Operator
Good day, and thank you for standing by. Welcome to Western Digital's fiscal fourth quarter 2022 conference Call. [Operator instructions] I will now turn the call over to Mr. Peter Andrew, vice president, FP&A, and investor relations.
You may begin.
Peter Andrew -- Vice President, Investor Relations
Thank you, and good morning, everyone. Joining me today are David Goeckeler, chief executive officer; and Wissam Jabre, chief financial officer. Before we begin, let me remind everyone that today's discussion contains forward-looking statements, including product portfolio expectations, business plans and performance, demand and market trends, and financial outlook based on management's current assumptions and expectations and, as such, does include risks and uncertainties. We assume no obligation to update these statements.
Please refer to our most recent financial report on Form 10-K filed with the SEC for more information on the risks and uncertainties that could cause actual results to differ materially. We will also make references to non-GAAP financial measures today. Reconciliations between the non-GAAP and comparable GAAP financial measures are included in the press release and other materials that are being posted in the investor relations section of our website. With that, I'll now turn the call over to David for introductory remarks.
David Goeckeler -- Chief Executive Officer
Thank you, Peter. Good morning, everyone, and thanks for joining the call to discuss our fourth quarter and fiscal 2022 results. I'm pleased that the Western Digital team executed well and delivered solid results in light of the ongoing macro and geopolitical dynamics. We reported fourth quarter revenue of $4.5 billion, non-GAAP gross margin of 32%, and non-GAAP earnings per share of $1.78, all within the guidance ranges we provided in April.
Fiscal year 2022 revenue totaled $18.8 billion, and we reported non-GAAP earnings per share of $8.22. This compares to revenue of $16.9 billion and non-GAAP earnings per share of $4.55 in fiscal year 2021. We grew revenue 11%. And EPS increased 81%, demonstrating progress in unlocking the earnings potential of our business.
In addition to strong financial performance, fiscal year 2022 was a hallmark year for Western Digital from an innovation, product development, and execution perspective. In particular, we regained innovation leadership with the introduction of multiple products and technologies for the cloud. In May, we announced the 26-terabyte drive, leveraging our OptiNAND and UltraSMR technologies, as well as ePMR. Impressively, this means we've nearly doubled drive capacity relative to when I joined Western Digital just over two years ago.
