Lenovo 00MJ149 1.2TB 2.5" 10000RPM SAS-2 HDD

The Lenovo 00MJ149 is a 2.5 inch hard drive that supplies 1.2 TB of enterprise-class storage for servers and dedicated storage arrays. Built for demanding data centers, it spins at 10,000 rpm to keep response times low and throughput steady during heavy workloads.

A SAS-2 interface running at 6 Gb per second pairs with 64 MB of onboard cache to move data quickly. Virtual machines start sooner, database queries finish faster, and file shares stay responsive even when many users access them at once. Because the drive follows the 2.5 inch form factor, it slides directly into standard Lenovo server bays without additional brackets.

The capacity and rotational speed make the Lenovo 00MJ149 well suited to virtualization clusters, transactional databases, and mixed read-write workloads that run in rack-mounted environments. Administrators who need consistent input-output performance but must also watch rack space will value the compact housing, which allows more drives per chassis and increases overall IOPS potential.

The model is qualified for Lenovo System X and Storage V3700 platforms, so firmware, monitoring tools, and hot-swap carriers recognize it immediately. This validation simplifies deployment, reduces compatibility concerns, and supports long-term reliability in production settings.

• 1.2 TB capacity and 10,000 rpm spindle speed help maintain low latency
