Description
DX517
 
Effortless capacity expansion for Synology DiskStation1  solutions on-the-fly.

5-bay 3.5”/2.5” SATA expansion
Easily add 5 additional drive bays to Synology DiskStation1. Supporting both 2.5” and 3.5” SATA drives, DX517 is a flexible solution supporting on-the-fly volume expansion or serving as a local backup destination.

Online volume expansion
Managed from DiskStation Manager on the host NAS, the additional bays in the DX517 are immediately ready to be used once connected. On-the-fly volume expansion ensures that storage and services on the host are not interrupted during volume expansion.

Hot-swappable drive tray design
The hot-swappable drive trays of DX517 allow easy drive installation and replacement without powering down the system. Screwless drive tray design reduces the time needed for system setup.

Dedicated local backup solution
Synology DX517 can be used as a dedicated local backup solution for the Synology DiskStation. When created as a separate volume, the DX517 provides a great backup solution to its local hard disks in case of system failure.

Synology NAS Expansion DX517 reviews


05/11/2020 | Guest | GB Flag |
What is the maximum storage DX517 NAS can handle?
It is better to ask SPAN for free compatibility checks. But as today you could fill it with 5X 18TB Seagate Ironwolf. This would give you a total raw storage of 90TB
04/11/2020 | Guest | GB Flag |
Can I use any drives with this NAS?
Yes, but we would recommend to use WD Red or Seagate Ironwolf. They consume less energy and generate less vibration and noise.
03/11/2020 | Guest | GB Flag |
Can I add a 2TB HDD and a 2nd one later with RAID1?
Yes, you can migrate from Basic single disk to RAID 1
02/11/2020 | Guest | GB Flag |
Can I upgrade the RAM on this NAS?
Yes, it will work with Samsung, WD or Seagate SSD. In fact this will improve the internal speed and make apps run faster.
01/11/2020 | Guest | GB Flag |
Is this enclosure suitable for a SSD - such as Samsung EVO SATA III SSD
28/06/2017 | | GB Flag |
Does what it says. No problems.

  PROS
designUsing the same chassis design that has been found in the previous NAS units and and expansion (the DX513) this new 2017 Synology unit is identical in design to it's predecessor.
featuresLacking a discernible CPU and Memory, this device does not provide any other features than adding storage - it does not feature or function independently of a connected Synology DS1517+ or DS1817+ NAS.
performanceOnce again, as this is a brainless storage box, it only performs as well as the NAS it is connected to.
valueIf you want the option to expand your NAS storage, this serves as an excellent, if slightly large solution. Let's hope a DX217 NAS expansion is released by Synology in the near future.

  CONS
designIt may well look the same as a NAS, sound the same as a NAS and be the same scale as a NAS - but this is NOT A NAS! This expansion is designed for those that want to expand their existing storage. However you will need more space (physical) as well as it needing it's own power supply.
featuresIf you want this to improve your storage in ANY way other than more Gigabytes and Terabytes, you will be disappointed as it does not provide any performance improvements what-so-ever.
performanceIt will only function as an added storage volume or expanded RAID if you connect to a compatible device. So you cannot just use this device with any unit before 2017.
valueHard to justify the cost from the outset. If you plan on going big immediately, you would be better off going for an 8-Bay or larger
