The DS923+ 4-Bay NAS Enclosure from Synology is a capable solution that can be adjusted and expanded as your needs change, with optional support for up to nine drives, faster networking, and two M.2 2280 NVMe PCIe 3.0 x4 SSD slots for caching or additional storage pools. Powered by Synology DiskStation Manager (DSM), it offers a flexible all-in-one solution for data sharing, synchronization, backup, and surveillance. The DS923+ is equipped with four drive bays that are capable of natively supporting 3.5 SATA III hard drives, as well as 2.5 SATA III hard drives and SSDs.

The DS923+ runs on Synology DiskStation Manager (DSM) OS, which is a browser-based operating system that helps to simplify managing your Synology NAS . Its CPU is a 2.6 GHz AMD Ryzen R1600 Dual-Core with a burst frequency of up to 3.1 GHz, and its 4GB of DDR4 RAM, which can be upgraded to 32GB, allows frequently used files and applications to be quickly accessed. This NAS is capable of sequential read speeds up to 625 MB s and sequential write speeds up to 559 MB s.

Also featured are two USB-A 3.2 Gen 1 ports that allow it to be connected to external storage or other USB devices, an eSATA port for the DX517 expansion unit, and network connectivity is achieved via the dual integrated Gigabit Ethernet ports that support link aggregation and failover, allowing your stored data to be shared with users throughout the network. For those who require RAID support, the DS923+ 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.

The DS923+ is engineered to be energy efficient and its dual 92 x 92mm fans to help keep the system running cool at all times. The server supports numerous scheduled power on off cycles and hard drive hibernation to further minimize power consumption and operation expenses.

The Synology DiskStation DS923+ 4-Bay NAS Enclosure operates on 100-240 VAC at 50 60 Hz and includes an accessory pack, an AC power adapter, an AC power cord, and two RJ45 LAN cables. It is protected by a limited 3-year warranty.

Versatile Storage for Any Purpose

The DS923+ comes out of the box with intuitive and comprehensive file management, media organization, and backup options, making it ideal for IT enthusiasts, creative professionals, and business owners looking for a powerful and compact storage system.

Up to 625 MB s sequential read and 559 MB s sequential write performance enable fast file sharing, syncing, streaming, and backup for multiple users.

Supports 4 x 3.5 or 2.5 SATA HDD SSD, expandable to 9 drives with one Synology DX517 expansion unit

Up to 32GB of DDR4 ECC memory offers protection against potential crashes and inadvertent changes in data through automatic correction of data errors.

Two Gigabit RJ45 ports can be bonded using Link Aggregation to provide automatic network failover and load balancing.

Notes

Usable capacity for each volume will be lower than the maximum volume size and is dependent on the filesystem and the amount of system metadata stored.

Creating M.2 storage pools requires the use of Synology-verified SSDs, which are rigorously tested under extreme temperature conditions. Thermal parameters for SSDs and NAS units are fine-tuned to ensure optimal management of thermal conditions under I O-intensive environments. (Learn more )

Actual maximum storage pool and volume sizes depend on drive sizes used, the number of drive bays available, and the RAID configuration.

Each internal volume (may consist of multiple drives) is expandable up to 108TB.
