Synology DiskStation DS425+ 48 TB - Network-Attached Storage, Black

The Synology DiskStation DS425+ (48TB, 4x12TB HAT53) is a four-bay desktop storage server designed for home and small office environments. The unit comes pre-installed with four 12TB enterprise-grade hard drives, providing a raw capacity of 48TB. An Intel Celeron J4125 quad-core processor manages operations at a base frequency of 2 GHz. Two RJ-45 ports offer 2.5GbE connectivity for transfer speeds of up to 2,500 Mbit/s, with integrated Link Aggregation support for failover or increased throughput. The system runs on DiskStation Manager (DSM).

Two M.2 2280 NVMe slots allow for SSD cache acceleration without occupying the primary drive bays. The system is equipped with 2 GB of DDR4 SODIMM RAM, which is expandable to 6 GB. Dual 92 mm fans maintain an operational noise level of 21.6 dB. Data protection is managed via RAID 0, 1, 5, 6, or 10 configurations. External peripherals connect via two USB 3.2 Gen 1 ports. The hardware supports up to 512 concurrent connections and consumes 28.25 W during typical operation. The drive bays are hot-swappable, allowing for disk replacement without shutting down the system.
