DiskStation DS423+
A compact storage hub with 100% data ownership
Conquer home office data chaos
• Capable and compact
Powerful functionality packed into a 4-bay chassis
• Consolidate and share
Store, organize, and share up to 72 TB of data.
• Integrated data protection
Contains hardware and software safeguards engineered to protect your data — trusted by millions.
A capable all-around performer
The versatile DS423+ can serve as a central storage device as well as a multimedia hub.
Up to 226/224 MB/s read/write
(Performance figures are obtained through internal testing by Synology. Actual performance may vary depending on the testing environment, usage, and configuration. See performance charts for more information.)
2 x M.2 NVMe SSD slots
(Synology SNV3400 series M.2 NVMe SSD drives can be installed through the built-in M.2 slots to enable SSD caching or create SSD storage pools. Drives are sold separately.)
2 x 1GbE LAN ports
Btrfs: advanced file system for data protection
The Synology DiskStation Manager (DSM) operating system that powers DS423+ uses the advanced Btrfs file system, which safeguards your data against corruption and allows for the reversal of any unintended or malicious changes through the use of snapshot technology.
Store, share, and protect
Manage all your documents, photos, and other files, back up applications and devices, and protect your physical assets with professional video surveillance.

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