Sporting 7200 RPM speeds in its' charmingly-familiar 3.5-inch form-factor, you might have to refamiliarize yourself with SATA cables, with the IronWolf Pro sporting the SATA III interface, for up to 6 Gb/s bandwidth, and speeds of up to 285 MB/s. The drive is rated for up to 550TB/year, with a Mean Time Between Failures of 2.5 million hours, or 285 years. That's a ton of data and uptime before a chance of failure. But with that said, you should probably still back things up, just in case.
This 28TB enterprise-grade HDD has a SATA III 6 Gb/s interface and spins at 7200 rpm. If you're looking for a single or replacement drive, you should check this deal out. Built for 24/7 operation, the IronWolf Pro is designed for sustained use and reliability.
As a further play for longevity, the drive has rotational vibration (RV) sensors for vibration tolerance and consistent performance in multi-bay systems. Also, if you're worried about any early failures, then the Seagate IronWolf Pro also comes with a 5-year limited manufacturer's warranty.
The 28TB model is identical to the 30TB model we reviewed in September 2025. Scoring 4 stars, it offers great maximum performance despite some quirks, making it more suited to heavy workloads than basic file storage. It's just about the best hard drive you can get for a NAS, as we've noted in our roundup. The only other drawback is the high base cost, negated somewhat by this deal. We've dropped some specific benchmarks below, so you have an idea of what performance looks like.
