WUS5EC1C1ESP7Y3 Overview<\/p>\n
The Western Digital Ultrastar DC SN655 61.44\u202fTB is a U.3 2.5\u2011inch PCIe\u202f4.0\u202f\u00d74 NVMe solid\u2011state drive engineered for read\u2011intensive data\u2011center and server workloads. It uses NVMe\u202f1.4 and PCIe\u202fGen4 technology paired with Western Digital BiCS5 3D TLC NAND flash, delivering a balanced mix of throughput and endurance suitable for cloud services, large\u2011scale analytics, distributed databases, and AI\/ML applications in enterprise environments. The drive offers high sequential performance with read speeds up to about 4,300\u202fMB\/s and write speeds up to around 3,150\u202fMB\/s, along with robust random I\/O performance (approximately 890,000\u202fIOPS for random reads) that helps ensure responsive access to large datasets under heavy concurrency.<\/p>\n","protected":false},"featured_media":9989,"comment_status":"closed","ping_status":"open","template":"","meta":{"_acf_changed":false},"product_brand":[266],"product_cat":[433,449],"product_tag":[1257,1807,1606,1822,1775,1214,356,1199,1201],"class_list":["post-9988","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-nvme","product_tag-3150-mb-s","product_tag-4300-mb-s","product_tag-61-44-tb","product_tag-form-factor","product_tag-nand","product_tag-pci-express","product_tag-solid-state-drive","product_tag-tlc","first","instock","shipping-taxable","product-type-simple"],"acf":[],"yoast_head":"\n
