Product Features
Superior performance for highend computing
For high-end computing 
applications like gaming, HD media 
playback, or creative software, 
WD Blue solid state drives have 
the speed you need for the 
performance you want. Tiered 
caching technology utilizing 
SLC (single-level cell) and TLC 
flash technology enables 
sequential read speeds of up to 
545MB/s and sequential write 
speeds of up to 525MB/s, allowing 
for fast system boot up, quick 
application response, and rapid 
transfer speeds.
Leading-edge reliability
With no moving parts, a solid state 
drive is designed to help protect 
against data loss if a drive is 
accidentally bumped or dropped. 
And with 1.75M hours MTTF (mean 
time to failure) and an endurance 
rating of up to 400 TBW (terabytes 
written), WD Blue SSDs can help 
protect data for years to come. 
WD Blue solid state drives also 
use several leading errorcorrection technologies to help 
protect against data loss and 
provide lasting reliability.
Maximized multitasking
WD Blue solid state drives are 
optimized for multitasking and can 
easily run several resource-heavy 
applications simultaneously. Run 
a background virus scan while 
watching a 4K video and checking 
your email.
Broad compatibility
Every WD Blue SSD goes through 
extensive compatibility and 
reliability testing to ensure it meets 
the highest standards of the WD 
brand. With a certification from the 
WD Functional Integrity Testing 
Labs (FIT Labs), every WD Blue SSD 
is verified for compatibility with a 
wide range of desktop and laptop 
computers.
Free WD SSD Dashboard
The downloadable WD SSD 
Dashboard provides a suite of tools 
so you’re always able to check on 
the health of your solid state drive. 
Available for free, this WD SSD 
Dashboard helps you track things 
like disk model, firmware version, 
S.M.A.R.T. attributes, or simply find 
out how much space you have left 
on your WD Blue SSD.
3-year limited warranty
Every WD Blue SSD comes with a 
3-year limited warranty, so you can 
be confident of your storage when 
you upgrade or replace any of your 
drives.
Applications

 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 second (MB/s) = one million bytes per second, and gigabit per second 
(Gb/s) = one billion bits per second. Effective maximum SATA 6 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.
4
 Performance is based on the CrystalDiskMark benchmark using a 1000MB LBA range on Gigabyte GA-Z77X-UD5H desktop with Intel Z77 chipset, Intel i7–3770 3.4GHz, 8M, Ivy Bridge, Windows 8 64-bit SP1 using 
Intel iRST version 11.7.0.1013, secondary drive, C-state off. Performance may vary based on host device. 1 MB = 1,000,000 bytes. IOPS = input/output operations per second.
5
 TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity.
6
 Measured using the MobileMark™ 2012 benchmark with DIPM (Device Initiated Power Management) enabled.
7
 MTTF = Mean Time To Failure based on internal testing using Telcordia stress part testing.
