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
On October 23 along with the highly-anticipated announcement of the iPad 4, Apple rolled out new Macintosh computers that for the first time in an Apple product pairs an SSD with a conventional HDD to get the best combination of capacity, speed, and price. The company calls this its Fusion Drive, not to be confused with Fusion-io’s highly-regarded products.
The SSD Guy did not attend the announcement, and there is little on the Apple website. I contacted Apple, and they don’t have very much detail to share at this time. This is important to note, since Continue reading
At the Intel Developer Forum Intel showed Seagate‘s updated Momentus XT Hybrid Solid State Drive in operation. The new drive is only 7mm thick, significantly thinner than the 9.5mm Momentus XT that the company has been shipping for the past 2 years.
This is significant because the 13mm target thickness of the Ultrabook platform is extremely difficult to achieve using a 9.5mm drive, yet the performance specification of the Ultrabook requires the use of NAND flash, either in the form of a full-blown SSD, an HDD with an additional cache SSD, or a hybrid drive. Of the three choices, Continue reading
Nikkei Electronics published an article on May 22 detailing a May 17 briefing by Toshiba president Norio Sasaki. Mr. Sasaki told of the company’s plans to introduce a hybrid HDD (HHDD) in September of this year that is aimed at the Ultrabook market. 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
During Western Digital’s April 26 earnings call (as transcribed by Seeking Alpha) CEO John Coyne disclosed that Western Digital has ongoing development efforts in hybrid HDDs: “In addition, we are continuing investments in strategic growth areas such as SSD, hybrid drives and the digital home.”
It’s encouraging to see a second entrant into this market.
After a false start that was synchronized with the ill-fated launch of Microsoft’s Vista operating system, hybrid HDDs have been a technology that is rarely ever mentioned. So far the hybrid HDD has been the sole domain of Seagate Technology with Continue reading
Seagate has just announced an upgrade to the company’s Momentus XT hybrid HDD family. Seagate announced in August that the company had already shipped over one million units of its first generation Momentus XT since its May 2010 introduction.
For those unaware of what a hybrid HDD is, the short answer is that it’s a way to get HDD capacities and SSD speeds at a price marginally higher than that of an HDD. Continue reading
On Tuesday, November 1, Seagate announced improvements to its flagship Barracuda line of 3.5″ HDDs for the desktop.
- The 5,900 RPM Barracuda Green will be discontinued in February
- The 7,200 RPM Barracuda XT will be re-named the Barracuda (without the XT designation, which indicates a “top of the line” speed)
- A new Barracuda XT line will be introduced at a later date and it will incorporate the hybrid design Seagate pioneered in the popular Momentus XT.
Capacities will range from 250GB-3TB. Continue reading
