Review: Great drive at a great price with a great, known brand. - Western Digital makes quality hard drives, period. The performance is always good, they always seem to work and the cost is better than buying from the computer manufacturer. I purchased this for my college freshman's new laptop. You couldn't get anything more than a 512G hard drive and that wasn't going to be enough. Installing was easy after we figured out how to open the laptop housing. The WD drive fit as expected and worked perfectly after we made a direct backup of the original drive. Compatibility was never an issue and 2tb of capacity was exactly what we needed.
