SanDisk Ultrastar DC SN655 61.44TB U.3 15mm 4300MB/s PCIe Gen4 NVMe 1.4b SSD

The SanDisk 0TS2510 is an enterprise solid state drive in the Western Digital Ultrastar DC SN655 family. It provides 61.44TB of NVMe storage inside a 15 mm U.3 enclosure, giving data-center teams an immediate way to raise capacity without adding more servers.

Using PCIe Gen4 and the NVMe 1.4b specification, the drive reaches up to 4300 MB/s for sequential reads and 3150 MB/s for sequential writes. Random performance climbs to 890 K IOPS for reads and 29 K IOPS for writes, a mix that fits analytics pipelines, content delivery networks, and other read-heavy applications.

Built-in reliability features help protect data and keep workloads online. Dual port connectivity enables transparent failover if a path goes down, while power-loss protection works to safeguard in-flight transactions. The drive carries a projected 2.5 million-hour MTBF and is rated for one drive write per day. When it is time to retire or redeploy, Instant Secure Erase lets administrators sanitize the media quickly and confidently.

Because the 0TS2510 works with both U.2 and U.3 backplanes, it drops into existing infrastructure with minimal effort. Cloud platforms, AI and machine-learning clusters, large relational databases, and virtualized environments can all benefit from its combination of high capacity, strong throughput, and consistent latency.
