Pros:The brand to buy if you like replacing your operating system, programs and data periodically.
Cons:Too expensive to replace annually.
Hard drive failed prior to the expiration of the one year warranty. Because we were traveling I did not call Western Digital until three weeks after the one year period expired. My fault. Customer service not sympathetic. They said "too bad" and offered to sell me another hard drive. Since this was the second Western Digital hard drive I have owned that failed I declined. I will not own another Western Digital product.
