The Seagate ST28000NM003K internal hard drive is a high-performance storage unit designed for professional and enterprise environments requiring large capacity and reliability. With an impressive 28 TB capacity , this device uses conventional magnetic recording ( CMR ) technology and features a helium-sealed design that reduces internal friction and improves thermal efficiency, enhancing durability and performance. Its spindle speed is 7,200 rpm , suitable for fast response in applications demanding continuous access to large data volumes. It includes a SATA interface with maximum transfer speeds up to 6 Gb/s , ensuring compatibility and solid performance on standard platforms. Additionally, it has a 512 MB multi-segment cache that enables efficient handling of intermediate data and improves read/write speeds. The unit incorporates advanced reliability technologies such as super parity and RSA 3072 firmware verification, maintaining a low unrecoverable error rate (only 1 sector per 10 15 bits read), reflecting high stability. Its robustness is evident in features like a mean time between failures ( MTBF of 2,500,000 hours ) and a low annual failure rate ( AFR of 0.35% ), ensuring continuous operation without interruptions over long periods, with shock and vibration tolerance both in operation and at rest. The design also optimizes power consumption, averaging just 6.9 W at idle and a maximum of 9.5 W during intensive read/write operations , facilitating efficient energy management in data centers or integrated systems. Regarding dimensions, the drive has a standard 3.5-inch size (26.1 x 101.85 x 147 mm) and weighs 695 grams , suitable for installation in conventional bays. It also supports hot-swapping, allowing replacement without shutting down the system, increasing operational flexibility. This model also features additional technologies like PowerChoice and PowerBalance, which optimize power use based on load and usage conditions, and is built with low-halogen materials for greater environmental sustainability. In summary, the Seagate ST28000NM003K is a high-capacity, high-performance internal SATA magnetic HDD, especially suited for critical workloads requiring massive storage, proven reliability, and energy efficiency in demanding professional environments.
