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 ownership (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).
