With the DS423+, you can easily create a centralized storage solution for all your data and media files, including photos, videos, music, and documents. It supports a variety of RAID configurations, including RAID 0, 1, 5, 6, and 10, giving you flexible options for data protection and redundancy.

The DS423+ also offers advanced data management features, such as file syncing, sharing, and backup, allowing you to access your files from anywhere and easily collaborate with others. It supports multiple user accounts and access permissions, so you can control who can access your files and what they can do with them.

The DS423+ is equipped with two Gigabit Ethernet ports and supports link aggregation, allowing you to increase network bandwidth and improve data transfer speeds. It also has two USB 3.0 ports and an eSATA port for external storage expansion, as well as an optional PCIe 2.0 x8 slot for adding additional functionality, such as a 10GbE network card.
