we present the Hard Drive Seagate ST30000NM004K 3,5" The Seagate ST30000NM004K hard drive is a high-capacity internal unit designed for systems requiring massive, reliable storage. With an impressive 3.5-inch size and a 30 TB capacity, this hard drive uses conventional magnetic HDD (CMR) technology and a helium-sealed design to improve efficiency and reduce mechanical wear. The 7200 rpm spin speed combined with a 6 Gb/s SATA interface allows continuous data transfer rates up to 275 MB/s, meeting performance needs for enterprise applications or large data storage. Its 512 MB segmented cache helps optimize read/write operations, while supporting advanced features like PowerChoice and PowerBalance technologies that optimize power consumption, with an average idle power of just 6.9 W. This model is specially designed for demanding environments, with high reliability certified by a 2,500,000-hour mean time between failures (MTBF) and an extremely low unrecoverable read error rate. Its durability includes tolerance to both operational and non-operational vibrations, plus high shock resistance to ensure data integrity under intensive use. With compact dimensions of 26.1 x 101.85 x 147 mm and a light weight of 695 grams, this hard drive is compatible with most chassis and systems supporting standard SATA drives. Its hot-plug support facilitates installation and maintenance without downtime in servers or workstations. For all these features, the Seagate ST30000NM004K represents a robust and efficient solution for businesses and professionals needing massive, reliable storage optimized for constant, demanding workloads.
