Crucial BX500 120GB 2.5" SATA III Internal SSD

The Crucial CT120BX500SSD1 is a 2.5 inch internal solid state drive that replaces a traditional hard drive and immediately shortens boot times, file transfers, and program launches. It delivers 120GB of flash-based storage, which is plenty of room for an operating system, office applications, web browsers, and the documents you reach for every day.

Installation is straightforward. The drive slips into any laptop or desktop that accepts a 2.5 inch, 7 mm SATA bay and connects through the familiar SATA III 6 Gb/s interface. If you are upgrading an older system that still boots from a spinning hard drive, the switch can be completed with only a screwdriver and cloning software, often in less than an hour.

Performance is where the BX500 stands out. Sequential read speeds reach up to 540 MB/s, while write speeds top out at 500 MB/s, so the operating system loads briskly and large files move quickly. Everyday tasks—opening a browser, launching a game, or saving a large presentation—feel smoother because there is no mechanical delay.

Built with Micron 3D NAND, the drive is engineered for long-term reliability. It carries a 1.5 million-hour mean time to failure rating and a 40 TB total bytes written endurance figure, giving you confidence that it will hold up under regular, real-world workloads.

Because there are no moving parts, the BX500 runs silently and draws as little as 60 mW when active. That low power profile helps extend battery life in laptops and keeps desktop builds cooler and quieter.

This drive is a practical choice for students breathing new life into an old notebook, workspace PCs that need a cost-effective speed boost, or home users who want a reliable boot drive without spending a fortune. If you have a system with a compatible 2.5 inch SATA slot, the BX500 is an easy upgrade that you will notice every time you press the power button.
