Synology DS425+ 4-bay NAS with Intel CPU and 2x USB ports

The Synology DiskStation DS425+ is a compact, 4-bay network-attached storage (NAS) device designed for efficient data management, backup, and multimedia applications. It features a diskless design that allows users to install their own 3.5-inch hard drives, providing flexibility in storage configuration. At its core lies the Intel Celeron J4125 processor, which ensures reliable performance for everyday tasks while maintaining energy efficiency. The device is equipped with 2 GB of DDR4 onboard memory, which can be expanded to a maximum of 6 GB by adding the D4NS01-4G module, enhancing multitasking capabilities and system responsiveness.

Network connectivity is robust, featuring one Gigabit Ethernet port and one 2.5 Gigabit Ethernet port, enabling high-speed data transfer and efficient communication with local networks or external devices. This setup supports advanced features such as Snapshot Replication, which helps in backing up critical data and significantly reduces Recovery Time Objective (RTO), ensuring minimal downtime in the event of data loss or corruption.

The DS425+ includes two built-in M.2 2280 NVMe SSD slots that can be used for cache acceleration without occupying any of the storage drive bays. These slots support the Enterprise Series SNV3400 NVMe SSDs, offering enhanced read and write speeds that improve overall system performance and reduce latency during intensive operations.

For surveillance applications, the DS425+ is capable of supporting up to 25 IP cameras simultaneously. It can handle a total of 750 frames per second at 720p resolution using H.264 compression. This makes it ideal for small to medium-sized security systems where real-time monitoring and recording are essential. The device comes with two free camera licenses included; additional licenses must be purchased separately to support more cameras.

Storage options are diverse and tailored to different performance needs. The DS425+ supports various hard drive series including the Enterprise Series HAT5300 for high-performance SATA drives and HAT3300 for reliable SATA drives in the Plus Series. For faster access speeds, users can also utilize the SAT5200 Series of 2.5-inch SATA SSDs, providing an optimal balance between speed and capacity.

The compact form factor of the DS425+ makes it suitable for desktop environments without compromising on functionality or performance. Running on Synology DiskStation Manager (DSM), this NAS serves as an all-in-one solution for data sharing across multiple devices, cloud synchronization, automated backups, and centralized surveillance management.

In summary, the Synology DiskStation DS425+ offers a versatile platform combining powerful processing capabilities with flexible storage configurations and advanced networking features. It is an excellent choice for individuals or small businesses seeking a reliable NAS solution that supports both data management needs and security surveillance requirements efficiently and effectively.
