Ultrastar SSD800MM

Maximum Performance, Reliability and Endurance
The Ultrastar SSD800MM delivers high sequential throughput, up to 1200MB/s read and 700MB/s write (12Gb/s SAS). The Ultrastar SSD800MM also delivers up to 145,000 read and 70,000 write IOPS, reaching speeds >100 times faster than HDDs and double the speed of current 6Gb/s SSDs, allowing rapid access to “hot” enterprise data for improved productivity and operational efficiency. The Ultrastar SSD800MM 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 SSD800MM family 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. The Ultrastar SSD800MM family achieves an extraordinary 0.44% annual failure rate (AFR) or two million hour mean-time-between-failure (MTBF). The 800GB capacity model endures up to 14.6 Petabytes (PB) of random writes over the life of the drive—the equivalent of writing 8 Terabytes (TB) per day for five years.

For complete end-to-end data protection and reliability, the Ultrastar SSD800MM 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 SSD800MM family is backed by a five year limited warranty, or the maximum Petabytes (PB) written (based on capacity).
