IBM HUC101890CSS200 900GB 10000RPM 12Gbps SAS internal hard drive

900GB 10K SAS drive for transactional workloads

This 2.5-inch internal hard drive delivers 900GB of capacity on a 12Gbps SAS interface. It is built for servers and storage arrays that need consistent throughput for databases, virtualisation hosts or email servers. The 10,000RPM spindle provides low latency for random I/O patterns typical of OLTP applications. It ships with a Lenovo system storage caddy for direct installation in compatible bays.

Capacity and headroom for mixed read or write loads

At 900GB the drive holds several hundred virtual machines or a medium-sized SQL dataset with room for snapshots. Sequential transfers benefit from the 12Gbps link, while the 10K RPM spindle sustains IOPS for concurrent threads. Workloads that exceed the physical spindle speed or require sub-millisecond latency for every request will hit the mechanical limit. Archival or cold data is better placed on larger, slower media to preserve the performance tier.

2.5-inch SAS build with included caddy

The small-form-factor chassis fits dense 2.5-inch drive bays in rackmount enclosures and blade chassis. A single SAS port handles both data and power through the backplane, reducing cable count. The supplied Lenovo caddy aligns with the V3700 V2 tray positions, so the drive seats securely without adapters. Vibration tolerance is rated for multi-drive cages, and the one-year manufacturer warranty covers the sealed mechanism.
