NAS-ready 4 TB hard drive

The Toshiba N300 HDWG440XZSTA is a 3.5-inch internal hard drive built for 24/7 network attached storage. It suits personal, home-office and small-business NAS enclosures that need continuous operation. The drive delivers 4 TB capacity over a SATA 6.0Gb/s interface with a 7200 RPM spindle and 256 MB cache.

Thermals noise and power in normal use

Rotational vibration sensors automatically detect and compensate for transient vibrations in multi-bay chassis, helping the drive run steadily under typical NAS workloads. The 180 TB per year workload rating reflects the endurance expected during everyday file serving and backup tasks. A 1,200,000 hour MTTF figure supports the design goal of round-the-clock power-on operation.

Behaviour under sustained load

Support for up to 8 drive bays in a multi-RAID configuration lets the drive maintain consistent throughput as the array scales. RV sensors continue to counteract vibration-induced latency during prolonged, heavy I/O sessions. The combination of 7200 RPM speed and large cache sustains performance for large sequential transfers and concurrent user access.

Questions about this item

How do I install the 3.5" SATA drive in my NAS, and which step is often missed?

Mount the drive in a 3.5-inch bay using four screws, connect the SATA 6.0Gb/s data cable and the SATA power cable, then ensure the NAS firmware recognises the new volume before creating any RAID array.

What maintenance or replacement will the drive need during its service life?

The drive is rated for 1,200,000 hour MTTF and a 180TB per year workload; monitor SMART attributes for reallocated sectors and plan replacement if the error rate rises or the workload limit is consistently reached.

What limit appears first during sustained 24/7 operation in a multi-bay NAS?

Rotational vibration sensors compensate for transient vibration up to eight drive bays, so the practical limit is the 180TB annual workload rating rather than vibration-induced performance loss.
