12TB NAS hard drive for multi-bay enclosures

The Toshiba N300 HDWG51CUZSVA is a 12TB desktop internal hard drive built for network-attached storage systems. It targets home and small-business users who need large-capacity, always-on storage in a 3.5-inch form factor. The drive is new and uses conventional magnetic recording technology.

CMR recording technology for RAID arrays

The single specification that determines suitability is the CMR recording technology. Unlike shingled magnetic recording drives, CMR writes data in parallel tracks without overlapping, delivering consistent write performance during rebuilds and sustained RAID workloads. This makes the drive appropriate for multi-drive NAS environments where steady throughput matters.

7200 RPM with 512MB cache under continuous operation

At 7200 RPM and with a 512MB cache, the drive maintains stable transfer rates during long sequential reads and writes typical of NAS duties such as backups, media streaming and file sharing. The SATA 6.0Gb/s interface does not saturate under these sustained loads, so the mechanical speed and cache depth define real-world throughput rather than burst-speed figures.

Perguntas sobre este artigo

What does the 7200 RPM speed mean for real-world NAS workloads?

The 7200 RPM spindle keeps platters spinning fast enough to sustain the throughput multi-bay NAS arrays need for concurrent media streams and backup jobs.

How does the SATA 6.0Gb/s interface limit actual transfer rates?

The SATA 6.0Gb/s link sets the electrical ceiling; the drive’s own 512MB cache and CMR recording determine the sustained rates you will see.

Will the 3.5" form factor fit my four-bay NAS chassis?

The 3.5" form factor matches the standard drive bays used in virtually all four-bay and larger NAS enclosures.
