The WD Ultrastar DC HC550 delivers 18TB in a standard 3.5-inch drive over a fast 12Gb\/s SAS interface, so servers and arrays hold more data in the same rack space with less power and cost per terabyte.

Its 12Gb\/s SAS interface suits dual-port enterprise controllers and multi-drive arrays, while CMR (conventional magnetic recording) keeps write performance consistent for RAID rebuilds and mixed workloads, unlike SMR drives. A 7200 RPM spindle and 512MB cache keep throughput high, and helium-sealed construction runs cooler and draws less power per terabyte across a dense enclosure.\u003c\/p\u003e\n\u003ch3\u003eHighlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e18TB capacity:\u003c\/strong\u003e high-density storage in a standard 3.5-inch form factor for lower cost per terabyte.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12Gb\/s SAS interface:\u003c\/strong\u003e fast, reliable enterprise connectivity for servers and RAID controllers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7200 RPM with 512MB cache:\u003c\/strong\u003e consistent throughput for demanding data center workloads.\u003c\/li\u003e\n\u003cli\u003eCMR recording and 512e sector format for RAID compatibility and predictable performance.\u003c\/li\u003e\n\u003cli\u003eBacked by a 5-year limited warranty for data center reliability.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Western Digital Corporation","offers":[{"title":"Default Title","offer_id":53610851991736,"sku":"0F38353","price":1033.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/9110\/4952\/files\/1064240247.jpg?v=1782036037","url":"https:\/\/islandelectricalsupply.com\/products\/wd-ultrastar-dc-hc550-wuh721818al5204-18tb-sas-hard-drive","provider":"Island Electrical Supply","version":"1.0","type":"link"}
