Western Digital Ultrastar DC SS300 2.5" 400 GB SAS MLC

Increase Productivity and Operational Effi ciency
by Boosting IOPS Performance with SAS SSDs
As data centers and enterprises struggle to manage the growing abundance and availability of data, the next generation of SAS SSDs with enhanced performance and endurance arrives to help address data access challenges. The Ultrastar® DC SS300* solid-state drive (SSD) is offered in a 2.5-inch small form factor that delivers ultra-high performance to power through the most challenging workloads.
Designed with a 12Gb/s SAS interface for seamless integration into enterprise environments, the Ultrastar DC SS300 delivers high sequential throughput, up to 2100MB/s read at 14W power. Available with capacities from 7.68TB to 400GB, the DC SS300 delivers up to 400,000 read and 200,000 write IOPS—double the speed of current 12Gb/s SSDs—providing rapid access to “hot” enterprise data for higher productivity and operational effi ciency. The Ultrastar DC SS300 family offers signifi cant value in terms of IOPS per Watt, reducing total cost of ownership (TCO) through low power consumption, effi cient cooling and reduced space requirements.

Data Durability and Security with Industry-Leading
Quality and Reliability
Ultrastar DC SS300 combines enterprise-grade 3D MLC or TLC NAND fl ash memory, advanced endurance management fi rmware and power loss data management techniques to extend reliability, endurance, and sustained performance over the life of the SSD. The Ultrastar SAS SSD family achieves an extraordinary 0.35% annual failure rate (AFR) or 2.5 million hours mean-time-between-failure (MTBF). The 3.2TB 10 DW/D capacity DC SS300 SSD endures up to 53 petabytes (PB) of random writes over the life of the drive—the equivalent of writing 29 terabytes (TB) per day for fi ve years.
For complete end-to-end data protection and reliability, the Ultrastar DC SS300 incorporates the T10 Data Integrity Field (DIF) standard, extended error correction code (ECC), Exclusive-OR (XOR) parity to protect against fl ash 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 DC SS300 is backed by a fi ve-year limited warranty, or the maximum Petabytes (PB) written (based on capacity), whichever comes fi rst.
