SanDisk Launches 2.5-Inch Solid State Drive to Replace Hard Disks in Mainstream Notebook Computers

    Expanding Its SSD Line, SanDisk Brings Durable, High-Performance Storage
to the Entire Range of Portable PCs

    MILPITAS, CALIF., March 13 /CNW/ - SanDisk(R) Corporation (NASDAQ:   SNDK)
today broadened its solid state drive (SSD) product line for the portable
computer market with the introduction of a 32-gigabyte (GB)(1), 2.5-inch
Serial ATA (SATA) interface model, compatible with most mainstream notebook
designs. Coming just two months after SanDisk introduced a 1.8-inch SSD for
ultraportable notebooks, the 2.5-inch SSD is now available to PC manufacturers
as a drop-in replacement for hard disk drives.

    "The SanDisk 2.5-inch SSD brings the extreme durability, outstanding
performance and low power consumption of solid-state flash memory to the
entire notebook computer market," said Amos Marom, vice president and general
manager of the Computing Systems division at SanDisk. "As SanDisk continues to
drive innovation in flash memory, the per-gigabyte price of SSD storage will
come down and SSD capacity will go up. PC manufacturers and consumers will
find it easier and easier to move away from rotating hard disks to the
superior experience of SSDs."

    The vast majority of notebook computers manufactured today use 2.5-inch
hard disk drives. The SanDisk 2.5-inch SSD fits in the same internal slot as
2.5-inch hard disks, so notebook manufacturers can switch to the SanDisk SSD
without altering their hardware designs.

    The key benefits of SanDisk SSDs for computer manufacturers and their
customers are:

    --  Reliability. SanDisk SSDs deliver 2 million hours mean time between
failures (MTBF)(2), approximately six times more than notebook hard disks.
With no moving parts, SanDisk SSDs are also much less likely to fail when a
notebook computer is dropped or exposed to extreme temperatures.

    --  Performance. In notebook computers, data moves to and from an SSD
more than 100 times faster than data moving to and from a hard disk. SanDisk
SSDs offer a sustained read rate of 67 megabytes (MB) per second(3) and a
random read rate of 7,000 inputs/outputs per second (IOPS) for a 512-byte
transfer(4). As a result, notebooks equipped with a 2.5-inch SanDisk SSD can
boot Microsoft(R) Windows(R) Vista(TM) Enterprise in as little as 30
seconds(5) and access files at an average speed of 0.11 milliseconds(6). A
notebook using a hard disk requires an average 48 seconds to boot and an
average 17 milliseconds to access files.

    --  Power efficiency. SanDisk SSDs have minimal power requirements, with
savings rated at over 50 percent compared with a hard disk drive -- 0.9 watts
during active operation versus 1.9 watts(7). This is particularly important in
extending battery life for road warriors, enabling them to remain productive
while in transit.

    --  Cool and quiet. Because SanDisk SSDs don't need a motor, bearings or
a moving head mechanism, they generate much less heat than hard disk drives.
SanDisk SSDs are also completely silent, while hard disk drives always make at
least some noise during read and write operations.

    "There are several reasons computer users and manufacturers should
consider SSDs as prices become more affordable," said Joseph Unsworth,
Principal Research Analyst for flash memory at the Gartner research firm. "For
example, Gartner research shows hard disk failure is tied for first place with
motherboard failure as the leading cause of overall hardware failure in
notebooks, with each accounting for 25 to 45 percent of the total(8). The
higher reliability of SSDs lowers total cost of ownership, and could be a
driver for adoption of SSDs. This is part of the explanation of why Gartner
projects global consumption of SSDs in consumer and business notebooks to leap
from about 4 million units in 2007 to 32 million units in 2010(9)."

    The 32GB, 2.5-inch SanDisk SSD is available now to computer
manufacturers, with initial pricing of $350 USD for large volume orders.
SanDisk SSDs will be demonstrated at the CeBIT show in Hannover, Germany, from
March 15 to 21, 2007, in Hall 23, Stand B28, and will be featured on March 16
during the PressExpoUSA @ CeBIT 2007 event.
