14 TB Enterprise NAS Drive

The Toshiba N300 Pro HDWG51EXZSTB is a 14 TB internal hard drive built for business network-attached storage. It targets administrators who need high-capacity, reliable storage for multi-bay NAS enclosures running continuous workloads.

SATA 6.0 Gb/s 3.5" Integration

The drive connects via a standard SATA 6.0 Gb/s interface and fits a 3.5 inch bay with a 26.10 mm height profile. Its 512 MB cache buffers heavy I/O, while built-in RV sensors counteract rotational vibration in arrays of up to 24 drives, freeing the system from vibration-related performance drops.

300 TB/Year Workload Headroom

Rated for a 300 TB per year workload, the CMR drive comfortably handles 24/7 operation in RAID-optimised NAS systems serving medium or large businesses. It runs out of headroom when workloads exceed the annualised limit or when a deployment requires more than 24 drive bays.

商品問答

What is the annual workload limit for this 14TB N300 Pro drive?

The drive is rated for up to 300 TB per year, which is the sustained-use limit that appears first under heavy NAS workloads.

How does the built-in RV sensor affect heat and noise during 24/7 operation?

The RV sensors counteract rotational vibration in multi-bay arrays, helping the drive run cooler and quieter during continuous operation.

Which SATA host controller or backplane is required for the 6.0Gb/s interface?

Any standard SATA 6.0Gb/s controller or backplane will work; the drive uses the common SATA data and power connectors.
