Toshiba N300 18TB NAS Hard Drive 3.5" SATA 7200RPM

The Toshiba N300 18TB is a 3.5" SATA NAS hard drive built for 24/7 operation in multi-bay storage systems. For trade buyers speccing storage for NAS appliances, file servers or surveillance recorders, that continuous-duty rating is the deciding factor over a standard desktop drive.

Where it fits on a job

• NAS deployments: multi-bay NAS units for offices, retail back-rooms or residential blocks needing shared file storage or backup targets
• Surveillance storage: NVR/DVR systems recording continuously across multiple cameras, where large capacity and sustained write performance matter
• File servers and archiving: business platforms needing dependable large-capacity storage under constant workload

Key specs

• Capacity: 18TB
• Interface: 3.5" SATA III, 6 Gb/s
• Spindle speed: 7200 RPM
• Cache: large buffer for sustained data performance
• Built to run continuously, 24 hours a day, 7 days a week.
• Optimisation: built for RAID and multi-drive NAS environments

Selection notes for installers

The SATA III interface matches most current NAS enclosures and NVR bays, but always confirm the drive size and interface your specific unit supports before ordering — some older hardware has capacity ceilings. When populating multiple bays for RAID, matching drives across the array (same model, same capacity) helps keep rebuild times and performance predictable.

This drive suits jobs where downtime isn't an option: surveillance recorders that run around the clock, or NAS boxes serving as the single point of file access for a site.
