WD6400AAKS-40H2B1) delivers 7200 RPM performance with SATA 3Gb\/s interface connectivity and 16MB cache buffer. The 640GB capacity supports moderate-scale storage and archival applications typical of legacy enterprise systems, departmental file servers, and secondary storage arrays. 3.5-inch form factor fits standard drive bays in tower and rackmount enclosures. SATA 3Gb\/s throughput suits sequential and mixed workloads where sustained I\/O matters more than latency-sensitive random access. Compatible with most systems built 2008–2012 requiring conventional mechanical storage; often paired with legacy RAID controllers and external enclosures.\u003c\/p\u003e\u003cp\u003eTested and guaranteed; available via quote.\u003c\/p\u003e","brand":"Westren Digital","offers":[{"title":"New","offer_id":52794476921045,"sku":"WD6400AAKS-40H2B1","price":172.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/4930\/9653\/files\/wd6400aaks-40h2b1__12355.1513198529.jpg?v=1765049311","url":"https:\/\/g5networkgroup.com\/products\/wd6400aaks-40h2b1-new","provider":"G5 Network Group","version":"1.0","type":"link"}
