Blocks & Files Experts Compare WD and Seagate Revenue per Exabyte

A recent study by Blocks & Files examines how revenues and GAAP net profits per exabyte shipped to the market by Western Digital and Seagate Technology have evolved over the last seven quarters. The report highlights a constantly changing competitive dynamic between these two data storage leaders. 📊

Seagate Starts Strong but Its Advantage Fades

At the beginning of the analyzed period, Seagate achieved significantly higher revenue per exabyte than Western Digital. The initial difference was approximately 2.6 million dollars. However, the data show that Seagate's revenue per unit of capacity began to decline steadily quarter after quarter. This suggests that the company has had to lower its prices per exabyte marketed.

Key Points of the Initial Trend:
  • Seagate starts with revenue of 16.58 million dollars per exabyte.
  • Western Digital begins at 13.9 million dollars for the same unit.
  • The gap favoring Seagate narrows progressively over time.
In the hard disk business, earning more per byte doesn't always mean filling your pocket more at the end of the day.

The Gap Closes, but Profitability Tells Another Story

In the most recent quarter included in the analysis, the difference in revenue per exabyte between the two companies has narrowed considerably. Seagate's advantage is reduced to less than one million dollars. Despite its revenue per capacity decreasing and approaching WD's, the GAAP data reveal a crucial fact: Seagate manages to maintain a higher net profitability margin than Western Digital throughout the entire period studied.

Conclusions from the Competitive Analysis:
  • Seagate's revenue advantage per unit shrinks from 2.6M to about 870,000 dollars.
  • Both companies converge in their revenue per exabyte shipped.
  • Seagate demonstrates greater efficiency in converting that revenue into net profits.

A Strategic Competition in the HDD Sector

The Blocks & Files report underscores the complex reality of the hard disk market. While revenue per capacity equalizes, a company's ability to generate more profits with similar figures becomes the key differentiating factor. This reflects different strategies in costs, operational efficiency, or product mix. The landscape suggests intense rivalry where final profitability, and not just the price per gigabyte, defines the leader. 🏆
