WUH722020BLE6L4 Overview<\/p>\n
The Western Digital Ultrastar DC HC560 20TB (Model: WUH722020BLE6L4) is a high-capacity enterprise hard drive specifically engineered to address the rigorous storage demands of cloud service providers and large-scale data centers. As a flagship model in the Ultrastar DC series, the HC560 features Western Digital\u2019s pioneering OptiNAND\u2122 technology, which integrates an iNAND Universal Flash Storage (UFS) Embedded Flash Drive (EFD) within the HDD. This hybrid architecture optimizes internal data management, increases drive resiliency, and allows for higher areal density without sacrificing performance. Designed for 24\/7 reliability, this drive is the ideal solution for high-density storage servers where maximizing Terabytes per rack and lowering Total Cost of Ownership (TCO) are primary objectives.<\/p>\n","protected":false},"featured_media":8008,"comment_status":"closed","ping_status":"open","template":"","meta":{"_acf_changed":false},"product_brand":[266],"product_cat":[433,449],"product_tag":[1286,550,1282,551,1089,1249],"class_list":["post-8007","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-7200rpm","product_tag-hard-drive","product_tag-sata-6gb-s","first","instock","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
