Who it fits

Key specs for this drive

Form Factor: 3.5"

This physical size fits standard desktop computer bays and most NAS enclosures designed for larger drives. You need a chassis that accommodates these dimensions. Smaller 2.5-inch drives are for laptops or compact units. Check your enclosure compatibility before buying to ensure the drive fits properly and mounts securely.

Storage Capacity: 4TB

You get 4 terabytes of usable space for your files. This amount suits moderate libraries of photos, videos, and documents. Larger models offer more storage for extensive media collections. Compare this capacity with other drives to find the best balance between cost per terabyte and your specific storage needs for your NAS setup.

Hardware Interface: SATA

The SATA connection ensures broad compatibility with most motherboards and NAS controllers. You can plug it directly into standard ports without special adapters. This interface is widely supported and reliable for general storage tasks. Verify your system has available SATA ports to connect this drive easily alongside your existing hardware.

Model: MG04ACA400E

Design and Build Quality

The listing describes the Toshiba MG Series 4TB drive as a silver-colored unit with a standard 3.5-inch form factor. You get specific dimensions of 5.79 inches in length, 3.98 inches in width, and 1.02 inches in height. These measurements align with the internal bays found in most desktop towers and enterprise-grade NAS enclosures. The 1.02-inch thickness is typical for high-capacity platters, ensuring it fits in standard rack units without requiring specialized mounting hardware. You should verify your chassis supports this exact height, as some compact or older enclosures may have tighter clearances.

According to the listing, the drive weighs 1.59 pounds. This mass helps dampen vibrations during high-speed rotation, which is critical for a device rated for 24/7 operation. The SATA interface connects via a standard cable layout, making installation straightforward for users familiar with internal hard drives. There are no external controls, displays, or buttons on the unit itself. All management occurs through the host system or server software. The design prioritizes density and endurance over user interaction, fitting neatly into server racks or multi-bay storage arrays where space is at a premium.
