Product Features
Technical Overview
At its core, the N300 drive features a 16TB platter capacity using 512e (512-byte emulation) Advanced Format. The SATA/600 interface provides a 6 Gb/s data pathway, fully utilizing the drive's maximum sequential read and write transfer rates of 281 MB/s. This performance tier is backed by a substantial 512MB DRAM cache, which optimizes burst operations and improves responsiveness for mixed workloads.
The drive's mechanical design centers on a 7200 RPM spindle motor, balancing speed with power efficiency for always-on applications. Reliability metrics include a 180-terabyte written (TBW) endurance rating and a mean time between failures (MTBF) of 136.9 years, reflecting its build quality for continuous operation in supported devices.
Relevant factors for this section include Storage Capacity, Disk Format, Recording Technology, Maximum Read Transfer Rate. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
Key Product Advantages
The Toshiba N300 series is purpose-built for networked storage, offering several distinct advantages for IT buyers and system integrators. Its design prioritizes data integrity, sustained throughput, and compatibility with popular multi-bay enclosures and server chassis.
High-Capacity CMR Design
Utilizes Conventional Magnetic Recording, which avoids the write-performance limitations and complexity associated with SMR (Shingled Magnetic Recording) drives. This makes the N300 predictable and well-suited for RAID arrays, video surveillance storage, and frequently accessed data pools.
- Stable performance in RAID rebuilds
- No write amplification issues
- Ideal for random write workloads
NAS & Server Compatibility
Validated for use in network-attached storage systems, storage servers, general-purpose servers, and cloud storage platforms. The drive's firmware includes features like error recovery control and vibration compensation to maintain stability in multi-drive environments.
- Tested for 24/7 operation
- Supports TLER/ERC for RAID
- RoHS compliant construction
Deployment / Use Cases
This 16TB drive is a strategic component for expanding or building out capacity-centric storage solutions. Its blend of high density, strong sequential performance, and NAS-focused reliability makes it applicable across several professional and small business scenarios.
Primary deployment targets include multi-bay NAS units for centralized file sharing, backup targets, and media servers. It is equally capable as bulk storage in a tower or rackmount server handling data archives, surveillance video retention, or virtualization datastores where cost-per-terabyte is a key consideration.
Network-Attached Storage (NAS)
Populate 2-bay to 8-bay (or larger) NAS enclosures from vendors like Synology, QNAP, or Asustor to create a centralized repository for documents, multimedia libraries, and system backups. The drive's CMR architecture ensures consistent performance during simultaneous user access and background tasks like data scrubbing.
Server & Storage Expansion
Add high-capacity tiers to existing server storage pools or build new storage servers for departmental use. The SATA/600 interface ensures compatibility with a wide range of server motherboards and host bus adapters, while the 3.5-inch form factor fits standard drive bays in both tower and rackmount chassis.
Physical Profile
The drive conforms to the standard 3.5-inch hard drive form factor, measuring 1.03 inches (26.10 mm) in height, 4.01 inches (101.85 mm) in width, and 5.79 inches (147 mm) in depth. Its approximate weight is 1.59 pounds (720 grams). These dimensions ensure direct compatibility with virtually all desktop and server drive bays designed for 3.5-inch drives, whether using tool-less trays or requiring standard side-mounting screws.

User Manual
FAQ
What is the difference between CMR and SMR recording technology in this drive?
This Toshiba N300 drive uses Conventional Magnetic Recording (CMR), where data tracks are written side-by-side without overlapping. This differs from Shingled Magnetic Recording (SMR), where tracks overlap like roof shingles to increase density but can complicate write operations. CMR provides more consistent write performance, especially in RAID arrays or during heavy random write workloads, making it the preferred choice for NAS and server applications where data integrity and predictable performance are critical.
Is this hard drive suitable for use in a RAID array?
Yes, the Toshiba N300 HDWG51GXZSTA is designed and tested for RAID environments common in NAS and servers. It supports features like Time-Limited Error Recovery (TLER) or similar error recovery controls, which help prevent a drive from being dropped from the array during extended error recovery cycles. Its CMR technology also ensures stable performance during RAID rebuilds or resilvering operations, which is essential for maintaining array integrity.
What types of devices or systems is this hard drive compatible with?
This drive is validated for use in network-attached storage (NAS) systems, dedicated storage servers, general-purpose servers, and cloud storage platforms. It uses a standard SATA/600 interface and 3.5-inch form factor, making it physically and electronically compatible with most desktop computers, NAS enclosures, and server chassis that support SATA drives. Always verify your specific device's supported drive list and bay size (3.5-inch) before purchase.
What does the 180 TBW endurance rating mean for this drive?
The 180 Terabytes Written (TBW) endurance rating indicates the total amount of data the drive is designed to write over its lifespan under typical operating conditions. It is a measure of drive durability for write-intensive tasks. For context, writing 50GB of data per day would take nearly 10 years to reach this threshold. This rating, combined with the 136.9-year Mean Time Between Failures (MTBF), reflects the drive's robustness for continuous operation in supported environments like NAS or servers.
Does this drive require any special cooling or power considerations?
As a 7200 RPM 3.5-inch hard drive, it generates typical operational heat and should be installed in a chassis with adequate airflow, as recommended for any NAS or server environment. It uses a standard SATA power connector and operates on common +5V and +12V rails. No unusual power demands are present, but ensure your power supply or backplane can provide stable power, especially when populating multiple drives in an enclosure, to maintain optimal performance and reliability.
What is included in the retail package with this hard drive?
The drive is supplied in a retail package. While specific contents can vary, retail packages typically include the hard drive itself, possibly mounting screws, and documentation. For the exact contents of this specific SKU (HDWG51GXZSTA), please refer to the product packaging or the manufacturer's information.
