Given features like these in any hard disk, there would not be mixed thoughts on the performance of the product.This hard disk works almost 4 times faster than the 5400 RPM HDD you might have used before. This product is particularly suited to newer laptop models which support HD videos, pictures and graphic interfaces. It will allow you to store your data as it is, without compromising on quality. A useful feature is the in-built SATA DVD writer, making this product a multi-use device.
