WD elements Internal Hard disk drive is very light and easy to carry .The western digital is a ahead of any other brands in hard disk drive.I bought a WD Elements 1042 500GB before 4 year.it is very slim and provide high speed transfer work. it is also available in a variety of color and.the best part of WD is its quality. So quality is very important and trust this brand for quality. smartware software that comes with this drive provided password and encryption features to protect your date .You can take backup of your important data and documents and if Hard disk itself gets corrupt. Thought its performance is little disappointing, it is acceptable till your data is safe.Performance issue comes while reading and writing huge size files.For small size file performance is great. Smartware also perform continuous incremental backup of your data files. There is perfect value of your money.Recommended to all’You can purchase now. Thank you
