Capacity and purpose

The Toshiba MD04ACA400 is a 4TB 3.5-inch desktop hard drive built for daily computing. It suits users who need a large warehouse for game libraries, movies, photos and music. The SATA 6.0Gb/s interface, 7200 RPM spindle speed and 128MB cache combine to keep everyday tasks responsive.

Sustained workload behaviour

At 7200 RPM with a 128MB buffer the drive maintains steady throughput during long file transfers or extended gaming sessions. Average latency of 4.17ms helps keep access times consistent when the drive is under continuous load. Native Command Queuing support lets the controller reorder requests for smoother multitasking.

Installation checklist

Verify your chassis has a 3.5-inch bay with at least 147mm length, 101.6mm width and 26.1mm height clearance. Confirm the motherboard or controller provides a free SATA 6.0Gb/s port and that your power supply includes a spare SATA power connector. The drive ships as a bare unit without cables or mounting screws.

Questions about this item

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

The drive spins at 7200 RPM with a 4.17 ms average latency; typical desktop workloads keep it within normal acoustic and thermal ranges for a 3.5-inch SATA drive.

What cables and power connectors must I already have to install this SATA 6.0 Gbit/s drive?

A SATA data cable and a SATA power connector from the power supply are required; the drive uses the standard 3.5-inch form factor with a 26.10 mm height.

Will the 4 TB drive work alongside my older SATA 3 Gbit/s motherboard port?

Yes, the SATA 6.0 Gbit/s interface is backward compatible with earlier SATA revisions, so the drive will operate at the slower link speed on older ports.
