The Synology HAT5300-12T is an enterprise-grade 3.5-inch hard drive designed for the demanding environments of datacenters and professional NAS setups. With a capacity of 12 TB and a rotational speed of 7200 RPM, it provides the necessary throughput for high-traffic workloads, supported by a 256 MB cache and a SATA 6Gb/s interface for efficient data transfer. Built for continuous 24/7 operation, this drive features a workload rating of 550 TB per year and a mean time between failures of 2.5 million hours. It incorporates Persistent Write Cache Technology, which helps protect your information by minimizing the risk of data corruption during sudden power losses. The drive operates quietly, with noise levels ranging from 25 dB when idle to 32 dB during seek operations, and maintains a low power profile between 5.0 W and 7.0 W. This hardware is particularly suited for administrators who need a reliable storage foundation that is tightly integrated with Synology hardware and DSM. Its robust construction and an unrecoverable read error rate of 1 per 10^15 bits ensure that large-scale data archives remain stable and accessible over the long term.
