It uses conventional magnetic recording (CMR), so heavy random writes and RAID rebuilds behave properly, and it has rotational vibration sensors to hold performance steady in a crowded chassis. Seagate rates it for an unlimited number of bays and 550TB of data a year. On compatible NAS systems, IronWolf Health Management surfaces drive health in the NAS software before problems become failures.\u003c\/p\u003e\n\n\u003ch3\u003eBigger drives, longer rebuilds\u003c\/h3\u003e\n\u003cp\u003eAt 20TB, a four-bay NAS in RAID 5 gives you about 60TB usable, which is a lot of storage for the bay count. The trade-off is rebuild time: replacing a failed 20TB drive takes many hours even at 285MB\/s, so RAID 6 or SHR-2 is worth considering on larger arrays. It's a 7200 RPM drive at 20 dBA idle and 26 dBA seeking, so a NAS full of them is audible in a quiet room. If you only need a few terabytes for a home media server, the standard IronWolf costs less and runs cooler.\u003c\/p\u003e\n\n\u003ch3\u003eFEATURES:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAgileArray firmware with dual-plane balancing and time-limited error recovery for RAID\u003c\/li\u003e\n\u003cli\u003eCMR recording for consistent multi-user performance\u003c\/li\u003e\n\u003cli\u003eRotational vibration sensors for stable performance in multi-bay enclosures\u003c\/li\u003e\n\u003cli\u003eIronWolf Health Management on compatible NAS systems\u003c\/li\u003e\n\u003cli\u003e3 years of Rescue Data Recovery Services (not available in all countries)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSPECIFICATIONS:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: Seagate IronWolf Pro 20TB (ST20000NT001)\u003c\/li\u003e\n\u003cli\u003eCapacity: 20TB\u003c\/li\u003e\n\u003cli\u003eForm factor: 3.5\"\u003c\/li\u003e\n\u003cli\u003eInterface: SATA 6Gb\/s (6.0 \/ 3.0 \/ 1.5 Gb\/s)\u003c\/li\u003e\n\u003cli\u003eRecording technology: CMR\u003c\/li\u003e\n\u003cli\u003eDrive design: Helium\u003c\/li\u003e\n\u003cli\u003eSpindle speed: 7200 RPM\u003c\/li\u003e\n\u003cli\u003eCache: 256MB\u003c\/li\u003e\n\u003cli\u003eSector size: 512e\u003c\/li\u003e\n\u003cli\u003eMax sustained transfer rate (OD): 285MB\/s\u003c\/li\u003e\n\u003cli\u003eDrive bays supported: Unlimited\u003c\/li\u003e\n\u003cli\u003eWorkload rate limit: 550TB\/year\u003c\/li\u003e\n\u003cli\u003eMTBF: 2,500,000 hours\u003c\/li\u003e\n\u003cli\u003ePower-on hours: 8,760 per year\u003c\/li\u003e\n\u003cli\u003eNonrecoverable read errors: 1 per 10E15 bits read\u003c\/li\u003e\n\u003cli\u003eRotational vibration (10 to 1500Hz): 12.5 rad\/s\u003c\/li\u003e\n\u003cli\u003eStartup current (12V, typical): 2.0A\u003c\/li\u003e\n\u003cli\u003eAverage operating power: 7.7W\u003c\/li\u003e\n\u003cli\u003eIdle power (average): 5.7W\u003c\/li\u003e\n\u003cli\u003eStandby \/ sleep power: 1.2W\u003c\/li\u003e\n\u003cli\u003eOperating temperature: 0°C ambient to 65°C drive reported\u003c\/li\u003e\n\u003cli\u003eAcoustics (idle \/ seek): 20 \/ 26 dBA\u003c\/li\u003e\n\u003cli\u003eShock (operating, 2ms read\/write): 40 \/ 40 Gs\u003c\/li\u003e\n\u003cli\u003eShock (non-operating, 1ms and 2ms): 200 Gs\u003c\/li\u003e\n\u003cli\u003eDimensions: 26.11 x 101.85 x 146.99mm\u003c\/li\u003e\n\u003cli\u003eWeight: 690g\u003c\/li\u003e\n\u003cli\u003eRescue Data Recovery Services: 3 years\u003c\/li\u003e\n\u003cli\u003eWarranty: 5 Year Limited\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWHAT'S IN THE BOX:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Seagate IronWolf Pro 20TB 3.5\" hard drive\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Seagate?\u003c\/h3\u003e\n\u003cp\u003eSeagate has made hard drives since 1979, and IronWolf Pro is its NAS line for business and professional users, with compatibility testing by major NAS brands.
