Seagate Upgrades Hybrids, Phases Out 7,200RPM HDDs

Seagate's New SSHD FamilySeagate made two important statements on two successive days – March 4 and 5: First, the company disclosed plans to phase out its 7,200 RPM 2.5″ notebook HDDs, and second, Seagate announced a new line of Momentus XT hybrid hard drives, which the company calls: “Solid State Hybrid Drives” or “SSHDs.”

The article notes that Toshiba is the only company that produces both NAND flash and HDDs, now that Samsung sold its HDD business to Seagate.

The article also says that Toshiba: “aims to become one of the top three companies in the HDD market in terms of market share.” The SSD Guy is forced to wonder at this comment, since there are only three HDD manufacturers in existence today: Toshiba, Western Digital, and Seagate.

The Seagate Momentus XT, the only Continue reading
