Toshiba plans to invest about 60 billion yen, or $380 million, to double HDD production capacity in the Philippines by fiscal 2027, seeking to expand its share of global storage capacity from just over 10% to 30% over the medium term. The company plans drives with up to 40% more capacity and is pursuing 65-terabyte-class products by 2030, eventually targeting 100-terabyte-class models. Western Digital shares fell 11.07% to $411.33 on Friday, while Seagate also declined, as investors assessed the prospect of greater competition in enterprise storage. Analysts at Citi and LYNX Equity Strategies said Toshiba's expansion is unlikely to materially relieve tight global supply because production also depends on outside component suppliers and may chiefly address Japanese domestic demand. Western Digital reported fiscal fourth-quarter revenue of $3.75 billion, up 44% year on year, with cloud customers accounting for 89% of sales.
