Lenovo 900GB 10K 12Gbps SAS 2.5″ SFF Enterprise Hot-Swap Hard Drive

Overview

The Lenovo 00YK015 (associated with Retail/Option Part Number 7XB7A00026) is an enterprise-class, high-density 900 Gigabyte (GB) internal hard disk drive. Engineered specifically for late-generation Lenovo ThinkSystem servers, it combines a fast 10,000 RPM rotational spindle speed with a high-bandwidth 12 Gbps Serial Attached SCSI (SAS-3) interface.

This drive provides the ultra-low transactional latency and robust IOPS throughput required for multi-tenant virtualization, enterprise databases, and mission-critical cloud storage tiers. It comes mounted on Lenovo’s toolless, hot-swappable ThinkSystem G4HS (Generation 4 Hot-Swap) SFF drive carrier tray.

Performance & Reliability Metrics

Sustained Interface Transfer Rate: Up to 210 MB/s to 215 MB/s sequential read/write execution.
Dual-Port High Availability: Equipped with standard dual-port physical routing paths to support active failover, multipath I/O (MPIO), and link aggregation within modern high-availability SAN arrays and RAID nodes.
Mean Time Between Failures (MTBF): Rated at 2.0 million hours for high-stress, 24/7 continuous data center operational profiles.
Hot-Swap Carrier Integration: Pre-assembled onto the standard ThinkSystem SFF Caddy, featuring a heavy-duty locking lever and integrated optical light pipes for system backplane LED activity and status signaling.

Server Platform Compatibility

The 00YK015 / 7XB7A00026 drive assembly is engineered explicitly for Lenovo ThinkSystem (Intel Xeon Scalable / AMD EPYC based) server lines and is not backwards-compatible with legacy IBM System x (Gen3/G3HS) backplanes.
