WUH722020BL5204 Overview<\/p>\n
The Western Digital Ultrastar DC HC560 20TB (Model: WUH722020BL5204) is a high-performance, enterprise-grade hard drive designed to meet the massive storage demands of modern data centers and cloud service providers. As one of the first drives to introduce Western Digital\u2019s groundbreaking OptiNAND technology, the HC560 redefines storage efficiency by integrating an iNAND UFS Embedded Flash Drive (EFD) with traditional spinning media. This innovative architecture enhances drive resiliency, improves write performance, and allows for higher areal density. Engineered for 24\/7 reliability in mission-critical environments, the HC560 is the perfect solution for hyperscale cloud storage, massive scale-out systems, and high-density computing clusters where maximizing capacity per rack is essential.<\/p>\n","protected":false},"featured_media":8010,"comment_status":"closed","ping_status":"open","template":"","meta":{"_acf_changed":false},"product_brand":[266],"product_cat":[433,449],"product_tag":[1286,550,1282,1089,1287],"class_list":["post-8009","product","type-product","status-publish","has-post-thumbnail","product_brand-western-digital","product_cat-storage-devices-storage-devices","product_cat-western-digital-storage-devices-storage-devices-storage-devices","product_tag-20tb","product_tag-3-5-inch","product_tag-512mb","product_tag-hard-drive","product_tag-sas-12gb-s","first","instock","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
