Synology DX517

Features: 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.Specifications:Applied Models:- Supports creating volumes across different units: - 21 series:DS1821+, DS1621xs+, DS1621+, DVA3221- 20 series:DS1520+, DS920+, DS720+- 19 series:DS1819+, DS1019+- 18 series:DS1618+, DS918+, DS718+, NVR1218- 17 series:DS1817+, DS1817, DS1517+, DS1517- 16 series:DS916+, DS716+, DS716+II- 15 series:DS1815+, DS1515+, DS1515- Supports creating volumes on a single unit only: - 18 series:DS218+- 16 series:DS216+, DS216+II, NVR216- 15 series:DS415+Notes: - For more information on the compatibility of each expansion unit, please refer to this article.- Please upgrade to DSM 6.2.1-23824-5 or later version before using it with 15 and 16 series models (excluding DS1515, DS716+, and DS716+II).- To have better performance, we recommend creating storage volumes physically located within the same NAS or Expansion Unit, rather than creating volumes across your NAS and Expansion Unit.Storage:- Drive Bays: 5Compatible Drive Type* (See all supported drives): - 3.5´´ SATA HDD- 2.5´´ SATA HDD- 2.5´´ SATA SSD- Maximum Internal Raw Capacity: 80 TB (16 TB drive x 5) (Capacity may vary by RAID types)- Hot Swappable Drive: - RAID Management through Synology DSM: - Notes: It is strongly recommended that you only install drives listed on your device´s compatibility list.
