Worked great for a week or so. Installed CloudReady (Chromium OS, like Chrome OS on Chromebooks) and Ubuntu (Linux OS) and both were very fast. When computer wouldn't boot properly, I turned the computer off by holding down the laptop power button until it shut off. After that it wouldn't boot and the computer won't detect this SSD drive anymore. Tried to reinstall numerous OSs but none would even detect the SSD. I even tried it in 2 different laptops but neither would detect the SSD. Should I return for exchange or is there a way to repair the disk?
