Super fast. The overall performance is stunning after this upgrade. The only CON is that Rapid Mode doesn't yet work with Windows 10. It is still an extreme improvement over my 7200 RPM drive I replaced.
Easy to install and the performance, over an Hdd, is truly amazing. The drive it self is light weight yet solid. The Samsung software makes the installation seamless and the SSD monitoring is a breeze. I bought this drive because of its high ratings and reviews and so far it has lived up to them both.
Pros: Lightweight, great performance upgrade, easy intallation
