3TB Desktop Hard Drive

This Seagate Desktop HDD provides 3TB of storage on a 3.5" SATA 6.0Gb/s interface with 64MB cache. It spins at 7200 RPM and targets desktop PCs, all-in-one systems, home servers and entry-level direct-attached storage. The bare drive arrives without cables or mounting hardware.

Upgrade from smaller mechanical drives

Moving to this model adds capacity with 1.33TB-per-disk technology and a SATA 6.0Gb/s interface that optimises burst performance. The jump is worth it when current storage is full or when faster sequential access matters for large media libraries and backups.

Standard 3.5" SATA installation

Mount the drive in any 3.5" bay using four screws, connect the SATA data and power cables, then initialise the disk in the operating system. Common issues include forgetting to enable AHCI in BIOS, using an old SATA cable that limits speed, or skipping the partition alignment step that Seagate SmartAlign handles for Advanced Format 4K sectors.

Questions about this item

What are the exact dimensions of the 3.5" drive so I can check bay clearance?

The drive measures 146.99 mm long, 101.60 mm wide and 26.11 mm high, matching the standard 3.5" form factor.

How do I connect this SATA 6.0Gb/s drive and what step do builders often miss?

Attach a SATA data cable to the motherboard port and a SATA power connector from the PSU; the step often missed is enabling AHCI mode in BIOS before installing the OS.

When should I expect to replace this 7200 RPM mechanical drive?

Plan replacement after three to five years of continuous use or if SMART attributes such as reallocated sectors begin to rise.
