This exact SKU is identified by WD221KFGX and uses a SATA 6Gb\/s interface.\u003c\/p\u003e\u003cp\u003eIt runs at 7200 RPM with 512MB of cache and CMR recording. 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 Up to 550TB\/year, a measure of annual data activity rather than capacity. WD Red Pro is designed for multi-bay NAS and RAID environments that run around the clock. The 22TB model combines CMR recording, a 7200 RPM spindle and a 512MB cache, with NASware firmware intended to support compatibility and controlled error recovery in NAS systems.\u003c\/p\u003e\u003cp\u003eA SATA 6Gb\/s host connection and a free 3.5-inch drive bay are required; NAS compatibility should be checked against the enclosure vendor. 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.\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWestern Digital\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWD Red Pro \/ WD221KFGX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMPN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWD221KFGX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCapacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e22TB\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\u003e7200 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCache\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e512MB\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\u003eNAS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWorkload Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to 550TB\/year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Western Digital","offers":[{"title":"Default Title","offer_id":58235477557631,"sku":"B0B5W1CQ8W","price":939.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/8581\/5935\/files\/61LfBBllx7L.jpg?v=1787232773","url":"https:\/\/ssd247.co.uk\/products\/wd-red-pro-22tb-nas-3-5-internal-hard-drive-7200-rpm-class-sata-6-gb-s-cmr-recording-technology-512mb-cache","provider":"SSD247","version":"1.0","type":"link"}
