Seagate Introduces Improved Hybrid Drive

June 20, 2010

Analysis of:Seagate Momentus XT hybrid SSD boots into a new dimension | media.seagate.com

Seagate has introduced the Momentus XT Solid State Hybrid Drive offering a flash storage buffer to accelerate access to data from the HDD. Seagate and other HDD companies tried to introduce such hybrid HDDs back in 2007 but they failed to catch on due to issues with Microsoft Windows support. The Momentus XT does not depend upon Windows to support it, adaptive memory software detects frequently accessed data and moves it onto the faster flash memory, removing less frequently accessed content.

Many fast ways to connect computers

April 23, 2010

Light peak is a high speed optical cable that will initially be able to delivery 10 Gbps data rates but may scale to 100 Gbps within 10 years. Light peak is expected to be used to connect peripheral devices, workstations, displays, disk drives, docking stations and other devices. There are rumors that Light Peak will be available to PC manufacturers later this year and ship in 2011. It should be possible to run USB 3.0 on Light Peak as well as other protocols.

Strong first quarter for HDD companies

April 22, 2010

Seagate and WD gave their CQ1 2010 quarterly reports and HGST provided some guidance on their quarter. Seagate reported revenue of $3.05 B on 50.3 M units and Western Digital reported revenue of $2.6 B on 51.5 M units. HGST reported revenue of $1.46 B on somewhat more than 26 M units. For the first time WD units shipped exceeded Seagate. The rest of 2010 appears upbeat for HDD companies as demand will likely exceed manufacturing capacity resulting in good ASPs and record revenues for the HDD companies.

Does it make sense to combine HDDs and flash memory?

March 24, 2010

Analysis of:Comeback of Seagate in Hybrid HDD? | www.storagenewsletter.com

In 2007 Seagate and Samsung announced the introduction of hybrid HDDs combining a NAND flash memory cache on the HDD circuit board. Although initially supported by Microsoft, the product failed due to higher priced hybrid HDDs vs. non-hybrid HDDs as well as lack of OS support for dual memory systems. There is a rumor that Seagate is looking at re-introducing hybrid HDDs with less expensive flash, TRIM command support and a controller geared for controlling use of flash and HDD storage

Isilon joins ranks of enterprise flash memory users

February 22, 2010

Analysis of:Isilon Turbo-Charges Scale-out NAS With Solid State Drives | www.infostor.com

Isilon is using STEC solid state drives for metadata serving in their next generation of NAS systems. This will speed up metadata-intensive namespace operations and assist server virtualization, electronic design and financial analysis. The actual data is stored on SAS or SATA HDDs but metadata access is through the SSDs. Combining SSDs for metadata with HDDs for the data provides higher performance data operations while maintaining the low costs of HDD storage systems

January 28, 2010

Analysis of:Kingston Coming With 30 GB ‘Boot’ SSD for $80 | www.tomshardware.com

Kingston announced that it is offering a 30 GB SSD for holding operating system and applications. This drive would be used to let a computer boot more quickly and load and move between applications more quickly. These products can be used with a HDD where user files and content are stored. A hybrid storage approach could make a lot of sense for faster booting computers without giving up the storage capacity of today’s HDDs.

What could help blu-ray discs become widespread in the US?

January 28, 2010

Analysis of:Blu-ray Beginning to Gain on DVD Player Market | mesalliance.org

Blu-ray discs won the HD format war a little more than a year ago, just in time for the economic downturn and reduced consumer spending. Blu-ray discs and players have become popular in Japan but not as popular in the US due to the costs of drives and discs and the success of upconverted DVD players. In the holiday season of 2009 there were reports of less than $100 Blu-ray players and some Blu-ray titles selling for about $10, lower prices should drive additional demand.
