Enterprise storage capacity

The Toshiba MG11ACA20TE delivers 20TB of capacity in a 3.5-inch form factor for desktop and server workloads that require high-volume data retention. Its 7200 RPM spindle speed supports sustained sequential throughput for bulk storage, backup targets and media archives. The drive is built for always-on environments where total capacity per bay is the primary design constraint.

SATA host integration

The drive connects through a standard SATA-3.5a interface and fits any 3.5-inch drive bay with matching power and data cables. No proprietary controllers, caddies or PCIe lanes are required, so it can be added to existing backplanes or external enclosures without chassis changes. The 512e format ensures compatibility with legacy operating systems and RAID controllers that expect 512-byte logical sectors.

Format flexibility included

The 512e/4Kn* capability lets administrators choose between 512-byte emulation and native 4Kn sector modes depending on the host platform. This dual-format support reduces migration friction when moving arrays between older and newer controllers. No additional software licences or firmware tools are bundled beyond the drive’s native firmware feature set.

Questions about this item

What is the maximum sustained throughput the SATA 6 Gb/s interface can deliver on this 7200 RPM drive?

The SATA 6 Gb/s interface supports up to 6 Gb/s, but the 7200 RPM platters typically sustain lower sequential rates in real workloads.

How much heat and noise does the 3.5-inch 7200 RPM mechanism produce during continuous operation?

Enterprise 3.5-inch 7200 RPM drives run warmer and louder than lower-speed models; expect noticeable vibration and heat under all-day loads.

Which host controller and cable are required to connect this SATA drive to a desktop system?

A standard SATA host port and a SATA data cable are needed; the drive uses the SATA-3.5a interface and draws power from a standard SATA power connector.
