As part of an alignment between Seagate and Samsung, Seagate will take over Samsung’s storage department. Looks like an answer to western digital acquiring hitachi storage, which took place a couple of months ago.

This means there are three companies left manufacturing mechanical hdd. These are Western Digital, Seagate and Toshiba. While Seagate and Western Digital have a large share of the market, Toshiba has small and is not considered a “threat” to both Seagate and Western Digital.
