Capacity and intended use

This 1 TB hard drive operates at 7.2K RPM with a SATA 6 Gbps interface and 512 n sector formatting. It suits desktop systems and entry-level servers that need bulk storage for archives, backups or secondary data volumes.

Build and connectivity

The 2.5 inch form factor fits standard drive bays and hot-swap trays that accept SATA connectors. Firmware is updated and each unit is tested before dispatch so installation proceeds without additional preparation.

Thermals and power

Spindle speed of 7.2K RPM keeps heat output moderate for continuous operation in multi-drive enclosures. Acoustic profile remains low enough for office environments and power draw stays within typical SATA limits.

Questions about this item

Does the SATA 6Gbps interface limit the drive's maximum transfer rate?

The SATA 6Gbps interface sets a theoretical ceiling of 6 Gbps for the ST91000640NS drive.

Will this 2.5in drive fit a standard 3.5in desktop bay?

The 2.5in form factor requires an adapter bracket to mount securely in a 3.5in bay.

How is the 512n sector format handled during installation?

The drive uses native 512-byte sectors, so no jumper settings or alignment tools are needed; it is recognised automatically by the BIOS.
