- 2.5-inch SAS 6 Gb/s SLC NAND solid state drive
- Reaches speeds up to 100 times faster than HDDs and endurance up to 5 times higher than MLC-based products
The Ultrastar SSD400S.B delivers high sequential throughput, up to 536 MB/s read and 502 MB/s write (6 Gb 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 Ultrastar SSD400S.B family offers significant 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).
