The Toshiba N300 10TB (HDWG71AEZSTAU) is a 3.5-inch SATA hard drive built for NAS systems, desktop RAID arrays and personal cloud storage that run around the clock. It spins at 7,200RPM with a 512MB buffer and Toshiba's Dynamic Cache Technology, delivering up to 281MB/s sustained transfer, and uses conventional magnetic recording (CMR) for consistent write behaviour during RAID rebuilds. Rotational vibration and shock sensors keep it stable in enclosures of up to eight bays, and it is rated for a 180TB-per-year workload in 24/7 operation with a 1-million-hour MTTF. That makes it a good fit for larger home-lab and small-business NAS arrays where you want more space per bay, whether you run Synology, QNAP or TrueNAS. Typical power draw is 9.07W operating and 5.74W at idle. This is the retail kit, with the drive supplied in a Toshiba box, and Toshiba's datasheet lists a 3-year limited warranty (confirm the local supplier's warranty terms when ordering).
