance device in the 1618+.

Just awesome...

Reviewed in Australia 🇦🇺 on January 26, 2019

Verified Purchase

As always, Synology creates awesome products that just work. I purchased this unit as my primary unit, and I'm now using my older DS1813+ as my backup unit. It works really great with snapshot replication, so it now replicates all my data overnight, which is what I wanted. I'd want to write all about it's features and such, but we'd be here for a long time. So I'll just cover the main pros and cons:
PROS:
* 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.

CONS:
* 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.

Capable of Massive Storage

Reviewed in Canada 🇨🇦 on November 13, 2018

Verified Purchase

Had someone install and set-up this unit as I'm only intermediate at the techy stuff. Once it was set-up I am able to use it with no trouble at all. It comes with a lot of built in useful software some of which I use and some I don't use. It also lets you know the health of the unit and the temperature of each individual drive. It has never risen above the normal range yet and I have been using it for a couple of months now. I only turn it on when I am going to load something onto it or watch or listen to something I have put on it. I use it for backing up all my video and audio media and use it along with WD TV and am able to watch or listen to anything I own with a small remote. No more searching for a particular item...it is all right in a menu on my tv It is also nice that I don't have to handle the individual discs anymore possibly causing damage and wear.. This is a NAS unit so it can be used either as one large storage unit or as I use it a backup. If something should happen to one of the drives I have in it I just need to replace the drive and this unit will replicate the damaged drive therefore your data or my case media is protected. The SynologyDiskStation does everything I hoped it would and only time will tell of it's longevity and possibly of it's back-up capabilities.

Best NAS for prosumers that is easy to use.

Reviewed in Canada 🇨🇦 on August 3, 2020

Verified Purchase

Ok, first of all, if you’re a true enthusiast, you’re not buying this - you’re making your own with FreeNAS.... but if you just want something to work - and you still want customization - this is the way to go.

I added 6 16tb drives, 32gb of RAM and the 10Gbe add-on card... while not necessary, I REALLY recommend the RAM upgrade, as if you want to run any services (I run a PLEX server), you’ll need it while a backup is going on....

The 10Gbe card is obviously only necessary for those who require high speeds... and have a router/switch that supports it.
