3.5" HDD

The WD Red 3TB 3.5″ SATA HDD is a purpose-built, internal hard drive designed for 24/7 operation in NAS and RAID environments. It typically operates at 5400 RPM (or uses IntelliPower technology) and features Western Digital’s exclusive NASware firmware (e.g., NASware 3.0), which optimizes it for NAS systems by increasing compatibility, integration, reliability, and power efficiency. With a 3TB capacity, 64MB or 256MB cache, and a SATA 6 Gb/s interface, it’s a reliable, quiet, and cool-running solution for archiving, sharing, and backing up digital content.
