It spins at 7200 RPM, has a 512MB cache, and records with CMR. A helium-filled case keeps power draw and weight down.\u003c\/p\u003e\n\u003cp\u003eSeagate rates it for 550TB of workload a year and a 2.5 million hour MTBF. It idles at about 5.7 W, so twelve of these drives idle near 69 W.\u003c\/p\u003e\n\u003ch2\u003eWhat the Exos X22 is made for\u003c\/h2\u003e\n\u003cp\u003eSeagate lists cloud data centers, high-density RAID, Hadoop and Ceph clusters, backup, and video surveillance among its target uses.
