Synology DS723+ External HDD/SSD Overview

Enjoy strong performance and versatility while expanding your storage capacity with the Synology DiskStation DS723+ 2-Bay NAS Enclosure. Up to two separately purchased 2.5" / 3.5" SATA drives may be installed into this compact enclosure and configured for RAID 0, 1, Synology Hybrid, or JBOD modes. Two M.2 2280 SSD cache drives may also be installed to enhance performance, achieving maximum read and write speeds of 471 MB/s and 225 MB/s, respectively. The two Gigabit Ethernet ports may be linked together with link aggregation, allowing you to quickly backup and share data with connected devices.

The DiskStation DS723+ is designed for easy expansion so that it can adapt to your changing needs. This includes installing up to 32GB of ECC DDR4 memory and a 10G network upgrade module. The DiskStation Manager (DSM) operating system includes built-in file and photo management, data protection, virtualization, and surveillance solutions.

DiskStation DS723+


The Synology DiskStation DS723+ is powered by a 2.6 GHz AMD Ryzen R1600 dual-core processor with a 3.1 GHz boost speed and 2GB of ECC DDR4 memory to support fast and reliable data transfers. You can improve performance by installing up to a 32GB ECC DDR4 SO-DIMM memory module.

Network Connectivity

The two Gigabit Ethernet ports may be bonded using link aggregation, providing automatic network failover and load balancing. You may also add a 10G Network Upgrade Module to increase your bandwidth with compatible network devices.

Capacity Expansion

Connecting a separately available DX517 expansion unit to the eSATA port allows for a maximum of seven storage drives. External drives may also be connected to the USB-A 3.2 Gen 1 port.

Synology DiskStation Manager (DSM)

Data Protection & Integrity

Safeguard your critical data with the powerful storage management features of Synology DSM, built on the advanced Btrfs file system.

  • Advanced snapshot technology provides schedulable and near-instantaneous data protection for shared folders and LUNs.
  • File- and folder-level data restoration enables recovery of specific files or folders.
  • Flexible storage quota system helps admins manage available space by specifying storage limits for shared folders.
  • File self-healing detects and recovers corrupted files using mirrored metadata and RAID configurations.
  • Inline compression minimizes storage consumption and extends the life of drives by compressing data before it is written to the storage pool.

Data & Device Backup Solutions

Synology DSM comes standard with a complete package of backup solutions.

  • Active Backup Suite consolidates backup tasks and offers rapid restoration of Windows and Linux endpoints, VMs, Synology NAS, and SaaS applications.
  • Snapshot Replication creates point-in-time copies of shared folders and LUNs to protect them from accidental modifications or ransomware incidents.
  • Hyper Backup backs up your NAS data to multiple destinations securely and efficiently with integrity checks and powerful deduplication, compression, and versioning options.
  • C2 Storage for Hyper Backup offers a dedicated secure public cloud destination for Synology NAS backup data.

Collaboration and Sharing Tools

Synology's productivity suite provides a private cloud solution for on-site and remote workers to concurrently edit documents, share files, manage emails, send instant messages, and more.

  • Synology Drive is a cloud file management solution that supports file sharing, remote data access, cross-device and cross-site synchronization, on-demand file restoration, and backup.
  • The Synology Office extension lets users collaborate on documents, spreadsheets, and presentation slides in real time, supported by convenient options such as file versioning for easy restoration and password protection.
  • Synology Photos serves as a media organization hub for enthusiasts and professionals looking to efficiently manage and share their photos and videos through intuitive browsing options and secure sharing methods.
  • Synology Hybrid Share combines reliable on-premises storage and efficient syncing of shared folders in the cloud to enable seamless cross-site synchronization and local file access at LAN speed.

Private Video Surveillance

  • 8,300+ supported camera models.
  • ONVIF support for a broader selection of cameras.
  • Private, subscription-free storage of recordings.
  • Access through web browsers, desktop clients, or mobile apps.
  • Event-based rules to trigger specific actions.
  • Email, SMS, and push notification options.

Virtualization & Certified Storage

Your DS723+ can serve as virtual machine storage, VM backup server, and a lightweight container and VM host. It is fully certified as storage for VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack environments.

  • Synology Storage Console for VMware or Windows platforms lets you manage VM storage components directly from your hypervisor. VMware VAAI integration and Windows ODX help offload storage operations and speed up data transfer.
  • Host light containers and VMs for testing, sandboxing, and emergency recovery purposes with Docker and Synology Virtual Machine Manager, a native hypervisor that supports Windows, Linux, and Virtual DSM10.
