- SLC NAND flash for ultra-high performance and endurance
- Best IOPS/Watt for reduced TCO
- 6 Gb/s SAS or 4 Gb/s FCAL interfaces for maximum throughput
- Advanced Power-loss Data Management technology
The Ultrastar SSD400S family delivers the highest sequential throughput, up to 535 MB/s read / 500 MB/s write, and up to 46K read / 13K write random IOPS. Reaching speeds 100 times faster than HDDs, SSDs enable 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 SSD400S 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 family combines enterprise-grade SLC NAND flash memory, advanced endurance management firmware and exclusive Power-loss Data Management technology to extend reliability, endurance, and sustained performance over the life of the SSD. The Ultrastar SSD family achieves an extraordinary 0.44% annual failure rate (AFR) and endures up to 35 PB of random writes over the life of the drive - the equivalent of writing 19.2 TB per day for five years. For complete end-to-end data protection and reliability, the Ultrastar SSD400S family incorporates the T10 Data Integrity Field (DIF) standard, extended error correction code (ECC), Exclusive-OR (XOR) parity to protect against flash die failure and parity-checked internal data paths without an external write cache.
