The Toshiba MG03SCA is a 3TB 6Gb/s SAS Enterprise HDD that has been the lynchpin of general storage for entry-level server workloads and capacity-intensive Tier 2 networked storage systems. The MG03 series, in both SATA and SAS flavors, has made its way into cloud, file, and object-based storage and disk-to-disk data protection applications.

We initially took a close look at the 4TB SATA variant, the MG03ACA400, in August of last year. This model features a 6Gb/s SATA connection, unlike the SAS model we are testing today, but shares many of the same performance characteristics.
