Synology HAS5300-16T 3.5" 16 TB Internal HDD

The Synology HAS5300-16T is a high-performance, enterprise-grade 3.5-inch SAS-3 hard disk drive designed for demanding storage systems such as high-density NAS, SAN, or file server deployments. Boasting 16 TB of capacity and a fast 12 Gb/s SAS interface, it spins at 7,200 RPM and includes a 512 MiB cache buffer, allowing exceptional sustained data throughput of approximately 262–275 MB/s. It’s engineered for 24/7 enterprise use, with a workload rating up to 550 TB transferred per year, and an impressive Mean Time Between Failures (MTBF) of 2.5 million hours, ensuring reliability under heavy workloads. Built with power efficiency in mind, it draws about 8.12 W during active operations and ~4.46 W when idle. The drive is also hardened for enterprise environmental stress: wide operating temperature range (5°C to 60°C), shock / vibration tolerance, and includes persistent write cache technology to protect against data loss during power interruptions. Synology backs it with a 5-year limited warranty, extensive firmware and compatibility testing (200,000+ hours) with Synology hardware, plus integration with DSM for drive health monitoring, firmware updates, and optimized RAID-array repair performance.
