I installed this in a Lenovo T440p in less than a minute as a boot drive. It's fast, and functional as a boot drive. I was pleased with it.
Next, I installed it as an image storage drive for my W540. So far, it's proven to be reliable, fast and durable! Re-imaging ids a snap with Macrium Reflect, and the 240gb Super Boot 2!

I liked it so well, I purchased the 480gb version, and installed that in my second W540. I love the 480gb version as well. Reliable, and fast. Been recommending the SuperBoot2, to all my friends!
