I was about to throw my laptop Lenovo, four years old, which was slow and unreliable. But this Samsung drive gave her a new life. It is much faster, highly reliable, and its battery lasts for 5 hours instead of 3. Installation was easy, even for me as almost zero technology and the supplied software to copy the old drive worked perfectly . But I was a little annoyed at having to invest 14 euros in a SATA cable that I will use maybe once in my life. Samsung should provide a cable with the disc. But I'm really pleased with the product. I regret not having an SSD installed long ago.
