As
hard

capacities
increase,
the
power
required
to
run
those
drives
increases
as
well.
WD
Caviar
Green
drives
make
it
possible
for
energy-conscious
customers
to
build
systems
with
higher
capacities
and
the
right
balance
of
system
performance,
ensured
reliability,
and
energy
conservation.
Reduced
power
consumption
-
WD
has
reduced
power
consumption
by
up
to
40
percent
compared
to
standard
desktop
drives
with
the
combination
of
WD's
IntelliSeek™,
NoTouch™,
and
IntelliPower™
technologies.
Helps
enable
eco-friendly
PCs
-
WD
Caviar
Green
drives
yield
an
average
drive
power
savings
of
4-5
watts
over
standard
desktop
drives
making
it
possible
for
our
energy-conscious
customers
to
build
systems
with
higher
capacities
and
the
right
balance
of
system
performance,
ensured
reliability,
and
energy
conservation.
This
power
savings
equates
to
reducing
CO2
emission
by
up
to
13.8
kilograms
per
drive
per
year
-
the
equivalent
of
taking
a
car
off
the
road
for
3
days
each
year*.
By
using
environmentally-conscious
PCs
with
our
WD
Caviar
Green
drives
on
board,
large
organizations
with
many
desktop
computers
can
minimize
their
carbon
footprint
and
save
real
money
on
electricity
costs.
*Assumes
that
a
car
produces
1.60
CO2
pounds
per
Kwatt/hours/year.
Calculation
of
automobile
emissions
depends
on
the
car's
g/km
emission
levels
and
km/year
of
driving.
Cool
and
quiet
-
GreenPower™
technology
yields
lower
operating
temperatures
for
increased
reliability
and
low
acoustics
for
ultra-quiet
PCs
and
external
drives.
Perfect
for
external
drives
-
External
drive
manufacturers
can
eliminate
the
need
for
a
fan
in
a
high-capacity
product
with
a
WD
Caviar
Green
drive,
the
coolest
and
quietest
in
its
class.
IntelliPower
-
A
fine-tuned
balance
of
spin
speed,
transfer
rate
and
caching
algorithms
designed
to
deliver
both
significant
power
savings
and
solid
performance.
IntelliSeek
-
Calculates
optimum
seek
speeds
to
lower
power
consumption,
noise,
and
vibration.
