Synology DS1817+ overview

  • 1Description

The DiskStation DS1817+ 8-Bay NAS Enclosure from Synology is optimized for encryption and intensive tasks. It comes equipped with eight drive bays that are capable of natively supporting 3.5" and 2.5" SATA hard drives, as well as 2.5" SATA SSDs. Using its eight drive bays, this NAS will allow you to store and share a large number of files, including videos, music, photos, and documents with up to 2048 users. For those who wish to increase the overall capacity of their DS1817+, it can be paired with two DX517 expansion units.

The DS1817+ runs on Synology DiskStation Manager (DSM) OS, which is a browser-based operating system which helps to simplify managing your Synology NAS. Its CPU is an Intel Atom C2538 Quad-Core that runs at 2.4 GHz and its 8GB of DDR3 RAM allows frequently-used files and applications to be quickly accessed. The NAS is capable of achieving sequential read speeds of up to 1179 MB/s and features four USB 3.0 Type-A ports and two eSATA ports which allow it to be connected to your system.

    Synology DS1817+ reviews

    DiskStation DS1817+ 8-Bay NAS Enclosure is rated 3.3 out of 5 by 8.
    Rated 1 out of 5 by from Beware of failures! My DS1815+ went dead on me a few weeks ago. Only option Synology would discuss is "refurbished replacement." It finally arrived today. Scratches all over the unit. My original DS1815+ looked as fresh as the date it arrived in 2015 when I sent it to them. . The "replacement" has cosmetic and structural defects. Tried to install memory module but the cover must be bent as I could not re-close it. It is going back to Synology. Cannot get my data off the HDD installed in the unit. Terrible warranty service. Once you buy one of their products, they do not seem to care anymore and your data will be held in limbo. Beware!

    Rated 5 out of 5 by from I'm thrilled with this NAS The junky 4 drive WD Sharespace I had been waiting for to fail finally happened! Luckily the 1817+ had just arrived on the market. I purchased the bare unit with no drives and was hoping that my various WD drives would work in the unit... If not I'd purchase compatible drives. As it turns out the drive compatibility list is not an exclusionary list... none of my drives are listed on the known compatible drives, but they worked. I dropped in (2) 4TB Reds (4MB cache), (1) 1TB Black (8MB cache), and (5) 1TB Greens (4MB cache). I am fully aware that this is a mish-mash of drives that will affect performance of the unit and slow down parity checks to a crawl, but for my purposes and finances it was better to plan to add larger uniform model drives as the ones I installed fail (especially the Greens...). I'm not a network or computer professional and I found the setup of the device very straightforward. I had the Synology drive manager setup a hybrid RAID rather than specify myself so I can't speak as to the simplicity of managing your own RAID setup. Once the first 3 drives were installed creating volumes and folder access permissions etc was also very straightforward. I added the (5) Greens from the WD Sharespace after the initial setup of the first 3 drives... One was added to the first volume and the remaining 4 were assigned to a new volume. The parity check took several hours when I added the 1TB Green to the existing 3 drives, but this is a home device for me, not a business device with many users so the parity check was of no consequence to me... I am setting up to use the surveillance application, currently trying to figure out what cameras to buy, resolution, quality, etc... I haven't had a chance to try out the DLNA functionality yet... I will update review as I get more functionality tested, but I like the device very much. If you're just going to use it for file storage on the network, I know it'll likely do the job for you.

    Rated 5 out of 5 by from Performance extremely good for GE interfaces I use this as a backup to another 8 bay Synology NAS, and in initially setting this up, I connected to a switch using 2 separate GE pairs, each on a separate subnet. When copying from a raid 0 desktop over 10G switching to each port separately, I averaged 2.6GE throughput in write to raid 5 configuration. Did not test read speed but shold be fast. I would need 10G tests to see if I can get higher data rates, but works perfectly fine out of the box, no problems. Same good interface from vendor. Jim

