Synology Plus Series HAT3310 12TB 7200 RPM NAS Hard Drive

The Synology Plus Series HAT3310-12T is a 12TB 3.5-inch hard drive purpose-built for Synology NAS systems. Engineered for continuous 24/7 multi-user workloads, it uses 100% conventional magnetic recording (CMR) technology to deliver consistent write performance throughout its operational lifespan — avoiding the performance variability associated with shingled magnetic recording (SMR) designs. Synology subjects Plus Series drives to over 500,000 hours of compatibility and stress testing within its own hardware ecosystem. This rigorous validation process helps ensure that the HAT3310-12T operates reliably in Synology enclosures under sustained workloads such as surveillance storage, small-business file sharing, and data backup. Firmware management is handled directly through Synology DiskStation Manager (DSM), enabling administrators to apply updates without physically removing the drive from the enclosure. This integration simplifies routine maintenance and reduces downtime in deployed NAS environments. The drive spins at 7,200 RPM and achieves a maximum sustained data transfer speed of 281 MB/s, making it well-suited to throughput-intensive applications. A 512 MB cache buffer supports read-ahead and write-back operations to smooth sequential and mixed I/O patterns. The HAT3310-12T connects via a SATA 6 Gb/s interface and fits any standard 3.5-inch drive bay. Power consumption in active idle is rated at 3.30 W, rising to 6.85 W under random read/write (4 KB Q1) workloads, reflecting the drive's energy profile during typical NAS operation.
