Crucial MX300 275GB 3D NAND SATA 2.5" Internal SSD

The Crucial CT275MX300SSD1 is an internal 2.5 inch SATA solid state drive that brings high speed storage to desktops and laptops without the cost or complexity of a new system. Built with 3D NAND, it reaches sequential read speeds up to 530 MB/s and write speeds up to 500 MB/s, so operating systems load quickly, large files open almost immediately, and demanding applications feel more responsive.

With 275GB of capacity, the drive offers plenty of room for an operating system, everyday programs, and a library of photos, documents, or games. If you are upgrading an older computer, you will notice shorter boot times and smoother multitasking right away. Content creators can scrub through timelines and open project assets with less waiting, while gamers can move past loading screens and into the action sooner.

Energy efficiency is another advantage. The MX300 draws only 0.075 watts, which helps keep laptop batteries going longer and lowers power demands in small form factor desktops. The 7mm height allows it to slide into slim ultrabooks and mini PCs, yet an included 9.5mm spacer lets it fit standard drive bays as well.

Reliability is backed by an endurance rating of 220TB total bytes written and Adaptive Thermal Protection that monitors temperatures and adjusts performance to prevent overheating. Whether you spend hours editing photos, compiling code, or simply browsing the web, you can count on consistent performance over years of use.
