Cost Eective and Light Weight

Purchase just the right amount of storage, 8GB,
16GB, 32GB, or 64GB*, packed inside a memory
device that is up to one-tenth the weight of the

1.8” HDD3. SanDisk’s field proven, cost-eective,
multi-level cell (MLC) NAND flash technology,
enables competitive pricing for these low cost
portable devices.

Fast

Your users will see the dierence from the
moment they power up their netbooks with
SanDisk pSSD modular SSD: faster machine
operation.

SanDisk pSSD boots fast and keeps working
at high speed, without the need to spin up
into action or to seek files like a conventional
HDD. SanDisk’s modular SSD achieves
high sustained random write performance
translating to 9,000 vRPM.

In addition, nCache™ SanDisk’s large
non volatile write cache provides a burst
performance of x5 the sustained random write,
allowing the users to enjoy an enhanced user
experience, without the typical stuttering found
in first generation SSD modules. pSSD empties
its cache during idle time, and since the cache is
non-volatile there is no risk of data loss to
the user.

Rugged and Reliable

Design strong and solid netbooks that
withstand the wear-and-tear of people on
the go, and operate soundlessly even in
environments where noise is a nuisance,
such as bedrooms.

With no moving parts, SanDisk pSSD modular
SSD is far more reliable than a HDD. Backed
by its patented flash management technology,
SanDisk brings high data integrity to its
modular flash device. Dynamic bad block
management, dynamic and static wear-leveling,
and robust error detection and correction code
(EDC/ECC) ensure data reliability.

Power Ecient

Extend battery life of netbooks by using SanDisk
pSSD modular SSD, and see a significant power
savings over using a rotating HDD, a critical
matter for netbook users on the go.

Designing with SanDisk

SanDisk has a 20 year legacy of innovating
industries by creating powerful new
technologies that have revolutionized the world
of portable computing.

Our storage devices empower thousands of
products by hundreds of global manufacturers
to deliver better end-user experiences. SanDisk
is a trusted leader in flash memory with many
NAND flash technology patents.

2. B ased on TestMetrix benchmark perform ance may be l ower depe nding on h ost device . 1 megaby te (MB) = 1 mill ion bytes .

3. Weight of second generation pSSD varies from 5 .3 gram s – 9 grams, d epending upon c apacit y. This is comp ared to the