    Rated 2 out of 5 by from Decent hardware + Poor Software + Poor Support = Terrible I would only suggest this product for experienced home users, who can live with some downtime. On the plus side, I have never lost data from a Synology NAS. That's the only plus I can think of. I gave this two stars instead of one, just because the quality of the hardware is actually pretty good. Synology just ruined it with the software and support.� If you need AD integration, DO NOT use this product. Yes, it has the ability to connect to AD, but in reality, the connection drops at least every two weeks, requiring reconfiguration. After the disconnect, no AD users will be able to authenticate to NAS services be it File Shares, Radius clients, or web/e-mail services. The RADIUS service is very immature permitting only USER access, and not supporting any form of device authentication, making it pretty useless.� Setting permissions on file shares/folders through the web interface is a bit tedious, unless you're happy with the basic read/write. If you need any form of custom permissions (i.e. write sub-files/folders only) you'll likely find it a pain.� SLOW... I have a Windows File Server and a large media share on an OS X server, (which we intended to migrate to the Synology), but just navigating the file structure on the Synology NAS proved so slow we could not move the data. It would take upwards of 30 seconds just to get the next level of folders to open. (Users would be spending 1-3 minutes just to get to a directory they needed a file from.) Now on to support... as mentioned in other reviews, the technical support is horrendous. It's purely e-mail based. Getting any type of phone support is extremely difficult, and is really no better. Every time I contact technical support for an issue (which is pretty much monthly for the past two years), I get scripted responses copied from KB articles I've already looked at online. (They don't have many helpful KB articles online either.) If more extensive troubleshooting is needed (anything a KB article won't fix, then the go to is they want unrestricted root level remote access to the NAS. Which means your NAS must have remote access from the internet and you're granting someone who knows as much as the KB articles tell them, root level access to your system, and all of your data. (I suppose I just don't trust people that much.) If you have or can use a Windows Server for file shares, I would highly recommend sticking with that option.� Bottom line, this is NOT a system suitable for most businesses, and in the end, even for home users it's probably going to be more of a headache than it's worth.� If you need a cheap solution/compact, buy a Mac Mini, plug in an external HDD enclosure that supports RAID, and use that as a share. Cost wise you'll likely come out about even, but you'll have a better product and much better support.� For those of you thinking of looking at QNAP now, I'll caution you there. The software on both is fundamentally the same, and the support from QNAP is even worse. (If that's possible) Also keep in mind, this thing is NOT CHEAP. You're going to pay nearly $1000 for a diskless system, then drop about 250 -400 per disk. That's $3000 on the low end. (+ if you need a memory upgrade, + if you need PCI expansion card, + if you need SSD or larger capacity HDD's)

    Rated 4 out of 5 by from Great product and value;-Some things don't work as advertise This is my first Synology NAS purchase for work. I have used a 2-bay unit at home for about 6 years now and love it. I bought this to create a target repository for my daily and archival server backups using VEEAM. The NAS is working in iScsi mode and is performing quite admirably. I highly recommend getting the 8 GB RAM version. This model also has a quad core CPU and it makes my personal 2 bay seem 20 years old in speed and performance comparison. My one issue with it is the option to add in a pci-e card holding up to 2 solid state M.2 drives to be used as dedicated high IOPS system cache. I purchased 2 of these N.2 drives from the compatible brand/model list and of course, the optional PCI-E card. Well the NAS could see the drives, but whenever I tried to create the cache pool the system would lock up and would require a hard boot to recover. I checked the user forums and contacted support but never got a resolution. So my advise to anyone looking for a quality Synology NAS is to ignore the cool option for dedicated cache drives and stick to the core features that make up a good unit. It still has the legendary Synology interface and is quick and reliable. It simply does not do everything it advertises. I probably could have save a few hundred and bought a model just as good, but without the cache drive option.

    Rated 5 out of 5 by from 3 systems later, Synology is clearly the best. I'm a video editor and I needed NAS storage for backing up huge projects that could be accessed by all computers on my network. (clarify-we always edit projects from USB 3.0 or Thunderbolt drives for the initial speed, and then store data on larger, slower, cheaper NAS drives like WD Red 5400rpm drives. But after that, if client needs corrections, we can actually edit directly from the NAS for client changes and revisions on 4K projects) Anyway, years ago, I started with Lenovo but found their interface quite complicated. I moved to WD EX4100 4-bays (I own four) and they CONSTANTLY need to be returned for warranty issues. Usually for fans that stop working and shipping costs I have to pay for. I then moved on to Drobo and liked the hardware, but found it slow. But then I gave Synology DS1817+ a shot and I can finally stop wasting money on other NAS systems! The DS1817+ interface is easy to understand. They have live phone and online chat support. The transfer speeds are FAST and the box is quiet!!! Sound was a huge consideration for me. Just one word of advice, when I bought my second unit, I went with the cheaper DS1817 unit to save $130. Wrong move. That extra $130 for faster processor and more RAM is extremely worth paying. Trust me on this one. So I returned it and got a second DS1817+ instead. Anyway, I've wasted a lot of time and money on other NAS, but the Synology DS1817+ finally gave me exactly what I needed. (I'm using one DS1817+ with 8 WD 8TB Red 5400 rpm drives and the second DS1817+ with 8 WD 6TB Red 5400 rpm drives. BlackMagic Speed test reflects speed of both of my Synology NAS units over a standard ethernet network)

    Rated 1 out of 5 by from horrible customer service This has to be probably the worst product you can buy as a NOT TECHNICAL CREATIVE... WHOS MAIN BUSINESS IS PRODUCTION AND NOT NETWORKING.� Synology does not care to help its customers over the phone, despite having a support number, the support staff are very laxidasical and only refer you to their support base articles online. Their turn around of tickets is a horrific 3-5 business days. Setting up the nas or any of its applications that you may want to use takes DAYS and if you having an issue what may seem basic enough that you should be able to use their support number to get a quick guided fix, IT TAKES DAYS...� Seriously, at this point, I think its such a bad buy that I would only recommend this to my enemies in the business. I DONT EVEN WANT TO IMAGINE WHAT WOULD HAPPEN IF YOUR DATA GET CORRUPTED AND YOU NEED A QUICK FIX TO SAVE A CLIENT.... THIS MACHINE AND ANYTHING ELSE FROM SYNOLOGY IS SCARY TO BUY AFTER HAVING IT FOR THE PAST YEAR.
