Synology DiskStation DS1525+ - Network-Attached Storage, Black

The Synology DiskStation DS1525+ is a 5-bay desktop NAS for centralized storage and network services. It houses five 3.5-inch or 2.5-inch SATA drives and supports RAID configurations including RAID 5, RAID 6, and Synology Hybrid RAID. An AMD Ryzen V1500B quad-core processor handles concurrent tasks and background operations. The unit includes 8 GB of DDR4 ECC memory, which detects and corrects errors to maintain data integrity. Two 2.5GbE Ethernet ports offer connectivity and support link aggregation to increase network throughput. Total raw storage capacity reaches 360 TB when paired with compatible expansion units.

The chassis features five hot-swappable drive bays, allowing for maintenance without system downtime. Two integrated M.2 NVMe slots enable SSD caching to improve the responsiveness of frequently accessed files. Cooling is handled by two 92 mm fans, which maintain an operating noise level of 22.6 dB. The device includes two USB 3.2 Gen 1 ports for external hardware or local backups. System management is provided by Synology DSM, which supports the Btrfs file system and point-in-time snapshots. Security options include AES encryption and access control lists for user permissions. Power is supplied by a 120 W external adapter, with a typical consumption of 44.56 W during operation.
