Lenovo 2.5-Inch 1.2TB 10K SAS Hot-Swap Enterprise Hard Drive

Data centers running Lenovo ThinkSystem or ThinkServer platforms often need a storage upgrade that balances capacity, speed, and reliability. The Lenovo 2.5-inch 1.2TB 10K SAS hot-swap hard drive steps in for exactly those scenarios—think database servers, virtualization hosts, or high-transaction applications where every millisecond counts. With a 10,000 RPM spindle speed and a 12Gbps SAS interface, it keeps up with demanding workloads while fitting neatly into standard 2.5-inch drive bays.
