Analysts on average had forecasted revenue of $3.25 billion.

Adjusted profits topped $356 million, or $1.51 per share, down 20% from a year ago. Wall Street was looking for adjusted profits of $334.8 million.

The company said it sold 48.5 million hard-drive units, down from the 54.5 million units shipped in the March quarter.

Hard drives use spinning disks to store data, unlike the company’s growing line of solid-state drives, which use chips.

Western Digital’s disk drives go into computers, external storage devices, corporate networks and consumer electronics, such as laptops.

In the 12 months through the end of its fiscal year on June 30, the company posted sales of $14.6 billion, down 3.3%.

Adjusted profits hit $1.8 billion, down about 10%.

Western Digital shipped 228.7 million hard drives in the 12 months through June, down from 249.2 million in the same period a year earlier.
