Plus, our Dynamic Write Acceleration technology uses an adaptable pool of high-speed, single-level cell flash memory to generate blistering speeds throughout the drive’s long life.

Over 90x more energy efficient than a typical hard drive²

Extreme Energy Efficiency technology within the Crucial MX300 reduces the amount of active power usage that's consumed by the drive. The Crucial MX300 extends your laptop's battery life by using only 0.075W of power, compared to a typical hard drive which uses 6.8W.

Entrust your files to a drive that lasts

With an endurance rating of up to 220TB total bytes written, the Crucial MX300 is engineered with Micron® 3D NAND to deliver years of fast performance. The 3D NAND leverages larger NAND cells to improve performance and prolong endurance.

Protect your data with AES 256-bit hardware-based encryption, RAIN technology, Exclusive Data Defense technology, and the durability inherent in SSD design.

Keep your system cool

In addition to lower active power usage, Adaptive Thermal Protection technology dynamically adjusts storage component activity. This helps keep your system cool and minimizes the risk of damage caused by overheating.
