are optimized for performance so you can spend more time experiencing the
things you love most.
Inspiring performance and capacity
Available in capacities up to 6TB, WD Black 3.5-inch PC Hard Drives deliver rapid transfer
speeds and read rates of your files with impressive DRAM cache sizes of up to 256MB
on high capacity models. Western Digital’s Dynamic Cache Technology makes real-
time optimizations in the allocation of cache between reads and writes to maximize
performance based on the user’s specific workload. Combine a WD Black hard drive
with a Western Digital SSD for a dual drive configuration that allows the operating
system and critical applications to be stored on the SSD for further-enhanced system
performance.
For Creative Professionals
When it comes to storing and editing your digital portfolio, look no further than WD Black
3.5-inch PC Hard Drives. Use the WD Black hard drives for storing your large multimedia
files including photos, videos, and games to get the best combination of performance and
capacity.
For Gamers
WD Black 3.5-inch PC Hard Drives are the perfect storage solutions for gaming machines,
providing large capacities to store today’s high-resolution games and their associated
downloadable content (DLC) with increased cache sizes that reduce load times. System
performance can be boosted even further when combined with a Western Digital SSD.
2TB and greater models of WD Black hard drives also include StableTrac™ Technology
for more accurate data tracking and to help reduce any impact from vibrations caused
by other gaming hardware.
Increased Reliability
StableTrac Technology (on 2TB and greater models) enables more accurate tracking that
improves the performance of both read and write operations. By securing the motor
shaft, the impacts of system-induced vibrations from other components are reduced,
leading to enhanced reliability.
An Industry Leading Warranty
WD Black 3.5-inch PC Hard Drives are tested under more strenuous conditions over a
longer period when compared to our standard hard drives. This comprehensive testing
ensures an overall quality benchmark for a stable, high performance storage solution
backed by an industry leading 5-year limited warranty.

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and
one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used
for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per sec-
ond (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective
maximum SATA 3 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATA-IO
organization as of the date of this specification sheet. Visit www.sata-io.org for details.
