Hard Drives / Toshiba Enterprise Hard Drives

Toshiba MG series nearline drives for NAS systems, backup servers and bulk file storage, built for around the clock operation and listed by exact Toshiba model code so the replacement matches the original.

The Toshiba MG04 in This Range

The MG04ACA200NY is a 2TB 7200 RPM SATA drive in the 3.5-inch form factor from Toshiba's MG enterprise capacity family. The model code breaks down in a useful way: MG04 is the generation, ACA marks the SATA interface and 200 is the capacity. MG drives are rated for continuous 24/7 operation and much higher annual workloads than desktop disks, which is why they show up in small business NAS units, surveillance recorders and entry level storage servers.

When a 2TB Nearline Drive Is the Right Choice

Not every replacement should be the largest drive available. Many RAID controllers and NAS units expect every member of a volume to share the same capacity, and adding a larger disk simply wastes the extra space until every drive is upgraded. A like for like 2TB replacement restores redundancy immediately without a migration project. For sequential workloads such as backup and recording, a 7200 RPM SATA drive is entirely adequate.

Checking Compatibility First

NAS vendors publish compatibility lists, and some units warn about drives outside that list even when they work correctly. Send us the NAS or server model and we will confirm the fit before dispatch. If your workload is latency sensitive rather than sequential, compare a 10K or 15K drive using our drive speed guide, or see every Toshiba product on the Toshiba brand page.
