Fueling Innovation
Design Flexibility
With future-ready, scalable NVMe architecture, the Western Digital
PC SN520 NVMe SSD offers a robust solution to fuel generations of innovative
IoT applications. Scalable NVMe offers a significant performance increase over
SATA SSDs while further optimizing low power consumption to the low level
of 2.5mW.
This NVMe SSD enables greater design flexibility for IoT and embedded
customers, who seek a cost effective, small form factor, reliable and rugged
storage device with low capacity points from 128GB to 512GB.
Robust Construction Suited for IoT
The Western Digital PC SN520 NVMe SSD, supporting PCIe Gen3 x2,
is designed for applications that have a limited number of PCIe lanes available
for storage, however, require both high performance and low power. Partners
that could benefit from NVMe technology include:
•
Commercial:
Interactive kiosks, ATMs and Point-of-Sales (POS), Multi-Functional
Printers (MFP) and industries that require high-volume transaction processing
•
Edge Equipment and IoT Gateway:
Such as network equipment, industrial
machinery, medical equipment, or embedded PC that need the high
capacities to capture the floor’s and sensors’ data and the high IOPS
to support the system’s data analytics
•
Media Content Delivery and Streaming:
In-flight entertainment systems,
train control and monitoring systems, data recorder and video surveillance
that require high capacity and reliability

As used for storage capacity, one gigabyte (GB) = one billion bytes and one terabyte (TB) = one trillion bytes.
Total accessible capacity varies depending on operating environment.
Test Conditions: Performance is based on the CrystalDiskMark 5.2.2 benchmark using a 1000MB LBA range ASUS
Z170A desktop with Intel® i7-6700K 4.0GHz, 8GB 2133MHz DDR4. Windows 10 Pro 64-bit using Microsoft StorNVMe
driver, secondary drive. Performance may vary based on host device. 1 MB = 1,000,000 bytes. IOPS = input/output
operations per second.
TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity.
Measured using MobileMark™ 2014 on HP EliteBook X360 1030 G2 with i7-7600U, 8GB RAM. Windows 10 Pro,
64-bit RS3 using Microsoft StorNVMe driver, primary drive.
Power measurements at 25°C.
MTTF = Mean Time To Failure based on internal testing using Telcordia stress part testing. MTTF is based on a sample
population and is estimated by statistical measurements and acceleration algorithms. MTTF does not predict an
individual drive’s reliability and does not constitute a warranty. (Telecordia SR-332, GB, 40°C)
Operational temperature as reported by device (composite temperature.)
Non-operational storage temperature does not guarantee data retention.
5 years or Max Endurance (TBW) limit, whichever occurs first. 5 year warranty in regions not recognizing “limited.”
