Continuous Innovation for HDDs
Ultrastar hard drive innovations include
the first commercial implementation of Energy-Assisted Magnetic Recording (EAMR) technology
the industry’s first Triple Stage Actuator (TSA)
the sixth generation product with HelioSeal technology
Shingled Magnetic Recording (SMR)
enable the industry’s highest capacities to lower data centre TCO
Western Digital Ultrastar DC HC550
Ultrastar DC HC550 integrates a suite of technologies on a 9-disk platform to create a new class of HDDs. The 18TB capacity is achieved through a combination of technologies that improve areal density, all while working with technologies that improve performance and reduce power consumption.
Provides 29% more capacity in the same form factor as a 14TB HDD
Enables data centers to lower CapEx by reducing supporting hardware costs
CMR technology works with all capacity enterprise applications & environments
Western Digital Ultrastar DC HC650
Ultrastar DC HC650 is HDD with host-managed SMR enables the highest capacity HDDs for data centres. Media tracks are overlapped (or ‘shingled’) with adjacent tracks, resulting in greater tracks per inch (TPI) to achieve increased areal density.
Integration of industry-first EAMR & TSA technologies with HelioSeal® and host-managed SMR to deliver 11% more capacity than 18TB CMR drives
Purpose-built for sequential write applications
Estimated MTBF up to 2.5 million hours
Ultrastar HDDs Applications
Cloud & Hyperscale storage
Bulk storage using object storage solutions like Ceph™ and OpenStack® Swift
Primary and secondary storage for Apache Hadoop® for Big Data Analytics
Big Data or Bulk Storage
Social media
Online Back-up and Replication
Compliance, Audits and Regulatory Records
The Ultrastar DC HC550 18TB CMR HDD and Ultrastar DC HC650 20TB SMR HDD are delivering industry-leading capacity for the data centre through a combination of new and proven technologies.
Western Digital Ultrastar DC SN640
Ultrastar DC SN640 is NVMe SSD is a mainstream NVMe™ SSD targeting broad deployment as boot, caching, or primary storage in data centre IT and cloud environments. The DC SN640 is optimized to deliver the highest performance and consistent QoS read latency when running randomly mixed workloads typically generated by enterprise applications such as virtualization, OLTP, NoSQL, web servers, file servers, and mail servers.
Boosts data centre performance and responsiveness as direct-attached, distributed storage or in large scale cloud deployments.
Includes 3D TLC NAND NVMe 1.3c controller and incorporates enterprise reliability features, such as power-loss protection or end-to-end data path protection
0.8 DW/D SKU features tunable endurance giving the flexibility to configure endurance and performance
Ultrastar SSDs Applications
Boot, cache or storage
Software Defined Storage
File, Block and Object Storage applications
Hyper-converged Infrastructure (HCI)
Virtualization
JBOD platforms
Western Digital Ultrastar Data60 Hybrid Storage and Ultrastar Data102 Hybrid Storage
are a key element of next-generation disaggregated storage and Software-Defined Storage
(SDS) systems. The platforms represent two variants of 4U JBODs
that can be connected via HBA or HW RAID controller to any server
to expand the total available capacity by 60 to 102 3.5″ drives.

ArcticFlow is a specially designed disk cooling system where the entire system is divided into two separate parts (front and rear).
IsoVibe reduces vibrations on individual HDDs and fans to increase overall reliability.
Zoning, where each I/O module has 6 × SFF 8644 and each of these connectors can be assigned any number of HDD positions.
JBOF platforms
JBOF variant OpenFlex Data24 extends high performance NVMe flash to shared storage. By doing so, it provides low-latency sharing of NVMe SSD drives via high-performance Ethernet connectivity, which provides similar performance to locally connected NVMe SSD drives. RapidFlex™ technology then allows up to six guests to connect without using a switch. This storage platform can also be used as a separate storage source in disaggregated infrastructures.
