This Amazon package uses MPN ST4000VXZ16; the underlying drive model is ST4000VX016 and the host connection is SATA 6Gb\/s.\u003c\/p\u003e\u003cp\u003eFor ST4000VX016, Seagate specifies 5400 RPM, a 256MB cache and CMR recording, with a maximum sustained transfer rate of up to 180MB\/s. The SATA 6Gb\/s figure refers to interface bandwidth and is not the sustained read or write speed of the mechanical drive.\u003c\/p\u003e\u003cp\u003eSkyHawk is designed for continuous surveillance recording and supports up to 64 HD camera streams. ImagePerfect firmware is intended to support consistent video workloads, while the stated workload rating is up to 180TB per year. These features reflect its DVR\/NVR role rather than general desktop or NAS positioning.\u003c\/p\u003e\u003cp\u003eInstallation requires a compatible SATA controller, standard drive power and a free 3.5-inch internal bay. The capacity, RPM, cache, CMR technology and transfer rate here are tied to ST4000VX016\/ST4000VXZ16 and are not copied from another SkyHawk capacity. For a recorder with an approved-drive list, verify the exact model before adding the disk to an existing surveillance system.\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSeagate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSkyHawk \/ ST4000VX016\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMPN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eST4000VXZ16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCapacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4TB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDrive Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eInternal HDD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eForm Factor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.5-inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInterface\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSATA 6Gb\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRotational Speed\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5400 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCache\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e256MB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRecording Technology\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCMR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIntended Use\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSurveillance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaximum Sustained Transfer Rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to 180MB\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWorkload Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e180TB\/year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Seagate","offers":[{"title":"Default Title","offer_id":58312815739263,"sku":"B0B1JPYH2Z","price":189.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/8581\/5935\/files\/71W0Rtw4_AL.jpg?v=1788102123","url":"https:\/\/ssd247.co.uk\/products\/seagate-4tb-skyhawk-internal-surveillance-drive-sata-6-gb-s-st4000vxz16","provider":"SSD247","version":"1.0","type":"link"}
