Western Digital WD Red Pro 18TB NAS Hard Drive | 7200RPM SATA3 512MB Cache CMR 24x7 5-Year Warranty

Your NAS runs around the clock, and a desktop drive will buckle under that load long before you notice. The WD Red Pro 18TB is built for exactly that job — tested with multi-bay NAS systems, rated for up to 24 bays, and backed by a 5-year warranty so you're not chasing a replacement at 7am on a Tuesday. CMR recording keeps sustained writes steady, and NASware 3.0 firmware handles the RAID chatter so your array stays in sync. Ships from our Australian warehouse once your order lands
