When your business data grows faster than your storage can keep up, you need a drive that never slows down or fails. The Western Digital Red Pro WD161KFGX (4 PACK) 16 TB / 512 MB 3.5″ Hard Drive is a purpose-built NAS hard drive that delivers massive capacity and relentless reliability for 24-bay systems, so your team can share, back up and archive files without interruption.
Benefits of Western Digital Hard Drive
You enjoy uninterrupted access to critical files thanks to a 2 500 000-hour MTBF and a 550 TB/year workload limit, which means the drive can handle heavy daily traffic. The built-in NASware 3.0 firmware reduces error recovery time, giving you smoother RAID performance and fewer drive drop-outs. Multi-axis shock sensors protect data during accidental bumps, while 3D Active Balance Plus keeps vibration low, extending the drive’s life. Low idle power (3.6 W) and standby consumption (0.9 W) lower your electricity bill and keep the NAS cool.
Key Features of a 16 TB Hard Drive
- Capacity: 16 TB. Vast space for backups, media libraries and archives.
- Buffer size: 512 MB. Large cache speeds up read/write bursts for smoother file transfers.
- Interface: Serial ATA. Standard connection ensures easy installation in any compatible NAS.
- Speed: 7200 RPM. Fast spindle speed reduces latency for quicker data retrieval.
- Transfer rate: 259 MB/s. High throughput supports demanding workloads and large file streams.
- Power (read/write): 6.1 W. Efficient energy use during active operations.
- Shock protection (operating): 30 G. Handles sudden movements without data loss.
- Shock protection (non-operating): 250 G. Safeguards the drive when the system is off.
- Operating temperature: 0 - 65 °C. Reliable performance in typical server rooms.
- Weight: 690 g. Sturdy yet manageable for rack mounting.
Usages of a 16 TB Hard Drive
Ideal for any scenario where large, reliable storage is essential:
- Centralised file server for multiple office locations.
- High-capacity video surveillance storage with continuous recording.
- Backup repository for critical business applications and databases.
- Media production archive for 4K footage and large project files.
- Cloud-sync gateway storing synced copies of remote data.
Western Digital Hard Drive
Many buyers worry that a single hard drive cannot cope with the constant read/write cycles of a busy NAS, leading to frequent rebuilds and data loss. Others fear that high capacity means higher power draw and heat, which can shorten component life. These concerns often result in over-specifying or under-investing in storage solutions.
The Western Digital Red Pro WD161KFGX (4 PACK) 16 TB Hard Drive removes that doubt. Its extended thermal-cycle burn-in testing guarantees stability under 24-bay load, while NASware 3.0 and error-recovery controls keep RAID arrays healthy. With a low power profile and robust shock protection, the drive stays cool and safe, delivering the capacity you need without the hidden costs of failure or excess energy use.
