Synology DS1517+ overview

  • 1Description

The DiskStation DS1517+ 5-Bay NAS Enclosure from Synology is optimized for encryption and intensive tasks. It comes equipped with five 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 five 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 DS1517+, it can be paired with two DX517 expansion units.

The DS1517+ 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 2GB 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 1165 MB/s and features four USB 3.0 Type-A ports and two eSATA ports which allow it to be connected to your system. Internet connectivity is achieved via the included four Gigabit Ethernet ports, each of which features link aggregation and failover support, allowing your stored data to be shared with users throughout the network.

For those who require RAID support, the DS1517+ supports RAID 0, 1, 5, 6, and 10, as well Synology Hybrid RAID and Basic RAID, each of which offers performance, data redundancy, or a combination of both. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized. For system expansion, the RAM may be upgraded to 16GB using two 8GB modules, and a PCIe 2.0 x8 slot supports either a dual M.2 SSD adapter card or a 10GbE NIC.

The DiskStation DS1517+ operates on 100-240 VAC at 50/60 Hz and includes an accessory pack, an AC power cord, and two Ethernet cables. It is certified with Windows Server 2012 and Server 2012 R2, in addition to being WMware and Citrix-ready, and OpenStack-compatible.

    Synology DS1517+ reviews

    DiskStation DS1517+ 5-Bay NAS Enclosure is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from Exactly what I need. Great product, originally mistakingly bought 1515+ and turned out it was not patched for the famous Intel Atom 2*** flaw. Able to return and get this one. Turn out the addition well worth the 200$ extra put in to it. As I have a third party PCI ssd drive (old OCZ, and my pc cannot boot from it), managed to plug it in, and the DSM recognized it instantly, so right now I have 16Gig memory and a PCI SSI drive as cache. As I don't use it for codec, so I don't really care about other people's complain. But I have installed virtual machine manager and hosting two instance of virtual machines in it, one windows 7, and one Ubuntu 16.04. So have been using it for 2 months, zero complain.

    Rated 5 out of 5 by from Amazing! I went from a Drobo FS to this. The Drobo was ok for backups but I only was getting about 15MBps when copying files to it. This unit gets a constant 115MBps when copying files. And the apps make it so much more powerful. I can also edit my videos from the DiskStation because of the much faster throughput. I upgraded to 16 gigs of ram. Not sure I really needed to since I only use the unit for data storage. Also installed the M.2 adapter board for Cache That does help for speed.

    Rated 5 out of 5 by from NAS System (DS1517+) for your video and photo files For years I have been confronting a problem how to store numerous video and photo files with nearly instant access. Tried different approaches, but most provided limited accessibility or long term safe storage of data.� Dedicated NAS with a hot standby drive was ultimately my solution. Configuration: I run 4x 6GB (WD RED) with a hot standby drive for redundancy (4 + 1).� System provides 15.7T of SHR storage which is at this time is adequate for my needs. In addition, I have upgraded MB to 8G RAM and a pair of Samsung 850EVO SSD cache drives. AC power feed to the DS1517+ is back-up with a dedicated Cyberpower PR1500LCD UPS to prevent AC line related anomalies. Operational experience: Setup was straight forward. It did take a while to initialize and commission drives. However, process was seamless and required minimum operator interaction.� Manual was clear enough how to install optional hardware. Finding out RAM information took some online research. Access from 1GB network is virtually seamless, however I've configured my system to hibernate if there is no access after 30 minutes. It takes couple of seconds for NAS to wake up and bring drives online. Not a huge issue, but one has to be aware of it. Fan noise is relatively low, but it is audible in a quiet room. Perhaps I'll upgrade to quieter units in the future. Software: Ahhh - yes. It works, but I have not used it extensively since I use DS1517+ as a dedicated NAS. I do not do any streaming from it or use it as web server, etc. Hence, I can not really comment on it.� So far system has gone through couple updates and seems to be solid. No complaints at this time.� NAS is operational� 21-1/2 hours a day and goes to sleep from 2:30am until 6am - is it bad or not to put system to sleep I simply do not know. So far my drive health (2 month) has been excellent. We'll have to revisit in couple of years. So far this has been positive operational experience.

    Rated 5 out of 5 by from DS1517+ Well integrated product The Synology DS1517+ is a very full featured NAS with a very well integrated disk management system. It offers high level storage performance and rich feature set to allow options for remote access, media services and integrated security. My initial set up using 3 terabyte WD NAS drives went smoothly though it took several hours to configure drives for Synology Hybrid Raid mapping.
    Date published: 2018-07-10
    Rated 5 out of 5 by from Works as advertised This is an easy to use system with a large amount of tutorials available online from both the manufacturer and current owners and users.� The system has a large library of apps and is very intuitive.� It is fairly quiet compared to my on desk Data array.� A must have for backup and redundancy.
