SemiAnalysis — ruthenium, a hard-drive input, went from about $560 an ounce in early 2025 to near $1,950 in September

A cost input the nearline-storage story rarely prices: SemiAnalysis puts ruthenium at about $560 an ounce in early 2025 against dealer quotes near $1,950 in September, and calls it a key hard-drive material. Only the thread's opening post is in hand, so how much ruthenium a drive uses, and whether Seagate and Western Digital can pass the cost through in a tight market, still has to be read in the remaining four posts before treating it as a margin risk.
