Enterprise storage drive

The Toshiba MG03ACA400 is a 4TB 3.5-inch internal hard drive built for 24x7 enterprise workloads. It delivers 7200 RPM performance over a SATA 6.0Gb/s interface with a 64MB cache. This unit suits server arrays, backup targets and tiered cloud infrastructure requiring sustained throughput.

Bare drive mounting and vibration tolerance

Supplied as a bare drive, it fits standard 3.5-inch bays with a 26.1 mm z-height. Rotational Vibration Technology maintains stability when installed alongside multiple drives in dense enclosures. The SATA connector and power pins follow the familiar layout for quick integration into existing caddies or backplanes.

Capacity and speed decision point

At 4TB and 7200 RPM this model sits at the top of the MG03ACA line for single-drive capacity. Buyers needing more storage per bay must look beyond this series. The SATA 6.0Gb/s link caps peak transfer, so workloads demanding higher bus bandwidth will not be satisfied.

Soalan tentang produk ini

Does the SATA 6.0Gb/s interface limit real-world throughput to the 6 Gbit/s line rate?

The SATA 6.0Gb/s link caps burst transfers at 6 Gbit/s; sustained sequential reads from the 7200 RPM platters typically run well below that ceiling.

Will the 26.1 mm height fit a standard 3.5-inch drive bay or hot-swap tray?

Yes, the industry-standard 3.5-inch 26.1 mm form factor matches common server bays and desktop cages without adapters.

Is any jumper or BIOS setting required to enable the 6.0Gb/s link on this bare drive?

No jumpers are needed; the drive auto-negotiates 6.0Gb/s on any compliant SATA controller, but the host must also support 6 Gbit/s.
