Next Generation SSD From a
Proven Enterprise Storage Player
HGST leverages decades of proven enterprise storage
expertise in Serial Attached SCSI (SAS) design reliability,
firmware, customer qualification and system integration
to the new Ultrastar SSD400S.B solid-state drive (SSD)
family. The synergistic relationship between HGST’s new
throughput-enhancing SSDs and traditional HDDs provides
cost effective, end-to-end enterprise-class storage solutions,
delivering reliability, compatibility, capacity, cost and system
performance. This combination makes HGST a leading HDD/
SSD provider with the experience and technology needed to
meet escalating reliability, endurance, and performance in
the most demanding enterprise environments.
The Ultrastar SSD400S.B family combines enterprise-grade
SLC NAND flash memory, advanced endurance management
firmware and power loss data management techniques to
extend reliability, endurance, and sustained performance
over the life of the SSD. The Ultrastar SSD400S.B family
achieves an extraordinary 0.44% annual failure rate (AFR)
or two million hour mean-time-between-failure (MTBF). The
400GB capacity Ultrastar SSD endures up to 35 petabytes
(PB) of random writes over the life of the drive – the
equivalent of writing 19.2 terabytes (TB) per day for five years.
For complete end-to-end data protection and reliability,
the Ultrastar SSD400S.B family incorporates the T10 Data
Integrity Field (DIF) standard, extended error correction code
(ECC), Exclusive-OR (XOR) parity to protect against flash die
failure, parity-checked internal data paths without an external
write cache, and an exclusive power loss data management
feature that does not require supercapacitors. The Ultrastar
SSD400S.B family is backed by a five year limited warranty, or
the maximum petabytes (PB) written (based on capacity).
Applications/Environments
•
Ultra-high performance tier-0 enterprise storage
•
Enterprise-class servers and High Performance
Computing
•
Space and/or power constrained environments
•
Online Transaction Processing (OLTP)
•
Video pre/post production
•
Financial, eCommerce
•

Extreme Endurance and
Performance for the Enterprise
The new Ultrastar SSD400S.B delivers high sequential
throughput, up to 536MB/s read and 502MB/s write (6Gb
SAS). The Ultrastar SSD400S.B also delivers up to 57,500
read and 25,500 write IOPS, reaching speeds 100 times
faster than HDDs, allowing rapid access to “hot” enterprise
data for improved productivity and operational efficiency.
Since less SSDs are required to achieve the same HDD IOPS
performance, the new Ultrastar SSD400S.B family offers sig-
nificant value in terms of IOPS per Watt, while reducing total
cost of ownership (TCO) through low power consumption,
efficient cooling and reduced space requirements.
HGST Quality and Service
HGST’s Ultrastar SSD400S.B family extends the company’s
long-standing tradition of performance and reliability leader-
ship. A balanced combination of new and proven technolo-
gies enables high reliability and availability to customer data.
HGST drives are backed by an array of technical support
and services, which may include customer and integration
assistance. HGST is dedicated to providing a complete
portfolio of HDD/SSD solutions to satisfy today’s
monumental computing needs.

One gigabyte (GB) is equal to one billion bytes when referring to hard drive and SSD
capacity. One terabyte (TB) equals 1,000GB, and one petabyte (PB) equals 1,000TB.
Accessible capacity will vary depending on the operating environment and formatting.
MTBF target is based on a sample population and is estimated by statistical measurements
and acceleration algorithms under nominal operating conditions. MTBF ratings are not
intended to predict an individual drive’s reliability. MTBF does not constitute a warranty.
