Enterprise SAS drive
The Toshiba MG08SDA400E is a 4 TB 3.5-inch hard drive spinning at 7200 RPM with a 256 MB cache and a dual-port SAS 12 Gb/s interface. It is built for business-critical servers, storage arrays and cloud platforms that need high-capacity, reliable enterprise storage.
Suited for RAID and archive workloads
This drive fits mainstream enterprise arrays, distributed file systems, big-data clusters and centralised surveillance storage where a 550 TB yearly workload rating and sanitise instant erase options are valued. It is not for buyers who need a SATA interface, a smaller form factor or consumer desktop storage.
Dual-port SAS 12 Gb/s interface
The SAS 12 Gb/s connection provides dual-port redundancy and the throughput required by enterprise controllers and backplanes, making it the specification that determines compatibility with your storage infrastructure.

Questions about this item
How do I install the MG08SDA400E in a 3.5-inch bay and what step is often missed?
Mount the 3.5-inch 26.1 mm drive in the bay, connect the dual-port SAS 12Gb/s cables to the controller, and attach power. The step often missed is verifying the controller negotiates 12 Gb/s link speed on both ports.
What maintenance or replacement will the MG08SDA400E need during its service life?
Plan replacement once cumulative writes approach the 550 TB per year workload rating or when SMART attributes indicate wear. No scheduled mechanical maintenance is required for the sealed helium platform.
What limit appears first on the MG08SDA400E during sustained heavy writes?
The 550 TB per year workload rating is the first limit under sustained use; exceeding it reduces the expected service life of the 7200 RPM enterprise drive.
