Western Digital makes hard disk drives for cloud data centers, computers, and personal storage.
Western Digital designs and makes hard disk drives (HDDs), which store data on spinning magnetic disks. Cloud data centers and enterprise storage companies use its high-capacity drives to keep large amounts of data; computer makers use its drives in desktop and notebook computers. The company also sells external drives for personal storage through retail and distribution partners.

Three ratings, each a percentile against the 72 companies we cover in Semiconductors. Deliberately kept apart rather than blended into one score — cheap, rising and well-run are three different facts, and a single number would hide which one is which.
Near the top of its industry
The most recent month is left out on purpose: returns tend to persist over 7–12 months and the newest one tends to reverse. This describes what the price has done, and says nothing about what it will do.
Middle of its industry
Yields, so higher means cheaper — a loss-making company ranks last instead of dropping out. Cheap is not the same as good: a high yield is often a price that fell for a reason. All five measures available.
