This exact SKU is identified by HDWT840UZSVA and uses a SATA 6Gb\/s interface.\u003c\/p\u003e\u003cp\u003eIt runs at 5400 RPM with 256MB of cache and SMR recording. The manufacturer lists a maximum sustained transfer rate of up to 184MB\/s. SATA 6Gb\/s is the interface bandwidth, not the sustained read or write speed of the disk.\u003c\/p\u003e\u003cp\u003eThe stated workload rating is 180TB\/year, a measure of annual data activity rather than capacity. Toshiba specifies HDWT840UZSVA as the 4TB bulk S300 model. It is designed for surveillance recording, supports up to 64 cameras and up to eight drive bays, and uses SMR recording with a 5400 RPM spindle and 256MB buffer.\u003c\/p\u003e\u003cp\u003eA SATA 6Gb\/s host connection and a free 3.5-inch drive bay are required. Capacity, cache and RPM, together with recording technology, in this listing are tied to this exact model and are not copied from another capacity in the same series. For NAS, RAID or surveillance use, the host system should support the exact drive model and required SATA connection. The 3.5-inch format is intended for systems with a matching internal bay, SATA data connection and standard drive power connector.\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eToshiba\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eS300 \/ HDWT840UZSVA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMPN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHDWT840UZSVA\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\u003eSMR\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 184MB\/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":"Toshiba","offers":[{"title":"Default Title","offer_id":57810837668223,"sku":"B0974Y9725","price":175.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/8581\/5935\/files\/615RVUyy4uL.jpg?v=1782115893","url":"https:\/\/ssd247.co.uk\/products\/toshiba-s300-4tb-internal-surveillance-hard-drive-3-5-sata-hdd-supports-up-to-64-hd-cameras-at-a-180tb-year-workload-hdwt840uzsva","provider":"SSD247","version":"1.0","type":"link"}
