Purpose-built for the demands of edge computing and
operating system boot drives

The Western Digital CL SN720 NVMe SSD for data centers provides high performance
for read-intensive workloads: content delivery, internet gaming, IoT, data analytics, and
operating system boot operations.

Available in capacity points from 256GB to 2TB, the Western Digital CL SN720 NVMe SSD
allows for storage flexibility based on data size requirements related to edge computing
and operating system operations.

LDPC error correction mechanisms provide enhanced reliability and help support a
five-year limited warranty. The Western Digital CL SN720 NVMe SSD operates with most
common data center operating systems, including Windows Server® 2012/2016 and
multiple versions of the enterprise Linux® operating systems.

The Western Digital CL SN720 NVMe SSD is a PCIe Gen3 x4 storage device offered in a
M.2 2280 form factor. In environments where data access speed is essential, the Western
Digital CL SN720 NVMe SSD delivers extreme per formance with sustained sequential read
and write speeds up to 3,400MB/s and 2,800MB/s respectively.

It is architected to help minimize the probability of data loss due to unexpected power
loss. To help address data security requirements, the Western Digital CL SN720 NVMe
SSD supports self-encrypting-drive (SED) capability, which is compliant with TCG OPAL

2.01 to help protect data from unauthorized access. The Western Digital CL SN720 NVMe
SSD also includes Instant Secure Erase (ISE) functionality to speed and simplify drive
redeployment and retirement.

Summary

The Western Digital CL SN720 NVMe SSD enables outstanding performance, optimal
endurance, and extended enterprise validation for Boot and Edge applications. With
capacities from 256GB to 2TB in an M.2 form factor, the Western Digital CL SN720 NVMe
SSD delivers a robust, reliable, and future-ready storage solution.
