Toshiba’s Storage Products Business Unit of Toshiba America Electronic
Components, Inc., a committed technology leader, today announced customer
shipments of its first Hybrid Drive, the MQ01ABDH series. The series provides
the ideal combination of performance found in solid state disks (SSDs) and the
capacity and cost-effectiveness of hard disk drives (HDDs) with capacities up
to 1 terabyte^2 (TB).


Developed to enhance the PC user experience, the new 2.5-inch 9.5mm high SATA
Hybrid Drive series features “self-learning” caching algorithms that learn the
system user’s data access patterns to optimize performance. The self-learning
caching algorithms also manage which user data is stored to the NAND Flash for
quick response to the near future access from the host, as well as how the
data in the NAND Flash is updated based on intelligent access pattern
learning.

“Hybrid Drives represent a significant innovative technology for Toshiba in
combining the high-performance features of NAND Flash, with the key HDD
attributes of large capacity and cost-effective data storage,” said Joel
Hagberg, vice president of marketing at Toshiba’s Storage Products Business
Unit. “As the only storage company which designs and manufactures HDDs as well
as NAND flash, Toshiba is in a unique position to capitalize on these benefits
because the expertise on how these technologies function resides within
Toshiba.”

Toshiba’s MQ01ABDH series transforms the user experience with extreme
responsiveness and breakthrough performance enabling faster system boot-up
times and data access. Available in 1TB and 750GB^1 capacities, the MQ01ABDH
100 and MQ01ABDH 075 drives are ideally suited for ultrathin and
standard-sized notebooks, gaming PCs, all-in-one and slimline desktops and
other digital computing applications where a no-compromise approach to system
performance and storage capacity is desired.

The MQ01ABDH series will be featured in various notebook PCs, with the first
systems shipping in time for the holiday season.
