Western Digital is a major maker of hard disk drives and data storage systems, supplying cloud, enterprise, and consumer markets.
Supermicro hired ex-Western Digital CFO Mark Long as finance chief, nearly two years after promising to replace David Weigand. He inherits a co-founder's indictment in an alleged $2.5 billion chip-smuggling case and a grand jury subpoena on internal controls.
Reality
Sandisk's NAS 800, an endurance-tuned WD Black SN8100 rated for up to 14PB of writes, costs 45% to 65% more than that drive, Tom's Hardware found. The extra money buys about one full drive write a day for five years, so it pays off only in a NAS or workstation that writes that much.
Reality
Toshiba has shipped the first nearline hard drives from its expanded Laguna plant in the Philippines and aims to nearly double its capacity by fiscal 2027. Storage buyers planning for that year gain a new source to weigh, but orders due sooner still depend on existing supply.
Reality
Seagate is bidding against Toshiba for TDK's HDD head unit, the only independent head supplier, in a deal Bloomberg values at several billion dollars. Either winner would end that independence and could gain more say over what every drive maker pays for heads.
Reality
Western Digital and Seagate each fell 10.2% after Nikkei Asia reported Toshiba will spend $400 million to double its AI hard-drive capacity in fiscal 2027. The bull case now turns on timing, because Toshiba's extra drives reach the price talks only when hyperscalers negotiate 2028 terms.

Toshiba is spending about 60 billion yen to double its AI data-center hard-drive capacity by March 2028, its first major HDD investment in about five years. Its target of a 30% share of the market by storage capacity, roughly triple today's, depends on denser drives as well as new lines.

The KOSPI closed at 6,909.91 on the 11th, back below 7,000 but still up 3.33% for the week, and the memory names that led the advance fell again in New York on a day Brent dropped 2.81%.

A Seeking Alpha initiation rates Sandisk a Buy at $2,160 after fiscal 2026 revenue nearly tripled and non-GAAP gross margin reached 84.6%. The multiyear minimum-price agreements are the part that changes how the earnings should be underwritten.
Reality
The $31 billion is contingent on Tokyo funding about a third of it, and the Kitakami fab that absorbs 36% of the package does not run until the fiscal year beginning April 2029, so the firm portion is smaller than the headline.

Micron, Sandisk, Seagate and Western Digital ran 500% to 900% and more since the start of 2025. The recent reversal is the first real market test of the thesis behind it.
