Dell 1 TB SATA hard drive

This 2.5-inch drive adds 1 TB of storage to compatible Dell systems through a SATA 6.0Gb/s connection. It spins at 7200 RPM and uses SLC NAND flash memory for caching. The drive is sold new and may arrive in retail or OEM packaging.

Sustained load behaviour

The 7200 RPM spindle speed supports consistent sequential throughput during extended read and write sessions. SLC cache helps absorb write bursts without the sharp slowdowns seen on drives that rely on TLC or QLC memory. Mechanical latency remains the limiting factor for random workloads under continuous pressure.

Installation and common issues

Mount the drive in any 2.5-inch bay and connect the standard SATA data and power cables; no extra drivers are required for the SATA interface. The most common problems are using a 3.5-inch bracket without an adapter, connecting to a SATA 3.0Gb/s port which halves the link speed, and forgetting to initialise the disk in the operating system before use.

商品問答

How much heat and noise does the 7200 RPM 400-ATJG produce during all-day operation?

The 7200 RPM spindle and SATA 6.0Gb/s interface generate typical mechanical-drive warmth and audible seek noise; ensure your chassis has adequate airflow for 2.5" bays.

What must my system already provide for the 400-ATJG to work?

A free 2.5" drive bay, a SATA data cable and a SATA power connector from the power supply are required for installation.

Will the 400-ATJG run reliably alongside an older 3 Gbps SATA drive in the same machine?

Yes — the SATA 6.0Gb/s interface auto-negotiates down to 3 Gbps, so the 1 TB drive will operate normally on legacy ports.
