WUS5EC1C1ESP7Y4 Overview<\/p>\n
The Western Digital Ultrastar DC SN655 61.44TB NVMe SSD (part number WUS5EC1C1ESP7Y4) is an enterprise\u2011grade high\u2011capacity NVMe solid\u2011state drive engineered for demanding data\u2011center and server storage environments. It uses a PCIe\u202f4.0\u202f\u00d74 NVMe\u202f1.4 interface and a U.3 (15\u202fmm) form factor, fitting standard hot\u2011swappable enterprise drive bays. This SSD delivers up to ~4,300\u202fMB\/s sequential read and ~3,150\u202fMB\/s sequential write performance, along with strong random I\/O (around 890\u202fK IOPS read and ~29\u202fK IOPS write), enabling fast access to large data sets in read\u2011heavy workloads like cloud services, big data analytics, and large\u2011scale virtualization.<\/p>\n","protected":false},"featured_media":9987,"comment_status":"closed","ping_status":"open","template":"","meta":{"_acf_changed":false},"product_brand":[266],"product_cat":[433,449],"product_tag":[1257,1807,1606,1822,1775,1214,356,1260,1199,1201],"class_list":["post-9986","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-read-intensive","product_tag-solid-state-drive","product_tag-tlc","first","instock","shipping-taxable","product-type-simple"],"acf":[],"yoast_head":"\n
