The Western Digital Ultrastar DC SN655 61.44 TB SSD (model 0TS2510) is a high-capacity enterprise-grade NVMe solid-state drive designed for read-intensive data-center and server storage workloads. It uses a PCIe 4.0 ×4 NVMe 1.4 interface in a U.3 2.5-inch (15 mm) form factor, making it compatible with hot-swappable enterprise drive bays and high-density storage systems. The drive delivers strong performance with up to around 4,300 MB/s sequential read and 3,150 MB/s sequential write speeds, and up to about 890,000 IOPS random reads, providing fast access to large datasets in demanding applications. Read-intensive classification with 1 Drive Write Per Day (1 DWPD) endurance makes it suitable for workloads where data reads dominate.
