Lenovo 4XB0G45722 300GB 10000 RPM SAS 2.5" laptop hard drive

Lenovo ThinkServer Gen 5 300 GB SAS drive

This 2.5-inch enterprise hard drive delivers 300 GB of storage on a SAS 6Gb/s interface. It spins at 10000 RPM to serve high-throughput server workloads such as databases and transactional applications. The drive is built for ThinkServer Gen 5 platforms and carries Lenovo validation for reliability. It targets IT teams that need fast, hot-swappable capacity in a compact form factor.

Hot-swap tray and SAS connector

A single SAS 6Gb/s port handles both data and power through the backplane, so the drive slides into a hot-swap bay without cable routing. The 2.5-inch carrier fits standard enterprise drive cages and allows replacement while the server stays online. Lenovo’s robust design and strict validation aim to reduce failure rates under continuous operation. The connector layout matches Gen 5 drive bays for tool-less installation.

Verify SAS backplane and bay count

Before ordering, confirm that your server chassis provides 2.5-inch hot-swap bays wired for SAS 6Gb/s signalling. The drive requires a compatible backplane or RAID controller that supports the SAS protocol and hot-plug capability. Check the system’s drive-count limit and available slots to ensure the new unit can be added without exceeding the enclosure capacity. Ensure firmware on the controller is current for full compatibility.
