Proven enterprise storage experience

Hitachi GST leverages decades of proven enterprise storage expertise in Serial Attached SCSI

(SAS) design reliability, rmware, customer qualication and system integration to the new Ultrastar

SSD400M solid-state drive (SSD) family. The synergistic relationship between Hitachi’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 Hitachi GST 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 efciency. Since fewer SSDs are required

to achieve the same HDD IOPS performance, the Ultrastar SSD400M family offers signicant

value in terms of IOPS per Watt, while reducing total cost of ownership (TCO) through low

power consumption, efcient cooling and reduced space requirements.

The Ultrastar SSD400M combines enterprise-grade MLC NAND ash memory, advanced endurance

management rmware and power-loss data management techniques to extend reliability, endurance

and sustained performance over the life of the SSD. This MLC SSD from Hitachi 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 ve 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 ash 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

ve-year limited warranty, or the maximum Petabytes (PB) written (based on capacity).

One gigabyte (GB) is equal to one billion bytes, one terabyte (TB) equals 1,000 GB (one trillion bytes), and one petabyte (PB) equals 1,000TB (one quadrillion bytes) when referring to hard drive or solid state drive capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning of the drive, the computer’s operating system, and other factors.

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.
