Western Digital Ultrastar DC SN650 15.36TB 2.5" U.3 NVMe G4 1 DWPD 15mm SE WUS5EA1A1ESP5E1 / 0TS2434

High Capacity NVMe™ SSD and
Disaggregated Storage Architecture
As cloud and scale-out data centers have become more and more
disaggregated, storage has been able to scale independently from compute,
giving businesses elasticity during peak demands while avoiding data silos and
improving TCO.
Disaggregating storage is ideal for cloud service providers. It offers a variety of
storage services that combine to deliver a higher quality-of-service, improved
performance consistency, and higher storage utilization.
For scale-out data center customers, disaggregated storage provides
managed service providers to efficiently increase capacity for modern
applications processing large unstructured datasets.
As workloads grow to petabytes, high capacity, cost-optimized storage SSDs
have an increasingly important role to play. The Ultrastar DC SN650 NVMe SSD
can reduce those time-to-insights.
PCIe ® Gen 4.0
The new Ultrastar DC SN650 NVMe SSD includes the next generation
Western Digital ® controller, PCIe Gen 4.0 interface, and Western Digital BiCS5
TLC 3D NAND.
BiCS5 TLC 3D NAND, with higher bit density per mm 2 , is the next generation
of 3D NAND driving higher capacities, up to 15.36TB1 . With the latest PCIe
Generation 4.0, the Ultrastar DC SN650 enables performance at scale for
increasingly larger application workloads. Designed and built for the standard
2.5” SSD storage infrastructure, it includes support for U.2
and U.3 backplanes.
Emerging Workloads
The Ultrastar DC SN650 NVMe SSD is optimized for cloud and scale-out
workloads requiring higher QoS consistency, and better storage utilization for
block, object or file storage.
Emerging workloads for big data, artificial intelligence, and machine learning
are increasing in size and complexity. They are typically stored across
distributed, tiered, or disaggregated architectures. The Ultrastar DC SN650
NVMe SSD is optimized for moving these large datasets fast and servicing
multiple hosts with performance consistency, making them ideal for scaling
capacity and maximizing GB/watt for these emerging larger workloads.
Safeguarding data
The Ultrastar DC SN650 NVMe SSD ensures that if you lose power, you don’t
lose your data. The drive comes with Power Loss Protection that keeps your
data safe should you experience a sudden and unexpected interruption in
power supply. And if you ever need to decommission the drive,
Secure Erase provides you with entire drive erase options.
Reliability
The Ultrastar DC SN650 NVMe SSD is built for reliability, incorporating
enterprise-class features such as power-loss protection, 2M hour reliability
(projected) and 1 DW/D. And if that weren’t enough, it also comes with a
five-year limited warranty.
