NAS-optimised 4 TB hard drive

The Toshiba N300 HDWG440XZSTA is a 3.5-inch internal hard drive built for 24/7 network attached storage. It delivers 4 TB of capacity over a SATA 6.0 Gb/s interface, spins at 7200 RPM and includes a 256 MB cache to sustain multi-bay RAID workloads.

Suited for multi-bay NAS enclosures

This drive supports up to eight drive bays in a multi-RAID NAS design and is rated for 180 TB of writes per year with a 1,200,000 hour MTTF. It is not intended for single-drive desktop boot duties or for portable external use where vibration and power profiles differ.

SATA 6.0 Gb/s interface decides compatibility

The drive connects via a standard SATA 6.0 Gb/s port and requires a 3.5-inch bay with 26.1 mm height clearance. Systems limited to SATA 3.0 Gb/s or smaller form-factor bays will not be able to use this unit.

Questions about this item

Will the 3.5" 26.10 mm height fit in my existing NAS tray?

The drive measures 26.10 mm tall, 101.85 mm wide and 147.00 mm long, matching the standard 3.5" form factor used in most NAS trays.

Does the 7200 RPM speed and 256MB cache work with older SATA 3.0 Gb/s controllers?

The SATA 6.0 Gb/s interface is backward compatible, so the drive will operate on SATA 3.0 Gb/s ports at the controller's maximum throughput.

How can I confirm the 1,200,000 hour MTTF rating is being met after installation?

Monitor the drive's SMART attributes for reallocated sectors, seek errors and temperature; consistent values within specification indicate the rated reliability is being maintained.
