The Synology HAT3310-12T is an internal hard drive specifically engineered for NAS environments, providing a substantial 12 TB of storage capacity. It utilizes Conventional Magnetic Recording (CMR) technology and a SATA III interface to ensure stable data writes and a maximum sustained transfer rate of 281 MB/s. With a rotational speed of 7200 RPM and a 512 MB cache, this 3.5-inch drive is built to handle the continuous demands of a network-attached storage system. To maintain long-term reliability, the drive features a helium-sealed design that reduces friction and power consumption, drawing only 6.85 W during active use. It has undergone 500,000 hours of rigorous testing and boasts an MTBF of 1.2 million hours, supporting a yearly workload of up to 180 TB. This makes it a dependable choice for users who need a high-capacity volume for constant data access and archival. Integration is simplified through the Synology DSM, which allows you to perform firmware updates directly on the drive. Weighing 720 g and measuring 147 x 101.85 x 26.11 mm, it fits standard NAS bays while operating efficiently across a temperature range from 5 to 60°C.
