4 TB SAS Enterprise Drive

The Toshiba MG03SCA400 is a 4 TB 3.5-inch internal hard drive built for nearline server workloads. It spins at 7200 RPM with a 64 MB cache and connects through a SAS 6Gb/s interface. The bare drive is rated for continuous 24x7 operation in multi-drive environments.

Suited for RAID and nearline storage

This drive fits administrators who need consistent throughput and rotational-vibration tolerance in multi-bay chassis. Error Correction Code and Enhanced Power Condition State Technology help maintain data integrity and manage power during sustained use. Systems without a SAS host bus adapter or backplane cannot install this unit, and workloads demanding solid-state latency should consider a different storage tier.

SAS 6Gb/s interface decides compatibility

The single specification that determines fit is the SAS 6Gb/s interface; the controller or backplane must support this exact protocol. A 26.1 mm z-height matches standard 3.5-inch bays, while 147 mm length and 101.6 mm width follow the usual form-factor envelope. Verify the host connector and cabling before purchase.

Questions about this item

Will the MG03SCA400 work in my older server that only has 3Gb/s SAS backplanes?

Yes, the SAS 6Gb/s interface negotiates down to 3Gb/s so the drive will operate at the slower link speed without any configuration changes.

How can I verify the drive is running at 7200 RPM and using its 64MB cache after installation?

Check the SMART attributes or the controller BIOS — they report the spindle speed and cache size directly from the drive firmware.

The listing says "Bare Drive"; does the box include mounting screws, a SAS cable or a tray?

Only the 3.5-inch drive itself is supplied; mounting screws, SAS data cable and any hot-swap tray must be sourced separately.
