ZeusRAM SSDs from HGST deliver DRAM-like read and write speeds with the persistent data storage of flash. ZeusRAM is an enterprise-class, power-safe, flash-backed DDR3 RAM drive targeted at high write transactional environments requiring fast write commit capabilities for speeding up end-user application throughput of NAS and unified storage appliances. During the life of the product, enterprise applications can write to ZeusRAM at extremely high speeds 24 hours-per-day, 365 days-per-year, year-after-year, the drive will not wear out - even under the most write-intensive workloads. HGST's PowerSafe Technology provides critical data protection with instant data backup and recovery in the event of power interruption. ZeusRAM has the additional advantage of being hot-pluggable, so SSDs can be swapped in and out without system downtime. ZeusRAM has two ports that can each run independently. The two ports are connected to two separate hosts (HBAs) to provide for a redundant or high availability configuration. It is also possible to connect the two ports in a dual-port mode and run multipath I/O drivers (MPIO) which are available with standard operating systems to achieve higher performance.
