3TB NAS Hard Drive

The Seagate ST3000VN000 is a 3TB 3.5 inch internal hard drive designed for 1- to 8-bay NAS systems. It uses a SATA 6.0Gb/s interface and includes 64MB cache. The drive is built for continuous 24x7 operation in multi-user environments supporting 20 users or less. It suits home or small office NAS towers and desktop RAID arrays.

NASWorks Technology Benefits

NASWorks technology provides customized error recovery controls to help prevent drives from being dropped during RAID rebuilds. Dual-plane balance improves vibration tolerance in multi-drive configurations. Advanced power management supports multiple profiles for low-power continuous operation. Quiet drive acoustics enhance the experience in living room or office settings.

Pre-Installation Checks

Verify your NAS or server has an available 3.5 inch drive bay and a SATA data plus power connection. Confirm the system supports 3TB capacity and the 26.11mm drive height. Bare drive packaging means no mounting screws or cables are included. Ensure your RAID controller or NAS firmware is compatible with NAS-optimized error recovery and vibration settings.
