Ultrastar® SSD400S.B
The Ultrastar SSD400S.B family combines enterprise-grade
SLC NAND ꢀlash memory, advanced endurance management
ꢀirmware 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

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 eꢁiciency.
Since less SSDs are required to achieve the same HDD IOPS
performance, the new Ultrastar SSD400S.B family offers sig-
niꢀicant value in terms of IOPS per Watt, while reducing total
cost of ownership (TCO) through low power consumption,
eꢁicient cooling and reduced space requirements.
