Reliable, compact and cost-effective 1 TB (1000 GB) enterprise-class internal hard drive from the Seagate Constellation.2 line of 2.5" HDDs, which includes 5 models ranging from 250 GB to 1 TB. This family includes high-quality server drives , the design and firmware of which are optimized for solving problems of long-term storage of information in NAS arrays and servers. They differ from 3.5" server drives in significantly smaller overall dimensions and reduced power consumption.

Designed for 24/7 operation in RAID arrays of blade servers and compact data storages. Standard SATA is used as the connection interface, so the Seagate Constellation.2 2.5" ST91000640NS hard drive can also be installed in ordinary desktop/office PCs and workstations. The classic CMR magnetic recording method provides high read/write speeds, and magnetic platters rotate at a speed of 7200 rpm, which reduces access time. The manufacturer claims best-in-class resistance to rotational vibration, ensuring stable performance when working in arrays of multiple drives.
