Crucial® M550 Solid State Drive

Do more. Faster. Longer.

A breakthrough in innovation, the Crucial® M550 SSD is over 20 times faster than a typical hard drive and consumes significantly less power. It enables your computer to boot up almost immediately, load files and programs almost instantly, accelerate demanding applications, and manage power more efficiently so your battery lasts longer. Backed by the most advanced feature set available - Native Write Acceleration, RAIN (Redundant Array of Independant NAND) technology, Adaptive Thermal Protection, hardware-based encryption, and our exclusive data integrity algorithm - the Crucial M550 delivers a complete performance gain that's measured by far more than just specs.

Consistently fast speeds. No exceptions.

Every manufacturer has ideas about how to deliver better performance. Some use file compression schemes, but those don't help video, audio, or graphic files that are already compressed. Some steal system memory to improve a slow drive. The Crucial M550 treats all files the same, regardless of whether they're compressed or uncompressed, so the specs we advertise are the same ones you'll see in real world use: true 550 MB/s sequential reads across all file types.

Save on power costs and enjoy longer battery life.

Run your system longer than ever before - and use less power. Based on published specs, a common laptop hard drive uses 2.5 watts of power on an average workload, compared to 0.15 watts on the Crucial M550 (which is up to 94% more energy efficient). In everyday terms, this means significantly more battery life and substantial savings on power costs.

Secure and protect your data - with no loss in performance.

You probably save lots of sensitive and personal information on your computer - encrypt it and keep it safe. As a self-encrypting drive, the Crucial M550 incorporates the highest level of hardware encryption into the controller, allowing the drive to operate at full speed without the performance loss associated with software-based encryption. The Crucial M550 is one of the only drives on the market to meet the rigorous requirements of TCG Opal 2.0, IEEE-1667, and Microsoft® eDrive®.

Micron® quality - a higher level of reliability.

As a brand of Micron, one of the largest flash storage manufacturers in the world, the Crucial M550 is backed by the same quality and innovation that has produced some of the world's most advanced memory and storage technologies. With over a thousand hours of pre-release validation testing and hundreds of SSD qualification tests, the Crucial M550 has been thoroughly tried, tested, and proven for the most demanding applications.
