Seagate ST14000NM004J

Overview

The Seagate ST14000NM004J is a 14 TB internal hard drive designed for enterprise environments that require large-scale data storage and fast access. It fits into any 3.5-inch bay with a SAS backplane and delivers sustained transfer rates up to 270 MB/s via a 12 Gb/s interface. With a spindle speed of 7200 rpm, it ensures predictable latency and smooth streaming of large data sets, making it suitable for virtual machine backups, analytics platforms, and continuous data center operations.

Encased in a helium-sealed enclosure, this drive balances power consumption and throughput using PowerBalance technology, helping reduce energy costs without compromising performance. Real-time digital sensors monitor temperature and vibration to maintain optimal operating conditions and extend the drive’s lifespan. Its reliability is reflected in a mean time between failures (MTBF) of 2.5 million hours and a five-year limited warranty.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
