I will now turn the call over President and Chief Executive Officer John Coyne. John Coyne Good afternoon and thank you for joining us today. Fiscal 2010 was another highly profitable growth year for WD. Ever increasing demand for cost effective and high capacity storage continues to provide opportunity for substantial growth and consistent value creation over an extended term when addressed with an effective business model. With a relentless focus on customer needs, quality, low cost and high asset efficiency, WD has become solidly and increasingly profitable throughout the last decade. Over the last five years, WD has profitably grown revenue at a compound annual rate of 22%. In this same period, we have grown operating income at a compound rate of 50% per annum. For fiscal year 2010, we grew revenue 32% to $9.8 billion. We increased operating income by 194% year-on-year. The hard drive demand growth story continues to be driven by the proliferation of multiple devices and applications that are resulting in the generation, utilization and storage either locally or in the cloud of massive amounts of digital content on low cost high capacity hard drives. We believe that the industry's growth trajectory will continue over the foreseeable future creating significant additional opportunity for WD with its well-honed business model and expanding product set to continue to generate growth on a sustained and profitable basis.
This growth opportunity has been created in large part by our ability to continually drive down average cost per gigabyte leading to attractive price points but have driven mass market adoption of devices incorporating hard drives. At the same time, we have gradually expanded gross margins while growing revenues by continuously increasing efficiencies and reducing costs.Our assessment in late April of a June quarter time in the range of 157 million to 162 million proved overly optimistic. Actual demand for hard drives in the quarter was about 156 million units, down 4% sequentially but up 16% from the year ago period. The major factors leading to the lower time were weakness in Europe, destocking by OEM customers and a shift in OEM ordering patterns to take advantage of lower cost sea versus air freight. In hindsight, this expanded the March quarter at the expense of the June quarter. Given the change in the demand during the June quarter, WD and others in the industry responded quickly to adjusted bill times, resulting in quarter ending inventory modestly increased but at manageable levels. Chip inventory increased from seven to 10 days, while component distribution inventories increased slightly but remained at the midpoint of the normal four to six-week range including in transit. Taking these market dynamics into account, we were pleased to deliver one of the strongest fiscal fourth quarter performances in company history. While market dynamics in the June quarter will tamper short-term growth rates and affect price levels in the September quarter, we believe that the second half of the calendar year and calendar year 2011 will continue to present substantial growth opportunities and rewards for hard drive industry participants with effective business models and compelling product offerings. WD continues to generate substantial free cash flow while continuing to reinvest significantly in our business, both in expanding and enhancing our product offerings and in improving our operations.
