For a Plex library, a family archive, or camera footage, the NE000 does the job. Four of these drives in RAID 5 give about 60TB usable. In RAID 6 you get 40TB.\u003c\/p\u003e\n\u003cp\u003eRotational vibration sensors help it hold speed in a crowded enclosure. AgileArray firmware adds dual-plane balancing and time-limited error recovery for RAID. Seagate lists 20 dBA at idle and 26 dBA while seeking. IronWolf Health Management works on supported NAS systems.\u003c\/p\u003e\n\u003cp\u003eSeagate rates the NE000 for systems of up to 24 bays. Most home and office NAS units have two to eight, so that limit rarely matters.
