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.
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” enter-
prise 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 signifi-
cant value in terms of IOPS per Watt, while reducing total cost of ownership (TCO) through low
power consumption, efficient cooling and reduced space requirements.
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).
