Key specs

• Capacity: 12TB

• Duty cycle: designed for 24/7 continuous operation
• RAID: optimised for multi-bay NAS and RAID environments

The Toshiba N300 12TB is a NAS-class drive, not a repurposed desktop unit — the distinction that matters when speccing a recorder or file server that never powers down. Its 24/7 duty rating covers surveillance recorders, VMS servers and NAS enclosures running continuously across a shift pattern or unattended site.

Where it fits on a job

Use it as primary storage in multi-bay NAS boxes, as a RAID member alongside other N300 drives where consistent drive-to-drive behaviour matters, or as an archive/backup tier for footage and file data. The SATA III interface and 3.5" form factor mean it drops into any bay or recorder chassis built for that standard.

Performance notes

At 7200 RPM with a 256 MB cache buffer, the drive holds up under multiple simultaneous read/write streams — the pattern you get from several cameras writing to one array at once. Confirm the target NAS or NVR's per-bay capacity limit and RAID controller compatibility before allocating this drive into an existing array, since SOURCE does not specify maximum supported array size or controller list.
