Seagate 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.”
Are these two announcements related? Well, The SSD Guy thinks they are!
Higher-RPM HDDs help to accelerate disk accesses by a small percentage while a hybrid can boost speeds significantly. According to Seagate, Continue reading
Now that we have seen announcements of hybrid drives from Western Digital and Seagate, Toshiba arrives with a formal announcement of the product that was on display at last month’s Flash Memory Summit. Two 2.5″ Toshiba hybrid drives are starting to sample at 750GB and 1TB capacities. Both have 8GB NAND caches, 6Gb/s SATA 3 interfaces, and 5,400RPM spindle speeds. They are both built using 32nm SLC NAND, Toshiba’s “generation before last” technology, preceding the 24nm and 19nm nodes shipping in high volume today.
More importantly, both are 9.5mm in height, a thickness that renders them difficult to incorporate into the 18mm maximum thickness of the smaller Ultrabooks – a notebook form factor that Intel is heavily promoting.

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
