Seagate IronWolf 4TB NAS Internal Hard Drive (10-Pack)

The Seagate IronWolf 4TB is a hard drive with a clear job description: keep a network attached storage box running around the clock. It is a 3.5-inch SATA 6Gb/s unit that spins at 5400 RPM and carries a 64MB cache. What distinguishes it from a generic desktop drive is the use of CMR, or conventional magnetic recording, a trait that matters in RAID setups where the sustained, overlapping writes of a shingled drive can slow rebuilds. Seagate aims this drive squarely at up to 8-bay, multi-user NAS environments, and this listing supplies it as a case of ten identical drives.

Construction and ownership details lean toward the long haul. Purpose-built for NAS enclosures, the drive is designed to run with little to no noise and vibration and to avoid the lags or downtime that can come from using the wrong drive in a busy array. The integrated IronWolf Health Management system reports drive condition to a compatible NAS, and Seagate rates the drive at 1M hours MTBF. The package also folds in a three-year limited warranty and three years of Rescue Data Recovery Services, so recovery is an option if a drive does fail. Buying ten at once is the practical route for anyone standing up or expanding an array who wants every bay filled with the same model.
