Proven Enterprise Storage Experience
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 SSD400M 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.
Maximum Performance, Reliability and Endurance
The new Ultrastar SSD400M delivers high sequential throughput, up to 495MB/s read and
385MB/s write (6Gb SAS) in a compact 2.5-inch form factor. The SSD400M also delivers up to
56,000 read and 24,000 write IOPS, reaching speeds 100 times faster than HDDs, allowing
rapid access to “hot” enterprise data for improved productivity and operational efficiency. Since
fewer SSDs are required to achieve the same HDD IOPS performance, the Ultrastar SSD400M
family offers significant value in terms of IOPS per Watt, while reducing total cost of owner-
ship (TCO) through low power consumption, efficient cooling and reduced space requirements.
The Ultrastar SSD400M combines enterprise-grade MLC 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. This MLC SSD from HGST
achieves an extraordinary 0.44% annual failure rate (AFR) or two-million-hour mean time between
failure (MTBF). The 400GB capacity Ultrastar SSD400M endures up to 7.3 petabytes (PB) of random
writes over the life of the drive – the equivalent of writing 4 terabytes (TB) per day for five years.
For complete end-to-end data protection and reliability, the Ultrastar SSD400M 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 SSD400M family is backed by a five-year
limited warranty, or the maximum petabytes (PB) written (based on capacity).
