Absolutely Terrible Customer Service

First drive was lost, then second drive took forever to arrive. The drive itself is good but the customer service is international some where in India probably and it's HORRENDOUS, unless you have a coupon get it from Bestbuy or Amazon.

Western Digital Gold drives are the best!

Western Digital Gold drives are what you buy when you expect 24/7 service. All the Gold drives in my environment have been running non-stop 365 days a year without failure!
